I want to run a 1200w induction single burner stove. 1200w is on max temperature, realistically I'll be running it around 600-900w. I'd be running it for no more than 15 minutes.
My understanding is the following would be the consumption:
Medium setting: 600w@50A but for 15 minutes, so drawing 600w for 15 mins @ 50A would be like 12.5Ah or 150wh but still at 50A.
Max setting: 1200w@100A but for 15 minutes, so drawing 1200w for 15 mins @ 100A would be like 25Ah or 300wh but still at 100A...erg
My bank is currently only 170Ah 12V AGM. I have a 2000w (4000w peak) pure sine inverter.
I have 300w of solar through an MPPT controller and live in sunny San Diego. I'm also running a DC fridge that averages about 15w at 12v and charge a laptop and phone (maybe 100wh).
Is this possible?
I've heard of people doing it. I'm aware of Peukert's law but don't know off hand what the N rating is of my batteries (two 85Ah 12v AGM).
My guess is it should work around 11am when the batteries are topped off, and that I'd be pushing the batteries pretty hard even with the stove on medium. And that running it at night when the batteries are around 90% might be pretty rough. Would my voltage drop below 11, 11.5, or 12v running at 50a or 100a for 5-15 minutes?
I want to add a third battery but heard that a new one would die quickly because I'm adding it to old batteries (about 1 year old, generally drain to 60-70%).
Thanks in advance, smart people.
