Low-voltage off-grid storage systems

USASP Series 120/240V Split-Phase Hybrid Solar Power Station

USASP is selected first by its 120/240V split-phase architecture, not by a country label. Compatible projects can then match 5.5 or 6.2 kW output with 6.4–19.2 kWh battery storage.

Questions before quotation

Is USASP intended for standard 230V single-phase projects?

No. The defining specification is 120/240V split-phase output, so it should not be treated as a default substitute for 230V single-phase systems.

Can USASP connect to the grid?

Current data states that grid-connected AC output is subject to local regulations. The project location and installation design must be reviewed.

Which USASP battery capacities are listed?

Current configurations include 6.4, 12.8 and 19.2 kWh battery options.
