I have a solar off grid system consisting of 12 100w 12v mono panels which are set up 3s4p with an inline fus at each string, 50a circuit breaker(acts as disconnect switch), renogy 40amp mppt charge controller, goes thrpugh another 50a circuit breaker, 4 LiFeBO4 batteries 100ah 12v hooked up 2s2p, 150a class T fuse, 2000watt 24v samlex pure sine wave inverter all hooked together in that order. Then I have one hardwired outlet for appliances and I'm also utilizing the inverter plug ports too.
Everything has worked well. We just moved the panels to catch the winter sun. Then we get hit with storms and after a bunch of rain I notice no solar panel power is registering one morning. Not only that but our inverter is still on but the batteries have been drained to 0.5! They've been completly emptied! My charge controller is set to the correct parameters and will read 26.4 when there is plenty of sun, may read 25.5 if it's overcast. It drops to 24.3 at night somrtimes andcan go lower all the waydown to 21.5 and that's the max discharge it will allow before it beeps and the inverter gets shut off. I was shocked by what I saw.
This has never happened, but say I didn't hear the beeping for the shut down-would everything stay on until my batteries fully drained or would there be an auto shut down that would take place in the case I didn't manually do it?
Also, what could cause this to take place? Before going to sleep it read at 24.4 and I had no concerns because that is normal to see at nightime. Why on this night with nothing on but a fridge while we slept would my batteries be zapped down to nothing?
If I did sleep through the inverter beeping (or is it the charge controller that beeps?), would everything still continue to run until the batteries were at nothing? My previous inverter would kill the power at a certain point if it was not manually shut down. I presumed that would be the case with this one too.
My husband was concerned about the mc4 connectors being exposed in the rain during the setup. I told him they are waterproof. He took my word for it and I know I'm right but could rain cause this type of a problem and how? It was a heavy rain. When I went to check it out I noticed one of the connectors was submersed in a puddle. I removed it from the puddle. I also noticed at least a couple didn't look like they were fully screwed shut tight because I still saw some of the thread where you twist them shut.
How do we troubleshoot this? What do we do? Thanks for your help!
