I’ve just finished installing (and automating) a 16.1 kWh home ESS system using a Fogstar Battery and Victron Multiplus-II inverter.
It took me a while to get the design nailed down, the install and commissioning was painless, automating the charging using the Octopus Home Assistant integration was a little (significantly) more challenging.
I’m sure I missed a trick somewhere to make it waaay easier.
There were a couple of bits I couldn’t find anywhere else, so I ended up building; such as the Payback Calculator for the investment in batteries and quite a lot of the automations in home assistant.
To hopefully save someone else doing all the research, I wrote it up here (Personal Blog, No Ads, No Tracking)
