House batteries to use with large inverter
We're planning some camping where generator use is restricted, so I want to make sure my batteries will hold up between charges. We'll usually draw less than 25 amps, but I'd like the option of runni...

The MINIMUM per Xantrex is 1pair GC2 (or equal) per 1,000 watts.. For boondocking might be a good idea to double that.
1,000 watt Minimum 1 pair (230 amp hour) double 2 pair (460 amp hour)
3,000 watt Minimum 3 pair 690 amp hour Boondocking six pair
Of course more battery is always better.
agree completely. my experience is that 1000W 1 pair GC2 is IMHO the absolute minimum and likely to mean inverter dropout at around 80% or less SOC, while 4 GC2 will work down to around 50% SOC
I'd say for 1000W the "RECOMENDED" should be 4 GC2.
the downside to GC2 batteries, very high current draw= very high voltage drop. 12V big advantage in this case
