Once my system uses the batteries to 20% it switches to grid and will not switch back until the batteries are at least 60%. This seems odd to me, if the grid went down and my batteries were less than 60% would I be out of luck? I have it set so only PV charges the batteries.
My System:
2 EG4 3Ks in 120/240 mode
3 EG4 5K batteries
16 used 240w panels
My Settings:
Program 01 SUB - Utility will provide power to loads at the same time as solar if solar is not sufficient (paraphrased).
Program 43 Point back to utility if state of charge is 20%
Program 44 Point back to battery when state of charge is 60%... the lowest setting it will go
Program 45 Low DC cutoff state of charge 20%. I could go as low as 5%.
