MNDIY3024/3548/5048 Setup to run off INVERTER as Priority:
PARM = SBU (Run off inverter and switch inverter AC out (LOADS) to AC in when battery is low per settings)
PARM = SOL (Adds one more requirement along with low battery switch to AC IN, only switch LOADS to AC IN if PV drops out OR low battery PARM is reached. This allows MAX Solar power use and keeps the battery at a higher level of charge if desired as PARM can be set up higher to maintain a higher battery SOC instead of draining it to say 10% SOC as SBU can)
PARM = VOLTS will switch from inverter feeding LOADS to AC IN feeding LOADS IF/WHEN/OR AC in has 120VAC, otherwize PARM volt setting starts PARM TIMER, then if AC LOADS if still on INVERTER, AC OUT is shut off. If PARM absolute LOW BATTERY SETTING is reached BEFORE TIMER times out AC from Inverter will be shut off immediately!
AUX RELAY will ACTIVATE on reaching PARM setting.
AUX RELAY will OPEN on reaching PARM setting.
PARM HAS to be LESS than PARM (ABSORB V) or it will never shut off until ABSORB timer is done and FLOAT is reached.
PARM is the voltage to switch back to inverter running & shut off generator.
PARM may need to be set equal to FLOAT PARM
