Current Solar System The Classic 400W: 2200W Giandel Pure Sine Wave Inverter, two BattleBorn LiFePO4 100Ah batteries, Renogy PG series 40A MPPT charge controller.
After closely following Will's instruction per the website blueprint and the book I have had some recurring issues with this system typically related to over-discharge. There have been a few instances of over-discharge: the inverter sounds the alarm and the charge controller reads E1 error for over-discharge. So far, this had seem related to cloudy days or somewhat (not much) more electronic usage, but I have been unable to properly diagnose what is going on. The most current issue has resulted in a small crisis at our off-grid establishment: over-discharge alarm has gone off and the charge controller appears to have no power and no display. The fuses and breaker are intact and did not trip. the controller is currently disconnected completely and system is off to safeguard components.
I am a beginner and my understanding of the systems workings in detail is definitely lacking. I am left somewhat baffled by the problems as the battery monitor (in the placement indicated in the book) shows us having 45kWh. Our hunch right now is that some settings need to be adjusted on the controller to allow this system to function properly, but on a basic level the settings were 12v set to Li. Please help! This forum is likely to be much more helpful and direct than other sources. Thank you.
