  2. 5Kw System setup

    nnn replied to GrahamS's topic in Inverters
    Thank you for replying, Dex_. My clueless calculation resulted in 63%. Last night the inverter was set on SbU again, and the voltage was 49.1V again at 07:00 this morning. Cloudy day today and the battery is still charging. Boiled the kettle a few times, no switching back to grid. At the moment, 11:30, the voltage is 50.4V, 96% SOC (according to WatchPower). According to my voltmeter it is 50.6V and 74% SOC according to my calculations. Thank you for the advice, TTT. I am sad to say I don't know what a BMV is!!!

  3. 5Kw System setup

    nnn replied to GrahamS's topic in Inverters
    May I, nevertheless, ask what a reasonable SOC% would be at 49.1V for a 3 month old, 15 cell 2.4kWh 48V LFP battery with float voltage 54.0V, bulk voltage 54.2V and discharge end voltage 40.6V (set on the inverter)? Reading was taken at room temperature 100C to 150C over a period of 90 minutes with no battery charging/discharging taking place and effectively no load.
