Description
Interest in renewable energy has increased over the past few Years due to solar Power becoming more cost effective and eco-friendly. This is a solar inverter which allows power to be switched from the DC Power.
obtained from solar Panels to the AC Power needed to control the pump. with the renewable solar inverter, pumps can adapt to solar power sources rather than traditional electrical supplies or generators.
This solar inverter is built-in with MPPT Solar Charger to maximize solar power. Besides, it is easy to install with low maintenance cost. it is easy to install with low maintenance cost. It became an eco-friendly solution for the rural areas where grid power is expensive and unreliable.
Besides, this inverter also accepts single-Phase AC input. It allows the inverter to automatically switch between PV power and AC utility to guarantee water pump operation during night time.
Features
- Built-in MPPT Solar Charger
- Supports single-Phase asynchronous motor or three-phase asynchronous motor
- Built-in full protection and self-diagnosis
- soft start function prevents water hammer effect and extends system lifecycle
- Comprehensive LCD and LEDs Display real-time system status
- Remote Monitoring through RS-485
- Supports shingle-Phase AC input. When PV Energy is not sufficient, the inverters will automatically switch to AC inputs.
- Optional remote panel is available.
