I like my off-grid system, but I wish it were possible to get grid power. I would do that in a heartbeat. There just is no power for miles from my camp. My small system (two of those batteries) came to about $3-4k as I recall when all was said and done.

Hello again! We're still looking at off-grid solar. I have run the numbers once again, very lean:


* vent fan for composting toilet
* one laptop PC
* two cellphone chargers
* pipe heater to prevent water supply line from freezing in winter

* LED lighting, about 15 watts total


and came up with a daily budget of just over 2000 watt/hours. I'm now trying to size a system that will provide that, while permitting future expansion.

One retailer suggested this DIY kit:

$7500 for everything (except the batteries). Is this reasonable?
