6 Frequently Asked Questions about “How big a resistor should I use to make a 24v inverter”
Is 20R a good voltage for a 48V inverter?
20R at 48V is about 2.5A or therabouts, I'd suggest that will be just fine, give it a suitably rated switch and you're good to go. You're just trying to avoid that massive (almost infinite) current splat when you first connect the discharged inverter. The Seplos 48V BMS has a 51R 10W pre-charge resistor for about 1A pre-charge.
Can I use a 12V or 24v battery to power an inverter?
Therefore, if you are using voltage to power the inverter circuit, you want to use 12V or 24V ideally. The 12V would be a single battery, while the 24V would be 2 batteries in series, yielding 24V. So using a different voltage won't fundamentally change the circuit or not make it work, so you can modify this.
How much current does a 20R inverter need?
Thailand, just north of Bangkok. 20R at 48V is about 2.5A or therabouts, I'd suggest that will be just fine, give it a suitably rated switch and you're good to go. You're just trying to avoid that massive (almost infinite) current splat when you first connect the discharged inverter.
Is a 20R resistor enough for a 48V BMS?

How many watts is a 120 volt inverter?
Power is a function of voltage vs current. So if the inverter puts out 120 volts and can output up to 12A of current, it has a power rating of 1440 watts. The maximum watts our circuit can deal with will be a function of the power transformer used. You have to check your power transformer for the maximum current it can output.
