Sixteen kilowatt-hours of independence.
The flagship tower pairs a 5.5kVA hybrid inverter with 15,974Wh of 51.2V LiFePO4 storage — enough to run a whole home overnight and recharge from a 5kW solar array the next day. Same plug-and-play format: wheeled in, terminals connected, system running.
15,974Wh covers a full day of typical household consumption including cooking and climate, at 5.5kVA concurrent output.
The wide 120–450VDC MPPT window accepts up to 5,000W of PV — full battery recharge in a single sunny day.
High voltage halves battery current versus 24V: cooler operation, lighter cabling, higher round-trip efficiency at high load.
Graded overload (130%/5s), short-circuit switch, and full battery protection with RS485 communication and sleep mode.

For most homes it is the practical off-grid threshold: one day of full autonomy plus a 5kW array for recharge. Heavy air-conditioning or electric heating loads may warrant pairing a second unit or station.
Voltage and capacity: the 24V/3.5kVA/7,987Wh model suits essential-load backup; the 51.2V/5.5kVA/15,974Wh model doubles energy and output for whole-home use. Both share the plug-and-play wheeled format.
The battery module weighs 115.9kg — the tower rolls on swivel casters for positioning and is meant to be installed once. Two-person handling is required for stairs or thresholds.
