Hey all, I currently have a single 250 amp hour battery (and two 100 watt panels) and have realized that it's not enough.  I know that when setting up a solar system setup that one should not attempt to just add another battery.  It's preferable that if one has two batteries, that they should...

Thanks.  I found an autozone that charges deep cycle batteries overnight

I see, thanks.  Should I ground the negative, or just clamp positive to positive, and negative to negative.

Hey all! So I picked up a multimeter like everyone suggested. A Renogy tech helped, and we determined that the panels and controller are fine. I had the battery checked and it's reading low at 11.8v. Renogy is asking me to charge battery up to full with either shore power or generator so he...

Battery still not charging. Not sure if I feel comfortable troubleshooting this issue after doing some research. Are there places I can bring this to to help? I'm in Michigan, but am willing to travel to other states. Thanks

I will check the cables to the controller.  Thanks

OK, thanks

I think it was my fridge and fan.  I will have to look up the specs again

I think you're right.  I disconnected the negative battery wire from the controller side, and it's floating at 14, and the SOC is reading 100%.  Battery light on the controller is flashing green signifying  battery is full as welll.  Not sure what this all means

Yes, it used to float around 13 & 14 when the battery was close to being full, or full.   I unplugged the panels and the battery, then reconnected.  Still the same.  Panels read 16.3 volts coming in.  Battery charging at 3.5 volts, and reading at 11.8 v

Interesting, I'll look this over. Thanks

The wires are 10awg. I have the panels wired in parallel. I will take the steps you recommended and see what happens. Thanks

I don't know how to test with a meter at this time, but I will research how to do it so I can see. It has been working fine since last week. I don't recall whether I hooked the battery up first... I did follow the order provided in the manuals.  I've also never disconnected the battery while...

Unfortunately I don't have another way to charge it like a solenoid. The setup is about 6 months old

I don't know how to use a tester, but I will Google. I will also reach out to Renogy. Thanks

Also, when it's charging, the meter shows it float to as high as 12.1 volts

How do I do that?

I have a renogy 40 amp mppt controller, and a UPG 12V 250AH AGM Sealed Lead-Acid Battery. The connections seem clean, and I've cleaned the panels every morning.

Hey all!  I'm on the road right now, and my 250 amp hour deep cycle battery stopped charging.  After letting the system rest for 3 hours, it's been reading 11.5 volts on my meter for the last three days with good sun. I'm getting about 4.5 amps going to the battery, and the two 100 watt panels...
