@decryption@aus.social @mattrobertson@aus.social when we got our Sigenergy battery I got them to move our existing EV charger onto the Sigen gateway's "smart port". This feature lets you enable or disable "battery boost" for the connected load (i.e. does it discharge the battery or not). Plus can switch that load on/off manually, or automatically based on PV surplus. That said, in retrospect I think I overthought the "don't charge car from house battery" thing. When the car has needed charging at full power (rather than only from surplus solar) I have let it discharge the house battery, like Matt says might as well use the free energy you already have stored. Probably if the car was charging like that all the time I wouldn't do it though, to avoid the accumulated charge cycles on the house battery. 🤷♂️ Edit: clarified about surplus solar

@decryption@aus.social yeah I know what you mean - I don't have a battery yet but I plan to do that, often I'm out driving when it's sunny so I'd like to be able to top the battery up from the home battery when I get home (or some days there's spiky solar power because of cloud, plug the car in later when the home battery's charged up a bit)

@decryption@aus.social @mattrobertson@aus.social how often have you charged your phone from a power bank though?

@decryption@aus.social @mattrobertson@aus.social it makes heaps of sense if you have a big enough battery and you don’t have your car at home during the day
