PH1800 LV (3KW)

3KW Pure Sine Wave | 120VAC | 6000W Surge | Split-Phase Ready

The PH1800 LV Series is a flexible high-frequency on/off-grid solar inverter built for 120V homes, workshops and remote power systems. It delivers 3000W of pure sine wave output with 6000W surge power, providing stable electricity for appliances, pumps, tools and sensitive electronics. Available with 24V or 48V batteries, the inverter integrates MPPT solar charging, utility input and generator support in one compact wall-mounted design. Up to three units can operate in parallel for greater capacity, while two units can be configured as a 120V/240V split-phase system. Optional WiFi monitoring, CAN and RS485 communication simplify lithium BMS and generator integration, making the PH1800 LV suitable for expandable backup and off-grid applications.
