Yes batteries are getting real cheap now, they are less than half the price they were when we bought our system 2½ years ago.
With sodium battery production scaling up, those will probably be both even cheaper more durable and safer.
So a couple of years down the road, the value of buying batteries will probably be insane.
So instead of buying a big battery, we have a small one and all the devices go along with it. The house and water is heated when the battery is charging. And the setpoint is lowered when energy is expensive.
This extends our our “battery capacity” without the investment into more electrical batteries
The first 3 are me, the 4th I haven’t done (yet)
I’m thinking of battery storage to avoid that!

A battery is energy per volume.
