We have 4x 100 Renogy solar panels (2x100 set up in parallel and then those are connected to the other 2x100 parallel panels and then those are connected in series - running into 2x100ahLiFe Renogy batteries (set up in parallel), Renogy Rover 30amp cc and a 1000 watt inverter (you guessed it - Renogy).
All seems to powering up beautifully with sunshine in Georgian Bay, Ontario. It is an off grid cottage on an island - so accessibility to get stuff is challenging.
We are using a Sunfrost DC fridge which uses 20amps on start up and then 8-10 while running. It does not run through the CC, just to the batteries. (Thru a fuse panel)
We charge phones, tools , etc - nothing else major (and only during sunlight)
The fridge is now turned off at night because even with the 2x100ah batteries, it was draining the fully charged batteries down to 0 and we had a ACR warning on the cc.
We have turned off everything at night now. Night before last, there was no load on the cc (not even the inverter) and all was fully charged upon going to bed. (77ah stored and 100% battery). In the morning the cc showed 0 AH.
Last night, again, no load (except for the inverter). From 10:30pm until around 5am , the reading was consistent. 13.1, 97% battery and 27ah. But by about 6am, the AH had dropped to 0 - still no load.
What might be causing this battery issue? Is it possible we damaged the batteries somewhere in this situation?
We are installing another 4x100w panels today - but truly, the issue does not seem to be with charging.
We are using all of the correct gauge wiring and have confirmed proper connections throughout
Also, we will be attaching the Renogy BT module for “battery monitoring” and I am ordering an actual battery monitor with shunt today - but won’t get it up here for another week or so.
Welcome your expert thoughts. The batteries are still under warranty (purchased last Summer and brought home for the winter to go into “shelf mode”
We watched many YouTube videos, have Will Prouse’s book - but are very much “newbie’s” with this. So much so that I have to read many of the posts, which may have similar issues, over and over again to see if I can decipher the language.
Thanks!!
