Hello,
By reading a lot of informations, i can see that a pre-charge resistor (or light bulb) would be required/safer to prevent breaking the inverter.
I’ve heard that we would need a 100W light bulb 24V if we go that route ? Would it be good or it need to be 50W ?
I use one of these. I have a 1200VA 24V and put a jumper accross the negative on the 2 pole breaker.
Yes. Be gently on the inverter. I myself use a 60V laboratory power supply. This way I can use one piece of equipment for 12, 24 and 48 volt inverters. And not just to charge up the capacitors but also test MPPT’s.
You could make or purchase something like this: Inverter Pre-Charge Assembly | Off-Grid Power Systems
The official way to do this is to wire up the remote voltage sensing via a 2A fuse or breaker. This is then closed first, and the main caps charge through the internal 120 ohm resistors that are designed for this function.
