true I don't generate much power and don't have many batteries. I am still experimenting but my goal is to be able to run my work shop off grid with the ability to feed the house during a power outage,When I get more solar and build a better wind generator I will expand the battery bank accordingly. the biggest cost other than the batteries is a good inverter,a 2000 watt inverter will run all my lights, circulator pump on the wood boiler and small power tools at the same time but won't start large motors like a table saw,I know even with a huge wind gen and lots of batteries big machines will drain them fast so I built a back up gas DC generator that I am trying to run on wood gas but that's a whole different subject. If I ever do generate enough power to meet this lofty goal I was hoping to find an alternative to a $2000 inverter and put the money into more batteries but it looks like I will need a big expensive inverter. Of course I'm not going out to buy one tomorrow,at this point I still need lots of other stuff first. I just want to get some idea of what I will need over the next few years. Or am I jumping in way over my head??
