Is there an alternative to the powerwall that is functionally similar, in terms of power density and utility, but doesn't have things like a network stack and other wifi / IoT / "smart" features ?

We are just about to install lithium battery backups in our home and, of course, the Tesla powerwalls are an obvious choice, but I don't look forward to having to disable/reenable the network connectivity on them, manually, in some cat-and-mouse with Tesla for updates or whatever...

In fact, I'll bet that most (all ?) of the updates that Tesla has to send the powerwalls are for the update system, and accompanying network stack, itself ...




Yes, I'm in France, I contacted the Italian reseller for this company:

I got this instead of a powerwall because 1) price per kwh 2) tesla will not let you install your own powerwall, you need to go through an installer and attract all those associated costs (which are significant) 3) better integration with a mixed solar equipment install and pv array 4) powerwall does not support an offgrid installation, or at least did not when I looked into it 5) has canbus to a BMS, you're never obligated to connect to the internet


Used Nissan leafs are pretty affordable, might make a nice powerwall.


What is the reason you can't store excess on the grid?


Punitive pricing, or at best you're at the mercy of the grid operators and power companies.


Nothing close in terms of cost per kwh.
