That's one heck of a system you have. Maria and I are looking forward to the day that we never have to plug in again. I suppose we're actually close now, as long as the generator is available if we use to much power and the batteries get low.
Thanks for your service as well Reed. Back in the mid 60's being an airborne troop was a lot different than it is these days. Men were men once, now days in basic training they have what is called a "Stress Card". If the drill instructor gets on their butt they can pull out the stress card and he has to back off. Unreal! Never once in the 4 wars I was personally involved in (Grenada, Panama, Kuwait, and Iraq) did the enemy allow me a stress break, lol.
The total cost of our solar/LFP battery bank was $16K. Son designed and fabricated as family project and we only paid for the parts at his contractor rate.
The LFP batteries were around $6K for the set to include battery management system. The price for LFP is going down. the 8.6 kW-hr (48 V nominal) storage is probably more than we really require. Half of that or around 4 kW-hrs is probably sufficient for most purpose since that is 3.2 kW-hrs of usable energy. Our battery bank weighs 250# and an equivalent lead acid would weigh almost 1000#.
Thanks for your service. I was parachute infantry with 173rd Airborne Brigade in RVN 1966-67. I wound up as team leader with 173rd Airborne Long Range Reconnaissance Patrol Platoon. ETS'ed April 1967.
