This document is a user manual for the ONE-SOLAR Hybrid Solar Inverter, models HSI-2KVA to HSI-6KVA, manufactured by FOSHAN TOP ONE POWER TECHNOLOGY CO., LTD.
Function Description
The ONE-SOLAR Hybrid Solar Inverter is designed to convert DC power from solar panels and batteries into AC power for various loads. It supports both MPPT (Maximum Power Point Tracking) and PWM (Pulse Width Modulation) charging modes, offering flexibility in solar panel configuration. The inverter can operate in different modes, including:
- Normal Mode: AC input prioritizes supplying the load and charging batteries; batteries supply loads without AC input.
- Saving Mode: AC input is advanced to supply the load and battery, with batteries supplying loads without AC input. This mode requires the load to be greater than 5% of the inverter capacity; otherwise, the machine will continuously start up and shut down.
- Battery Mode: Battery prioritizes supplying the load. When the battery power or voltage is low, it automatically switches to AC mains supply. Once the battery is fully charged, it transfers back to battery supply.
The inverter features an LCD panel for displaying operational data and settings, and includes various protection mechanisms to ensure safe and reliable operation.
