PV3900 (8-12KW)

Low Frequency Solar Inverter – Split Phase Transformer | 200A MPPT | Heavy Duty Motor Start | Off-Grid System

The PV3900 Series is a heavy-duty Low Frequency Solar Inverter engineered for the most demanding off-grid environments. Unlike high-frequency models, this beast features a massive built-in copper transformer, providing superior reliability and surge capacity (3x rated power) to effortlessly start heavy inductive loads like air conditioners, water pumps, and compressors (up to 6HP). With a massive 200A MPPT solar charger and 10KW PV input capability, it is the ultimate power station for large villas, farms, and industrial backup.

Description

Key Features

  • Robust Low Frequency Design: Built with a heavy-duty transformer, it offers exceptional shock resistance and stability, making it ideal for powering sensitive and heavy inductive loads that would trip standard inverters.

  • Massive 200A MPPT Charging: Features a high-current 200A MPPT solar charge controller, supporting a maximum PV array power of 10000W, ensuring rapid battery charging even with large battery banks.

  • Extreme Surge Capability: Delivers a 300% surge rating (up to 36KW on the 12KW model), allowing it to handle peak startup currents of heavy motors (4HP-6HP) without breaking a sweat.

  • Smart Hybrid Charging: Combines solar and utility charging with a Maximum AC Charge Current up to 140A, ensuring your batteries are always ready, rain or shine.

  • Expandable Capacity: Supports parallel operation of up to 3 units, enabling you to scale your system power up to 36KW for larger energy needs.

  • Generator & Lithium Friendly: Fully compatible with diesel generators and features diverse battery settings (Lead-acid, Gel, Lithium) with BMS integration.

Applications

  • Heavy Motor Loads: Perfectly suited for water pumps, large refrigerators, air compressors, and AC units that require high starting torque.

  • Remote Estates & Farms: Reliable power for large off-grid properties running agricultural equipment or workshops.

  • Unstable Grid Areas: Acts as a fortress against voltage spikes and dirty power, protecting your household appliances.
