Victron Energy SmartSolar MPPT 100V 30 amp 12/24-Volt Solar Charge Controller (Bluetooth)

I use this connected to my VENUS Os on a Raspberry Pi. It was a little tricky to set up but it has been running great. With this setup I can access the MPPT controller from my phone anywhere now. I also connected by 2 JK BSM as well so it that can be read from the internet too. Much appreciate Victron making the project Open source. It is a high quality interface. As for the MPPT controller it runs 8 to 10 hrs a day at max output of 15A since I have 400W of panels connected and I rotate them during the day for optimum angle. The unit runs cool and I have had no issues.

The controller seems well constructed. However, I could not get the blue tooth to connect consistently. In fact it failed to connect more than succeeded. Also. had difficulties getting 10 gauge wire to connect to the controller. I finally was able to but it took some effort. Fix the blue tooth and Ill try again maybe, but for right now Ill pass on this one. UPDATE UPDATE. Was contacted by EDEN Products and they did provide assistance and get me running. The problem is the Android app has issues where the Apple app does not. I loaded the app on my iPad and everything seems to work so I will keep the controller. Below is my response to EDEN Products: Put the app on my iPad and everything seems to connect. I will update/upgrade my review on Amazon. You folks need to get the Android problem resolved. I should not have had to go thru all of this for the money this controller cost. Also when doing a firmware update it required the scan code be entered but on the app all it said was Enter the code off the controller. It didnt specify what code, where it was located or anything like that. The thing is also very hard to read off the label because the print is so small. Speaking of small print I had to download the manual because I could not read the VERY small print in the enclosed manual. Its things like this that cause people to want to purchase from you in the future or not. I revised my rating from 2 to 3 stars and kudos and thanks to EDEN Products for their support.

Replaced a non working controller in a RV.

I have a basic 60W setup. 2 panels, one is 50W and the other 10W hooked up in parallel to get 60W. I use it to keep a simple sealed led acid battery charged to run 12V exhaust fans in my apartment. That is all! very simple setup. I had a chaep PWM controller prior to setting this up but I have seen on YouTube that MPPT is the way to go to get the most efficiency so I decided to get this small controller from Victron. Physical hookup is very clear and simple. Connect the battery first, then the panel and then load. At least this is the way I did it. Everything is working so far but I had to custom configure my battery type because Victron did not add a simple lead acid battery preset into the app so I had to manually input my values. I had to reduce the charge amperage to 2A because that is what the small sealed lead acid battery specifies. It has several presets for Victron branded batteries though. This is a very similar way of thinking like Apple does with their products. In other words, they dont like to play well with others and that is bad. It limits the ease of use and configuration of equipment that can be used with this controller. It definitely can be done but Victron Energy is not making it easy. The main complaint is the size of the manual. The font is microscopic and basically unusable. Why include it if you need to use a microscope to use it? For the money that they charge for this and the low cost manufacturing in India they should for a few cents make a bigger manual and a bigger box for this product. I will update this review if I discover any problems in the future as I had this hooked up for 1 day so far and it has been cloudy too.

I have three Victron Energy solar charge controllers of different sizes. I love them all and personally think they are the best. They perform flawlessly and are extremely efficient. The controllers all have the same configuration interface per Bluetooth with the Victron Energy App on iPhone/Android. I can set up fully customized charging profiles easily and can see the performance at a glance. The controller is small and robust, weather proof and is a great value for its performance and price. I will say that if you attempt to get any support from Victron Energy, forget it. You are out of luck and have to go to the dealers for help. Please check who the dealer is before you buy so you have someplace to turn to for support if needed. Because of the support aspect, I give this controller 4 stars. I wish there was a better support system for customers.

I purchased a couple 100W Renogy panels for our travel trailer as dry camping opens up a lot of sites for us and I don’t like firing up the generator unless I have to. The panels are deployed on folding stands which is really the only way to get them in the sun in the wooded campgrounds we frequent. I used them the first weekend with the PWM controller that came with the kit. It blinked nicely at me, but even with a voltmeter added to our control panel inside the camper there wasnt really a way to see what was going on. I started looking at adding monitors with shunts, but things start getting rather involved for my particular setup. At home in the off-season the camper is covered and plugged into shore power to keep the batteries up. I realized a few things. First, I’m paying for electricity to charge the batteries when I have two solar panels in a box. Second, the on-board inverter/charger is OK for maintaining batteries, but really lacks the ability to keep them at a full charge as they hover around 13.4-13.6 volts regardless of battery condition and with no temperature compensation. Third, to charge the batteries requires the battery kill switch to be on, meaning I’m also powering gas and carbon monoxide detectors and who knows what other parasitic loads in the camper. Not a monetary issue but things without power on them can’t cause unforeseen issues. I had originally fallen prey to the argument that you’re better off buying another panel vs. paying for an MPPT controller. That works on paper but I realized that I’ll set out 2 panels, but I will never set out 3 or 4. That meant the Victron SmartSolar 75/15 would work nicely and the cost was within my threshold of pain. The need for a separate monitor was also negated. Installation was easy as I was just replacing the PWM controller. My setup is a couple of group 24 lead acid deep cycle batteries with around 160ah. Power is brought into the storage bay of my travel trailer with 4/0 wiring where it splits off to a 3000/6000 pure sine inverter. The Victron is wired into the 4/0 cables which are only about 18” away with 10 gauge cabling. The Zamp plug that came with the camper was replaced with a 10 gauge wire unit, and the 20’ of Renogy cable going to the panels is 10 gauge. The storage bay isn’t heated so it’s within a few degrees of the batteries which are on the tongue. After doing an update the unit automatically selected 12v and the default charge setting was for deep cycle gel batteries. I was initially a little worried that there wasn’t a specific setting for lead acid batteries but the parameters of this option are apparently fine from what I can gather. Equalization is off by default. After installation I zipped the camper cover back up all I have to do now is walk by and log in to see what’s going on, no need to unzip/unlock or interrupt my nap when we’re actually camping to check our state of charge. The attached screenshots were for the first few days. I’m only using one 100W panel as I felt this would be sufficient. The battery bank was at 90% charge the first day (see handy chart) and I was pleased to see that it got fully charged but concerned that my 100W panel was only putting out 35W in full sun. A 100W panel is going to max out somewhere around 70W in the northern hemisphere on the best day in the summer and this was in January, the lowest amount of available solar energy (insolation) of the year. The following days were even worse until I understood that Pmax isn’t your panel’s peak wattage, it’s the peak that the controller will draw from the panel as it manipulates current and voltage to get what it wants. You’re not going to see a Pmax that resembles the published output of your panels unless you have a big load on them (or drained batteries) and maybe not then. This is a layman’s explanation, but if it keeps you from thinking you have a bad panel or connection it’s worth the keystrokes. Of the following three January days the first was sunny, the next was cloudy and the next was rain. The Victron doesn’t care, it still pulled plenty of voltage out of the panel and quickly went into float. It’s like a honey badger. Perhaps more interesting will be what happens when a live load is applied (such as when we’re actually camping and using power). Toggling the electric tongue jack gets an immediate response from the controller as it ramps up to offset what you’re using, then it goes back to putting the battery back to the state of charge that it wants. Comparisons between PWM and MPPT controllers are made in somewhat of a vacuum, you can spend hours reading them. In the real world of RV use the MPPT probably offers more advantages than published. On cloudy and rainy days MPPT wins, but though it’s hard to quantify it also wins when you have partial sun exposure due to your location. I love wooded/private campsites. Most examples use a sunny day with no loads and the PWM can do what the MPPT does, it just takes longer. Let’s say I’m fully charged by noon and at 4pm I decide to take a shower (water pump, exhaust fan, lights). Which one will have a chance of recovering the batteries given the limited amount of remaining daylight? Exactly.

I recently installed two 100 watt Renogy solar panels on top of my RV trailer, along with a Renogy 30 amp PWM controller with a bluetooth dongle. The panels work fine, the Renogy SCC (Solar Charge Controller) not so fine. The bluetooth app is broken, crashes frequently, and is mostly a waste of money. While the Renogy SCC did its job, the performance on cloudy/shaded days was inadequate. With a PWM SCC, you must run your panels in parallel. You cannot fully charge a battery with 13 volts available (cloudy day in trees) from the PWM SCC, no matter what the amps is. With the panels in series, that 13 volts would now be 26 volts. So I ordered the Victron SmartSolar 75/15 MPPT controller with built in Bluetooth. With an MPPT controller, you have the option to run your panels in series or parallel. Running my panels in series doubles available voltage (up to around 40 volts, which the SCC converts excess voltage to the appropriate voltage (12 or 24 volts) and current (amps) to charge your batteries. This SCC handles this nicely. The unit was delivered in brand new condition. I was surprised how small it is. There are three LED indicator lights on the front. You cannot flush mount this device. I installed this inside a wall with a vent pipe, and ran my wires out the top of the RV via the vent exit. Where I mounted inside the wall, I used a tin lid against the wood. The instructions say to mount the unit on a non-combustible surface. I stacked two washers between the wall and tin, offering a better way to dissipate heat from the back of the device. If you look closely at the picture, you can see what I did. Then I made a facade cover with a small peep hole to quick view the LEDs. These LEDs are quite bright, some people tape over them. I would try a black felt tip marker to try and dim things first. There is no way to flush mount this unit. You cannot use wire bigger than 10 AWG. Some claim 10 AWG is too big, but that just isnt so. Just dont mangle the wire ends and theyll fit. But there is a better way, read below. What I do is to tin the wire ends. Strip off 1/2 inch of wire, give a slight twist to keep the strands tight. With a good soldering iron, solder the wire end, making sure the solder flows evenly. Not too much or youll end up with a fat end that wont fit in the lugs. You might practice this with a piece of wire, but once done correctly you have a superior connection. Then after inserting the end into the lug, tighten snuggly, then loosen, the re-tighten. Each time the lug will screw down a little tighter as the lug worms into the wire end. Ill do this at least 10-15 times, until the lug is snug and secure. Be careful to not over tighten and strip the lug. Use cable restraints. Once the battery is connected, hook up the PV array. I cover my solar panels with some plywood (or some cardboard) to turn down the open voltages while I connected those, which for two 100 watt panels in series is over 40 volts in bright sun and could shock you. I also installed a disconnect switch for the PV panels, next to that is the inverter remote switch. Your battery must be connected first, then connect the PV array. The one weak area of this device is the manual. It comes with a tiny booklet that is difficult to read. You can download the PDF version from Victrons website. Some of the info is sketchy and in not so plain English. For some info you need to install another app called Victron Toolkit. This offers explanations of the various blinking LED functions. The built in Bluetooth requires an app called Victron Connect(I have an Android Nokia smartphone) for reading power outputs, managing battery charging profiles, etc. The app was downloaded and installed without issue. With the app installed and paired to my phone, the app quickly upgraded the firmware for the SCC. Once this was done, the app works very well. I can walk about 40 feet away and can still stay connected, which is about normal for Bluetooth devices. Again, the app is well done and works well. The manual has some odd English to explain some of the functions. Ill try to explain in plain English as I see it. When you first hook up the SCC, the manual says 5+ volts from the PV panels over the Battery volts is needed to be operational (According to the manual). I would expect the unit to be operational when I bought it brand new out of the box. What this really means is this; When the controller sees 5 or more volts from the PV (solar panels) above the battery volts, it turns on the charger. When the PV volts drops to 1 volt or less then the battery volts, it turns off the charger. You can tell if the SCC is on and charging with a steady blue(or yellow or green, depending on SOC(State Of Charge)) LED, or off with a blinking blue LED every 2-3 seconds. When not charging, you can still use the Bluetooth. As the day progresses the LEDs will turn to yellow (absorption mode) to green (float mode) depending on clouds and trees, and of course electrical use. With my panels hooked up in series, mine starts up right about the crack of dawn and is charging in bulk mode with a steady blue LED. With the ability to turn off charging, I have notice right off my battery is still > 80% SOC (state of charge) when it restarts in the morning, even with the propane sensor on (my only parasitic load when parked). I like the Bluetooth app. It gives you complete control over battery settings and you can use just about any type of battery including lithium. The app also has a handy history function that is very useful. Some people complain about the range of communication with the Bluetooth. Mine functions like any Bluetooth, about 40 feet of range and that is that. Even with the SCC inside a tin covered RV and me outside, it works fine. I hope someone reads this before going with a PWM charger. For a few more bucks you can have a superior solar system. But for the somewhat lacking manual, I have no cons for this device. I have also ordered the Bluetooth battery temperature and voltage monitoring device for better charging. My batteries are outside the RV while the SCC is inside, this can skew charging parameters. https://www.amazon.com/gp/product/B07RTYGMBD/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 I use two Duracell 78 ah AGM Ultra group 24 batteries along with a 1200/2400 watt inverter, so far this is working out well. This device has load outputs. For the average RV person setting up a simple solar system, this can be ignored. Run your 12 volts supply from the battery as it was originally wired. UPDATE July 1st, 2021: I have recently added two more Renogy 100 watt compact solar panes to the other two, making a total of four. To get these to work on the Victron 75/15 Smartsolar charger, I created two groups of two panels in series, then connected the two groups in parallel. Any other way would be over the rated amps or volts (depending on how the panels are connected. This setup delivers to the battery 15 amps @ 13.6 volts (float), which is as high as it can go. Volts remain the same as the original setup with two panels in series, about 43 volts. I just get double the amps. If I want to get the maximum amps I need to buy the next size up, the MPPT 100/20 controller. As it is now with four 100 watt panels, the charge controller works very well. With 4 panels connected, it turns on quite a bit before sunrise. The extra panels are very helpful in shade or cloudy days(or both). And when the sun shines, the output is strong.

The terminals where the wires connect are tiny. My solar panels use 10 gauge wire which never in a million years would fit in the tiny connectors. The manual indicates that 10 gauge will work but I had to remove about half of the strands to get the wire in. I then bought some crimp on ferrules thinking that the 10 gauge ones would fit. Nope the 12 gauge tips barely worked. I hope that these tiny wires are enough for the power from the panels and into the inverter...

I have this on a small pico hydro unit and it works well. the app is nice, its easy to use. 4 stars, not 5 because the bluetooth connection, while good, limits the usefulness of the app, would be better on wifi, and because its somewhat limiting in what you can do with it, and limited configuration without buying a bunch of other victron equipment, but if all you need is a plug and play small controller, this one is nice, its super small, looks good, and works well.

I have three Victron controllers and I love them. Glad I went with Victron. The three I have are the SmartSolar type with Bluetooth. The controllers communicate and I can monitor all of them through their phone app.
