If anyone has any questions about photovoltaic or micro wind turbines, batteries, relays any off grid electronics I love talking that shit! No esb here. The idea of an off grid pv grow very interesting stuff =D I'll start with my own question we convert dc to ac back to dc again to run our lights, has anyone ever thought about skipping the ac phase and running a dc only system directly from the battery? One could even use a battery just to take advantage of cheaper rates

Depends on cable length from converter, DC drops more voltage over distance than AC

@zn you could put the battery bank right beside the tent, there is efficiency loss in converting(inverting) between dc to ac(and back to dc). You normally would use dc between pv and charge controller....to me it seems like a good idea I think some leds even run at around 24v ish, it means one less component in your system maybe a bit awkward tho

@zn what voltage do your lights run at? What is the price of a watt?

@zn my main angle here is, to run your home thru the winter means to have an over sized system every other season seems like a good idea dumping excess power into food production =D
