nostr:npub19lt4284mghqxekzm6n5njxurnxrxhqhrva2leusdsuu5ja5jeycq66qfjk is the arbitrage opportunity worth the extra load you put on the battery?
I’d assume it makes it wear out faster.
Also, have you considered round trip efficiency of the battery?
🆕 blog! “Review: Moixa 4.8kWh Solar Battery”
I have upgradeitis. If something newer and shinier comes out, my stupid monkey-brain compels me to buy it. Seven years ago, we installed a solar battery. It was part of an experimental project which looked at creating a community power-grid, so it came at a subsidised price. As I explained to BBC Click, the 2k…

Your assumptions are wrong. Modern battery management spreads the cycles across the individual cells - like wear leveling on an SSD.
The batteries are rated for 6,000 cycles - which is 16 years of constant daily use.
There's always an AC/DC/AC conversion loss. Ideally the battery would be directly coupled to the panels and then all our DC devices would run directly.
But those small losses are nothing compared to the money we save.
