I bought this 1K 12V inverter to get familiar with the technology before I spend the big bucks on a 48V system. I am glad I did because I can’t get it to perform as expected and I am a bit confused on its possibilities.
1. During an overload event, I would like switch to utility power then fall back to solar/battery without manual intervention.
2. In SBU mode, I would like to switch to utility when I don’t have enough battery/solar then switch back to solar/battery when its available without intervention.
For 1. When I overloaded with a heat gun, it switched to utility like expected but the only way I could get it back to solar/battery was to disconnect the utility power (maybe I didn’t wait long enough or maybe this isn’t possible?).
For 2. I encounter this same issue a couple times when my battery could not sustain me through the night. It appears when the battery reached option 12 voltage level it switched to utility as expected but the battery continued to drain to the low DC cut-off voltage and the inverter started beeping and the screen flashing. I couldn’t change settings, so I disconnected the inverter from solar, battery, and utility and waited until I had plenty of solar to hook it back up at which point it started charging the battery and operating in bypass mode.
I have three 200W 12V Rich solar panels, one Ampere Time 12V 100ah LiF2PO4 with a second on its way. Inverter set as follows: 01: SbU, 02: 50A, 03: APL, 04: SEN, 05: USE, 06: L-E (enabled), 07: t-d (disabled), 08: 120, 09: 60, 11: 10A, 12: 12.3, 13: 12.8, 16: OSO (only solar), 18: bOF, 19: -EP, 20: LON, 22: AON, 23: bye (enable), 25: FEN, 26: 14.6, 27: 13.8, 29: 11, 33-39 default.
