Strengths
- Expandable with up to 6 B300K/B300S/B300 batteries per unit.
- Four 20A outlets plus NEMA TT-30R and NEMA 14-50R (120/240V).
- Dual 1,200W XT60 solar inputs (2,400W total, 12-60V).
- 3,840W Turbo charging reaches 80% in 45 minutes.
Watch out for
- No built-in USB or 12V ports; these require the separate Hub D1.
- 83.78 lb before adding batteries.
- 0ms UPS switchover needs the 240V setting and specific outlets; at 120V it is 20ms.
- Standard 15A AC charging port is limited to 1,800W.

Runtime = usable energy ÷ average draw. We count 85% of the rated 2,764.8 Wh as usable (2,350 Wh) to cover inverter and DC conversion losses. Fridges and freezers are averaged over their compressor cycle. An appliance runs only if its running watts fit the 3,840 W inverter and its start-up surge fits the 3,840 W surge rating. Wattages come from our appliance wattage table; try your own mix in the runtime calculator.
Which solar panels fit it?
- Solar input up to 2,400 W
- Voltage window 12–60 V
- Connector XT60
Recharge time is from empty with one panel in full sun: 2,764.8 Wh ÷ the lower of75% of the panel's rating or the station's solar input limit. A panel rated above the input limit is safe as long as its Voc fits, because the station only draws what it can take. MC4 panels need a standard MC4 adapter cable, which many stations include. Wiring two panels in series doubles the Voc, so check the total against the voltage window. Try any pairing in the solar panel matcher.
