I have a nuwave induction burner that pulls 1300 watts. It is possible to use it with two 170AH Renogy batteries and a Victron multiplus compact? Do I'll get enough output power from the Renogy batteries?
you could, but based on the specs its not too healthy for the batteries in the long term.
The batteries are capable of discharging 100A each which would be more than enough for the 1300 watts. But the manufacturer is basically saying you won't get the expected lifetime if you choose to draw that kind of power - see below.
The battery's nominal specs are rated at 0.2C which means 170*0.2 = 34Amp per battery.
34A per battery * 2 = 68A all up, then *12v = 816W. You're out by nearly a factor of 2 for the burner, using the 0.2C nominal. This is before taking into account inefficiencies from the multiplus.
