Phocos 3kW Any-Grid Hybrid Inverter Charger

PSW-H-3KW-120/24V

The Phocos Any-Grid PSW-H-3KW-120/24V is a highly flexible 3,000W pure sine wave hybrid inverter charger designed for off-grid, grid-assisted, backup power, and self-consumption applications.

Featuring an integrated high-voltage MPPT charge controller and AC battery charger, the PSW-H delivers seamless energy management by intelligently combining solar power, batteries, utility power, and generator inputs.

Designed around a 24V battery architecture, the Any-Grid PSW-H can operate with or without batteries and can function as a traditional off-grid inverter, UPS backup system, or hybrid self-consumption solution.

Its rapid transfer capability, parallel expansion support, and integrated monitoring features make it an ideal energy platform for residential, remote, and backup power installations.
