Some interesting data, although given the high initial cost of installation I feel those "we paid only 1£" are a bit misplaced.
Anyways, I finally scraped together some money and also got a 5kw LiFePO4 battery system yesterday. Still need to install everything DIY, but I will probably hook up some statistics monitoring system as well as the new hybrid inverter has a cool integration with the Home Assistant software.
I've been thinking of getting a hybrid inverter (rather than manually moving loads between grid power and inverter/solar power). How much did it set you back?
Slightly above 1000€ 😖 (made by FoxESS like the battery system)
Don't take it as a general recommendation as I have yet to test it, but spec wise it seems to be a relatively good value for money.
I'm curious what type of Statistics monitoring system you aiming for @poVoq. I have ordered a 3.7kw panels + special type inverter for direct heating of a boiler and a secondary boiler/other item. And i am intrigued what the monthly differences are in kWh generation and would like to track those. Only I have no idea what I can hook up between the panels and inverter to log.
The hybrid inverter I got has a ethernet connection that can be connected to Home Assistant: https://github.com/nathanmarlor/foxess_modbus
Not sure yet how I will analyse that exactly, but it might be nice to automatically publish some stuff to a website via it.
I'm exporting from Home Assistant to Prometheus and visualize that using Grafana.
