      works great, i wish the SOC setting kept all batteries, regardless of their watt hour rating at the same percentages. i'm mixing two B300K with one B300 battery and the percentages are all over the place, but the average SOC is correct. I wish they were all consistent to each battery.

      Purchased 2 B300K batteries to add to my AC500. Plugged them in and turned the AC500 on. Worked instantly. No configuration needed. Latest firmware already installed. You will need to buy the BLUETTI P150D to P090D Cable separately to connect it to the AC500.

    • Good technology for energy-grid independence

      This was the 4th B300 I have purchased via Ebay. The install addition to the other 3 B300 was straight forward and the added battery capacity is already showing lower electrical line watts being consumed.
