I have my quattro currently limit set to use 15 amp shore power. (1800w at 120v). It will use this faithfully and my loads are usually about 1000w so my battery is always topped up. When my water heater cycles on the system correctly assists and takes 15a from shore power and the rest from battery. So far exactly what I would think, but then when the water heater goes back off and my needs go back to 1000w, the shore power drops to providing 6amp and the rest come from battery and discharges my battery.
Basically assist mode seems to get stuck "on" and it keeps assisting after the load would be totally met by my shore power connection. (load 1000w and shore power gets "stuck" only providing 600w and the quattro taking the rest from battery).
Any ideas? I have firmware version 469
