Inverter/Charger input from Genny
I have spoken to a solar dealership about buying a Victron Multiplus 1600va 24 volt inverter/charger , they tell me that my 1.8kw generator will not be big enough to charge my batteries . The charger on the Inverter/charger is 40 amps , I cant get my head around why not . At present I have a quality Battery charger and my generator is not struggling at all when charging my batteries at 35 amps while at the same time providing power into the house for appliances , lights etc at 500 watts . I am told the Inverter/charger will draw a lot more than a regular battery charger even if the unit is only charging the batteries and no load from the house it still wont be big enough . Obviously I dont understand something , to me If a battery charger is sending 40 amps to a battery at 24 or 25 volts then its drawing around 40 x 25 = 1000 watts so why wont my 2200kw ( 1800 watts constant ) Honda Inverter Generator manage it , can anyone explain what im missing ? . The dealer said its a constant problem and they have to check with Victron what size generator to tell their customers to buy before selling them an Inverter/Charger .
