Usability
7.1 out of 10It stores 5,222.4 Wh, in the upper band of the home tier below 6,000 Wh, so it scores 8 on capacity.
Its inverter is rated 7,200 W continuous with a 9,000 W surge and gives 240 V split-phase, so it scores 10 on power output.
FOSSiBOT states about 2.2 hours to full at 3,000 W on 240 V, which the US unit takes through its included 240 V cable (about 3.5 hours on 120 V), and 2,500 W of high-voltage solar, so it scores 7 on recharging.
FOSSiBOT rates the cells for 6,500 cycles to 80 percent, so it scores 10 on battery life.
It switches to battery in under 10 ms and takes two FB5222 batteries for 15,667 Wh, but FOSSiBOT sells no transfer switch, inlet box or panel for it, so it scores 5 on backup readiness.
