I'm not familiar with inverters. Does anyone know how mine should be set up I have 3-deka precision built 708D w 1100cca
Equalize=??
Batt Type=flooded ( it was set to gel)
Power share=???
Batt size set to ???600ah
OK, since you have wet cells, set it to wet cells.
Power share is important if you are in limited shore power (like a 15 amp connection at home). This limits the amps of 120 VAC that the inverter/charger can use to charge the batteries. A low setting is fine unless you are running a generator while dry camping just to charge the batteries.
Each of your batteries will have an amp-hr rating. Suspect in the 220 amp-hr range. Times three for battery size.
Equalize-- maybe once a quarter.
