First try at solar and it is working great. About to have a total of 300amp battery bank and 500watts of panels.

Very confused why my battery shows a low voltage but soc shows 100% until a load is put on then jumps to 13.6 and about 10 min later drops back down to 13.1, and will jump back up when I turn on the fan in my camper which is 30 watts. I checked the battery terminals with a multimeter and reads...

A solar project for home use as a learning guide to what I'll need/want for my camper that I am currently shopping for

I've checked over everything, I just swapped out the USB port and didn't change anything else. I disconnected the panel and battery. Will hook everything back up tomorrow and see what happens.

Changed the controller settings to the above suggestions, now the voltage is bouncing between 13.2 -14.6. Battery has been charged, should I disconnect the solar and drain the battery down then recharge ?. Thank you so much for the advice

Charge controller settings

Been building small power banks with old laptop batteries and charging modules from amazon. I have some brand new lifepo4 18650 cells that I would like to use, just can't figure out if they are compatible with the charging modules I have. Says 4.2 over current protection, is that too much for...

Now the panels display disconnected and the voltage is back at 13.1. Thanks for the advice, I am pulling my hair out

I built Will's 400w mobile system as an intro into solar and it worked great with 2 100ah agm batteries running most of my home electricity as an experiment for a camping rig. I have now purchased a pop up truck camper and space is extremely limited with really only room for one battery. Wanting...

Thanks for the input

Thank you, I'll go over everything. Just can't see anything different than before I disconnected the battery.

My system will seem to work till battery shows 13.9 then the solar panel disconnects and voltage drops to 13.1 , as soon as a put a load on the battery voltage jumps back up to 13.6-13.5 . Panel kicks on a few minutes later then the whole thing happens again. Disconnected the battery overnight...

My epever tracer 4210an works perfectly when hooked to agm batteries, but keeps disconnecting the panels, stops charging and drops voltage when hooked up to a lion energy 1300. The system worked fine for over a year and I thought something was wrong with the battery, but the same thing happens...

Thanks, I'll try that

Have 3 renogy agm batteries in my bank, Amazon sent wrong battery, was supposed to be another agm. They sent a gel , was wondering if it could be hooked up to the three agm batteries to avoid the hassle of a return. All are 12v 100 amp hour.

Single Itek 360watt panel, no error codes on the controller. It worked fine for a year and a half, I unhooked the battery to change a USB port and not sure if it was doing this before and I didn't notice or if it started after I hooked up the battery again. It is built exactly how was...

Disconnected the panel first, then the battery. Let it sit over night, reconnected battery and seemed fine. Reconnected the panel and it charged as normal till voltage shows 13.9 then panel disconnects and voltage drops to 13.1 till a load is put on then drops again when load is taken off

Thanks, Renogy said don't do it. Now amazon isn't excepting calls or email requests. Have a call into Renogy and we'll see how there customer service is.
