How big is a 150A 12v battery inverter

Battery needed for 1200 watt inverter

Smaller inverters tend to have low efficiency, so let''s assume 85%. That means the battery will have to supply 1000/.85=1177W. The battery will have to supply the most current when the SOC is low and the voltage is low so we are looking at 1177W/12V= 98A. 98A is within the 100A spec but it sure is cutting it close. Edit: Corrected SOC

Do I need a breaker?

I have replaced the thin 2,5mm2 with a strained 10mm2 wires directly from the controller to the battery. I plan to put a 20A breaker between the PWM and the battery, since the pwm controller is 20A. I have ordered a 150A fuse for the "+" wire of the battery - inverter connection,and I plan to exchange it for a 16 or 25mm2 strained wire.

Is there a wire/fuse size chart for 24v? | DIY Solar Power Forum

What I''m referring to is that at high current, capacitors in inverter do approximately nothing for 60 Hz current draw by a single (or split) phase inverter. The entire 60 Hz current draw comes from the battery, dropping to near zero twice per cycle. A 3-phase inverter with uniform loading on all phases would not do that.
