One month with a solar battery - real statistics
One month with a solar battery - real statistics
August is meant to be full of gloriously hot days. An endless parade of sunshine and drinks in the park. This year it seemed mostly grey, miserable, and prone to pissing it down at a moment's notice. We all know that solar panels' efficiency wilts in the heat, but do they get a tan work [...]
A blog post about my London-based solar panels and battery.
You're viewing a single thread.
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.
