For those who may dry-camp a lot, an inverter's parasitic/no-load current might also be worth considering in addition to output capacity. Some larger inverters (>1500w) can have parasitic/no-load current as high as 3-4a. 3-4a can go-through 72-96ah in 24 hours---it adds up.

For what it's worth, we chose an Aims 2000w high-frequency inverter to power the microwave and a/c in our truck camper primarily because of its good inrush capability and low parasitic (and reasonable price). Aim rates the parasitic at .9a. We typically experience around .6 - .7a.

I know the Magnum 3000w hybrid inverter/ charger has 2ah or 48ah in 24 hours of idle draw.


12v 500ah, 20 cells_ 4s5p (GBS LFMP battery system). 8 CTI 160 watt panels (1,280 watts)2s4p,Panels mounted flat. Magnum PT100 SCC, Magnum 3012 hybrid inverter, ME-ARC 50. Installed 4/2016 been on 24/7/365, daily 35-45% DOD 2,237+ partial cycles.

parasitic load is the whole reason I want to go as small as possible. to reduce that. I'll take a look at that one also. thanks
