Hi CaptnK,
Welcome here and thanks for bringing back up an interesting subject. This was about 3 years ago and I think the better way these days is to use solar to charge the batteries. You can easily pick up for a few hundred dollars a complete 2/3 kw kit somebody has pulled off their house to upgrade to a bigger system. Sure it takes up more space but once setup it can tick along for years producing free power. Just another option
