Battery banks.
Nickel-iron appears to be the best way forward. Twice as expensive as competing technologies, but far far longer life. They can be safely discharged by 95%. Service life is 25 years or more. The cost of ownership is half or less over their lifespan. So, looks like I'll only need to buy one bank of batteries. Ever.
