My house is 100% solar with generator back up. No power lines come to it. The only infrastructure supplied is internet, and propane 3 times a year. Can definitely do without the propane if nessecary. Just switched over to 24v lithium batteries. We have every amenity as a normal house. It's really cheaper when you factor in maintenance and upgrading the system, but totally independent. That's the benefit.
Typo...NOT really cheaper
did you go with a 24 or 48v system? what batteries did you choose?
Originally 24v, but switched to 48v a few years ago. There's not a huge difference, but the batteries seem to hold up a little longer w/48v. We purchased used hospital back up system lithium 24v batteries. Most hospitals replace them at 90%. This was the best upgrade hands down and very reasonable. 4 of them peplaced a bank of 20 lead acid batteries and perform way better. There's a website that sells them $3-400 each(when in stock). I can post if anyone is interested.
