@Disputatore@masto.pt @notjustbikes@social.notjustbikes.com 20 kWh battery cost me 7280 Euro incl installation here. 30 kWh are possible, and cost marginally more. https://www.zonneplan.nl/thuisbatterij/kosten I have other costs for a freestanding house in the Greater Amsterdam area, and while the battery costs are not so small that they are immaterial, they are not "terribly expensive" – one and a half very good Kalfhoff e-Bikes, or 1/3 annual cash bonus.

@isotopp@infosec.exchange @notjustbikes@social.notjustbikes.com that's a fabulous price. I have a quote of 3 300 euros for 3kWh of batteries plus installation. I would have to replace my inverter because the one I have is not hybrid: X1-Hybrid-3.0D- 952€ + IVA Smart meter- 125€ + IVA BMS MC0600- 450€ + IVA 3.0kWh High voltage 90V-116V Lithium Battery- 900€ + IVA Instalation- 255€ + IVA IVA is the same as VAT.

@isotopp@infosec.exchange @notjustbikes@social.notjustbikes.com when I say that the batteries are expensive I'm talking about a cost-benefit point of view. In Portugal, only one third of the power bill results from consumption. The remainder is the power availability and grid access costs. Even if I was to remove consumption for most of the year, I would still have to pay two thirds of the bill for the whole year. So the monthly savings would be fairly small. It could take upwards of 15 years to offset the investment.
