I got these to connect 2x 9A/30v panels in parallel into my MPP all-in-one inverter. They’ve been powering my 1985 RV full-time 24/7 for a year now so I’d give them nothing less than 5 stars. On colder climates my panels do go over their rating bringing about 24A which is 4A above the rated 20A max, but I’ve had no issues.

Received as good order. No issues to report.

Came as listed, easy to install.

These Y adapters are the best set Ive ever had, Heavy duty great quality

Works nicely.

Does what it is meant to.

4mm sq = 12AWG. The wire is pretty stiff. The connectors seem like they will keep water out and wont come undone on their own. Im probably going to cut off the single end and splice in some of my own wire, rather than buy an expensive extension. Dual wall heat shrink should work well enough for keeping water out of the splices.

I hooked up my ecoFlow solar panels and it locked my panels MC4 connector. Tried everything to get it to release. Im going to have to cut it off and hopefully wont damage my $300 solar panels cable.

i tried these on different cables and majority of the time they just slip off without having to press the clips in, I dont think its my cables or fuses since the only thing in common is these Y splitters

Great product
