#Battery

I have a whole house battery solar system with 3kW of roof mounted panels and 9.6kWh of battery storage. I can monitor this using Home Assistant and it’s interesting to see my power usage and generation stats. Interesting, but not that relevant to daily life.

What is relevant is knowing how long the battery has left, especially now we’re in autumn/winter and the typical British weather is in full effect. As I look out my window right now it’s misty, yesterday it rained all day.

Some more stats on my home solar setup now it’s autumn and daylight seems to be a distant memory.

Here’s how my solar panels and battery system have been performing this month. I might do this more frequently, it’s hard going back in the historical data in my monitoring software and these posts are easy to find.

So I joined the Ryobi battery cult, but since their batteries are expensive I did the obvious thing and bought some off Amazon from random third party companies. The batteries seem to work well.
