Hello.
I am creating a simple off-grid installation to power a few small things off to the side. However, so far the system is not working at all and I cannot figure out the problem. I've tried getting answers here a few times, but questions have been asked when I couldn't answer them (either system was down, or winter prevented access). To address this, I created a web page which provides videos of my install, item specifications, e.g., panel specs, voltmeter readings, and anything else I can think of that will help me get answers. In trying to honor this forums rules, I replied to my original posts with answers once I had them, but apparently older posts do not get attention as nobody responded.
My system consists of:
The issues.
After a full recharge on the batteries, the system starts up and registers everything as working, i.e., the Eg4 display shows the panels feeding the batteries.
Within 4-6 days the Eg4 reveals 6p errors. After a full battery recharge, the system starts again.
I grew tired of this cycle. The winter curtailed troubleshooting, so I shut the system off and left it alone until now. This time around, I'm getting different results. After a recharge, the system starts up as usual. Within days, the system sometimes shows an error type 4 (which seams to suggest heating issues), and sometimes just shuts off. Oddly, the shunt attached shows the batteries at 100%.
I feel like i have one of 2 things going on. Either I was shipped a faulty Eg4 inverter, or these eco-worthy amazon batteries are faulty. On one hand, I think its the batteries because I had one faulty on the shipment, and another that seems to lag behind the others in charge. On the other, I think its the inverter because the batteries do show a full charge and are capable of being charged via AC chargers.
I do not know how to figure it out. What might you experts recommend?
Thanks
Jeff

My system consists of:
- 7 used panels (4 in series, 3 in series, y-branced into 1),
- 1 brand new Eg4 3kw Inverter, and 4 eco-friendly batteries from amazon. I believe the Eg4 inverter is faulty - but I cannot be sure.
- 4 brand new Eco-Friendly 12v 100amp LiFeP04 batteries. $1k less than than Eg4 batteries - so perhaps the problem lies here.
