Curious- you have solar to refresh that planned 50-100kWh pack?
I have currently three 15kw roof mounted , both houses and the steel building
I already sell power to ERCOT via a LLC and a group of other small solar system owners as a virtual power entity so yeah I have plenty of capacity or could purchase wholesale power very cheaply from my group or the wholesale market directly.
I get panels at wholesale price and have a friend and former graduate student of mine who is a solar installer do the installs and all the way to the separate grid breaker where my cousin who is a licensed electrician makes the required legal splice it’s ridiculous but you have to get a licences electrician to do the last wires. The systems started as an off grid experiment and grew and grew as more were added and profit was used to expand. It’s self sustaining now.
