1. Let's say we have the Victron 1200/24 Phoenix Inverter for my 24V battery system, (120V AC output)

2. The Peak/Surge rating for the Inverter is 2200W

3. And the efficiency rating is 91%

Let's say we have a device that has a startup W of the full 2200W. That is, the device needs 2200W to start.

Since AC Watts == DC Watts, without including efficiency, the device will need 2200W on the DC side too.

BUT, since the efficiency is .91, then, I need 2200/.91 watts = 2418W on the DC side for the

hopefully brief time the startup watts are required.

On the DC side, this is 2418/24 = 100.75 Amps

Of course, if my system battery bank is rated at 100 Amps, I am perhaps going to cause a breaker to flip (if I have it wired correctly with a 100A breaker).

Do I understand properly?

Thanks
