First, why do you want energy storage in your home? Purely backup? Or, backup and to use during peak hours? I have 12.4kW of solar panels and two powerwalls. Remember that 1 powerwall has peak output power of 5 kW. If you are on backup with a single PW and an AC unit kicks in while you have the toaster going, the powerwall shuts down. The best thing about a PW is the gateway. You should study it’s functionality.
if all you want is emergency long term power, then maybe using Lucid’s battery makes sense. If you have anything that requires seamless power through a power interruption, or you never want to draw power during peak hours, then you need a properly designed standalone energy storage system.
I feel too many people are getting all excited by Lucid’s ability to supply power without having any clue on how a properly designed energy storage backup system works. I don’t think of Lucid as a backup system. It is an emergency source of power during long term outages.
Does anyone know what the maximum continuous output power of Lucid is?
I had 2 powerwalls installed. After installation I decided I wanted a 3rd one. Tesla won’t do it!
Another eye opener for me was how the backup systems work while the grid is down. Solar recharges the batteries and supplies the home. Once the batteries are recharged, then the solar is shutdown. The house then draws down the battery to some point, then the solar turns back on to charge the batteries.
