LINKPAL Branch Connectors Connectors Y Connector in Pair MMF+FFM for Parallel Connection Between Solar Panels … (1 Pair)

I have two 100 watt Renogy solar panels and their 20 amp Rover charge controller. These allow you to connect your panels in series parallel, maintaining the voltage but doubling the amps so batteries charge faster. These appear well made and they do the job. As with most of MC4 plugs they can be hard to pull apart, so I recommend getting a disconnect tool. Theyre cheap, usually come in packs of 2 or more, and make disconnecting the cables after use a lot easier.

works great. Properly labeled. Avoid other sellers (bougerv) of similar items who ship the wrong item in the right package.

They do what I supposed to do they fit perfectly

Product works great fits to solar panels and existing wires with no downgrade in electric

I have used these for years in a 900 Watt array that runs at ~60 VDC & 15 Amps. No issues at all. I even stacked a pair for a 3 to 1 configuration as my array grew over time. No issues there. Rated at 30 A this poses no issue but I would never stack more than a pair of them. These are solid built (like 10 times sturdier than any MC4 connector ends I have ever seen). After two years they show no signs of deterioration and are still bone dry inside.

Can be used for one to multiple solar panels, and leaves just a positive and negative lead to your system.

...and hold up to elements well. Easy to install to expand and improve my charging time

Worked great!

I use the inside the roof so water resistant means the squirrels didnt pee on them and short them.

I like how easy it is to buckle and unbuckle without special tools. I bought the first set, used it for a few months, and I thought it went well. And I bought the second set, and it broke on the first day. (see photos) I guess the plastic part is not that strong. I dont know if it was already cracked when I received it, but its too soon to be broke already. I guess I can glue it back on, but since its new, I returned it and waiting for the replacement. I think since this is meant to be used outdoor under a lot of sun light and also is exposed to wind and water, its better to be stronger. Perhaps you get what you paid for.
