It's not a 2 kW load that breaks down a 5 kW inverter, there are safety devicesMatenjo wrote:Until I get a bigger inverter.
And then there is a warranty on new equipment.
To reset, you had to do it out of the sun, battery disconnected, no power for 2 minutes, just to discharge the capacitors ... Did you disconnect everything or just press the M / A button on the front?
Connect a load to the terminals of the weakest, what you have on hand, like a headlight bulb or more powerful, and make a new measurement, knowing the current flowing, you can deduce the internal resistance of the battery.Matenjo wrote:For the batteries there is not the same voltage, there are only 3 which are identical 13,4v and the other 12,2v
Before putting them in series, we arrange that they all have the same load and the same capacity, if they are not brand new at the start, it is useful to measure it.
2 60 W headlight bulbs = 120 W = 10 A ... A 150 Ah battery must last 15 hours ... CQFD
