The stackable battery systems sound like an easy way to expand the system if needed. Does the inverter get hotter as it is mounted on top of the batteries, or do the batteries run cool all the time? My friend & colleague sent me a copy of his quote for a system install here is the quote: EnergySA-Solar_Quote-Korb X.pdf I must admit after reading the document and seeing the ability to charge your car, transfer energy from car to system and its ability for relatively simple expansion I was seduced. Of course, my house was setup for 3 phase which was a way of sending excess solar to the grid, up to 15kW, which was great when the FIT was 20c/kWh & life seemed good. Then of course over a few years (since beginning of 2020) the FIT has incrementally reduced to bugger all, some providers actually charge you for any grid feed in. Up until the beginning of this year we have not paid one cent for electricity since 2020 due to the bank of credit we had built up. The energy company we were using, Engie, now have a "great" continuous feed in tariff but they charge $2.193 per day for the poles & connection to their supply, they have a peak time usage rate of 68.926c/kWh. This equates to ~ 730kWh I need to feed back to the grid just to break even with the supply/connection with no usage added yet. Sure, there is another supplier that charges $1.01 a day for connection/supply and their FIT is 5c/kWh, which still equates to over 600kWh/month to break even.  I am gambling that I won't need to import any energy on going so now I'll try to cash in on the 9c FIT whilst it lasts. I'll post this now before I lose it......
