Caldera warmstone vs batteries?
So this company says it's a boiler replacement and they say that their technology is worth about 7 Tesla Powerwalls, for 12K instead of 70K which is what Tesla would charge How true is this in reality? Would I be better off just having regular batteries? (Not necessarily Tesla)

SOLIS 3kw 5G RAI AC Charger
Has anyone got one of these charging systems for solar storage? I'm interested in whether we can store economy 7 power in it off the grid (at the moment makes a huge difference in payback times!) Also is the control app on the device itself so I'm always in control, or is it "in the cloud" and may suffer with a supplier…

Batteries are they worth it...
Hi, I am trying to get quotes for solar panels. So far only one company has responded. They have quoted with a battery and one without.
