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.

Is a 20R resistor enough for a 48V BMS?

The Seplos 48V BMS has a 51R 10W pre-charge resistor for about 1A pre-charge. 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.
