(Full disclosure: I’m in the solar industry, but on the software side. Recently left Cloudflare to join Aurora Solar as CPO.)
Berlin grants one 500€ with the purchase of a balkony solar plant.
- 12x Trina Solar Vertex S 400Wp (TSM-400DE)
- solar inverter Fronius Primo 5kW
- battery inverter Victron MultiPlus II-GX
- 8kWh LFP BYD LVS
- smart meter (zero injection setup) Victron/Giavazzi ET112
- EV charging piloted by the Victron (EVC300400300)
There was not much 400V batteries and inverters back than. I log a bit via Home Assistant, so far without InfluxDB simply because I still have to find value in logging over longer time period, pruning data etc and HA alone was time consuming to setup due to the devs passion for YAML (GRRR i HATE modern YAML mania).
Personally in commercial terms I'm DISGUSTED by the current state of thing where in China prices plunge and here in EU skyrocket, as quotes from professional installers are so high that a not-self-made system is simply economically not a good investment.
Feel free to ask what you want :-)
P.s. this thread would've been less noisy if there was a decodable email address in your profile, sweetie pie. :)
Then again, maybe you know the trick where more comments is mo' betta'. No judgement, haha.
