I've lived off grid going on five years. In that time, I've been able to test out several types of solar. I understand starting out on a budget like I did and I understand graduating to a larger system like the one I'm having delivered soon for my cabin build.
I've tried Chinese companies which worked out OK until one day the units failed and I experienced zero customer service. So although I'm frugal, I will never rely on a company that is not based in the U S again.
Signature Solar is based in Texas and they'll be there if you need customer service. That alone is every reason to stop fooling with other companies.
EG4 flexboss21 hybrid and 2 batteries currently $12000
Signature Solar sells EG4. One of my very favorite brands. In fact just yesterday I paid for the freight delivery of my new solar system.
The EG4 flexboss21 is the most powerful hybrid unit on the market as far as I know. You can run 21,000 watts of solar into this unit and it boasts a 10,000 watt inverter.
Coupled with two of their wall hang batteries I'll be piping in 14,000 watts from the pallet of panels I ordered and storing up to 28kw in the batteries. You can read all about it on their website.
EG4 refurbished hybrid currently only $600
In addition to systems like this that can power your entire house, they offer entry level systems. I get asked every day what solar I recommend and this is it.
