400W of solar + pwm controller + cables/brackets $1000 CDN
2 x Kirkland 6v golf cart batteries $320
1800W modifies sine wave inverter powering 1/3 of the rv plugs $400

I could benefit from another pair of GC batts as I am topped off before noon and have less margin to use heavy loads. I rarely bring out our Honda 2000 unless its for microwave or other big loads. Very happy with my setup and it opens up so many off grid opportunities.

By lithium next time.


It really depends on how often he needs to deep cycle. Even at 80% DoD, he can get hundreds of cycles out of AGM's, so if he only deep discharges a few time a year, he may never see a payback on lithiums.


Pulling 100 Ah out of a 250 Ah battery is using only 40% capacity. Last time I looked, 50% is supposed to be the limit without damage. And we are talking about a true deep cycle battery, designed for solar applications, not a faux deep cycle "marine" battery.

Just thought I’d post what I’m seeing. I have 400 watts of panels feeding 250 Ah (3000 watt-hours) AGM batteries. I ran them down fairly deeply, pulling 100 Ah of the 125 Ah feasible.

He has 250 amp-hours--he used 100 amp-hours. That should be no problem with AGM.

Next time buy SiO2.

My ride is a 28 foot Class C, 256 watts solar, soon to have SiO2 batteries, 3000 watt Magnum hybrid inverter, Sola Basic Autoformer, Microair Easy Start.
