PH1800 LV (3KW)

High Frequency Solar Inverter – 120V Output | Split Phase Capable (120/240V) | Parallel 3 Units | 450V PV Input

The PH1800 LV Series is a specialized 120V Output hybrid inverter designed for regions with 110V/120V grid standards (North America, Latin America). With a rated power of 3KW, it supports Parallel Operation of up to 3 units. A key feature is its ability to form a 120V/240V Split Phase system when two units are paralleled, making it capable of powering heavy 240V appliances. It combines a high-efficiency MPPT solar charger (up to 450V PV input on the 24V model) and a pure sine wave inverter in one compact package.

Key Features

  • Native 120V Output: Delivers reliable 110V/120VAC pure sine wave power, perfect for RVs, cabins, and homes in 120V grid regions.

  • Split Phase Capable (120V/240V): Supports connecting 2 units in parallel to create a standard 120V/240V Split Phase system, allowing you to run powerful 240V loads (like dryers and pumps) while balancing 120V lights and outlets.

  • Parallel Expansion: Supports parallel operation of up to 3 units, enabling a total system capacity of 9KW for growing power needs.

  • High Voltage MPPT (3024 Model): The 24V battery model surprisingly features a 450VDC Maximum PV Voltage, allowing for longer solar strings and simplified wiring compared to standard low-voltage inverters.

  • High Current Charging:

    • PH18-3024 LV: Up to 100A Solar Charge.

    • PH18-3048 LV: Up to 140A Maximum Total Charge (Solar + AC), ensuring rapid battery top-up.

  • Generator Compatible: Works seamlessly with diesel or gasoline generators to ensure continuous power during long outages.

Applications

  • North American RVs & Cabins: The 120V output and 450V PV input (24V model) are ideal for efficient off-grid living with limited roof space but high power needs.

  • Small Home Backup: Parallel two units to back up a standard US home panel (120/240V) during blackouts.

  • Latin American Markets: Perfect for 110V/120V countries requiring stable solar power with generator support.
