I am putting together a small, (30A input from solar max) solar system for a friend, using LiFePO4 batteries with no low temp cut-off. I have heard that there is a solar controller that will do this. Anyone know what brand I need to look for?

I just finished testing and running a bonding wire from my ground bar to my neutral bar, and my system is working fine now. The 3-light tester is showing normal: just the two amber or orange lights on. THANKS A LOT!!!!

Thank you for all your help. I will do the test as soon as I get my tester back from my neighbor, then try bonding the ground with neutral, if the voltages are correct.

Yes, I got them from Signature Solar about a year and a half or so ago.

I wired the output of the growatts, (through the breaker panel next to them), directly into the old shore power cord, as this RV will never move, and I live in a community that is totally off-grid. If there is no neutral to ground bond IN the Growatts, there is no neutral to ground bond in my...

Those switches are great for AC power...but not for DC power. BIG difference! 48V DC can WELD!
