Love it! I’m trying to head that direction as well. Might as well use that free energy blasting at us from space lol. Seems silly not toOne step closer to an all solar grow. Trading has been very slow so it's been really hard to get the money together to do this project but my mom is helping me out by covering part of it. First step was to power my 5th wheel. I'll have that done by next week. The trailer only really needs 100w-200w to power the batteries running the fridge, furnace, lighting, etc... I already had the equipment to do this except for the second battery. Her donation to the cause is adding 2-3 100w panels, the second 12v 100ah battery, upgrading the charge controller, and buying misc parts/cables/mounts/adhesives. I'm probably going to remove the roof AC/heater to make room for more panels since I don't ever use it.
What's going to make it possible to use this solar generator to power the grow lights is the upgraded charge controller. The original charge controller was a 30a PWM and the new one is a 60a MPPT. The PWM was limited to 2 batteries at 12v/24v and 3-4 100w solar panels. The MPPT an run numerous batteries in 12v/24v/36v/48v in multiple configurations and up to 900w in panels, also in multiple configurations. It is 15-20% more efficient, has a variable charge algorithm, tracks cloud cover, can handle differing input/output rates, and charging is even fine tuned and adjustable enough to handle lithium ion batteries (their charging temps have to be perfect). Been putting the system together in my head but I won't be able to sort it all out till I have everything in front of me and can do mockup cable runs.

Great advice!For real dude. It wasn't a very useful resource for homeowners till recently. The increased efficiency in panels and charge controllers combined with better batteries and high output low watt lights (not to mention increased efficiency in just about every modern appliance) has made it a viable option for today's homeowners. If you're going to use it for anything other than full AC appliances (old style lights, washers/dryers, air conditioners) you'll want to buy a "pure sine" AC inverter. They are less efficient than the cheap inverters but DC circuits need to filter a fully oscillating wave form to operate properly. You "want" to use the cheap inverters to power the simple AC circuits. Aside from efficiency, the pure sine inverters with enough power to operate big appliances are ridiculously expensive and will burn out faster if used for that purpose. So you'll want two separate solar generators, one for simple AC and one for electronics (which one your microwave goes on will depend on the electronic make-up of the oven). Remember that washers/dryers, coffee makers, AC units, etc... often have two stage motors or heating elements that require short bursts of high current. That will require an inverter with the ability to provide that kind of power in bursts. The inverters are rated with a normal operating range and a max range. You want to make sure that "max" range is well above what's needed for those short high current bursts. I've read lots of complaints regarding inverters that popped fuses even though they were supposedly rated to supply the necessary current.
