PV350 PV800 MPPT solar pump inverter

The PV350 PV800 series solar pump inverter ( also can Solar Pump VFD) is a green energy products with new solar MPPT technology, which developed based on AD800 series motor VFD, focusing on driving 3 phase AC pumps including AC induction pumps or high efficiency pumps with permanent magnet synchronous motor (PMSM) technology.

Compare to on grid or off grid solar inverter, it has soft starter, and multiple functions of motor protection, and very high competitive price.

An arrays of solar panels generates the power and voltage required for the PV800 solar pump inverter to drive the AC pumps. The solar pump inverter converts the DC voltage input to a 3 phase AC output with variable voltage and frequency. The MPPT algorithm of solar inverter extracts maximum power available from the solar panels during the day and operates the motor at variable speed based on the power input to the inverter. The frequency range in which the inverter operates depends upon the motor speed, hydraulic system and the power available from the solar panel. As the sunshine varies during the day, power input to the inverter varies and the solar pump inverter generates variable V/F ratio thus controlling the speed of the motor, which in turn regulates the pump impeller speed. Water Level Sensor is used only when the water is pumped to overhead tank.

Product Features

PV series solar pump inverter general wiring diagram

Inverter connection

( Dual mode manual switchover, start/stop switch, AC/DC run mode switchover, water tank float ball sensor switch, well dry run switch, and GPRS controller...)

**Forbidden connect DC power supply to P+ and PB of PV350, otherwise it will cause serious damage.

Note:1. User use a switchover S to select AC grid or solar DC power source by manual.

2. Switch on S1 to start inverter when setting on external switch control mode, P0.01=1, and P5.00=1

3. Switch on S2 when connecting AC grid, make inverter work as normal VFD. set P5.02=51.

4. Connect 2 wires of float ball sensor to X4 and COM for water tank fulling detect, when water level reach to setting, the normal open switch of sensor will turn off to stop pumping, p5.03=54

5. Connect 2 wires of float ball sensor to X5 and COM on the well for dry run protection. P5.04=55.

If request to connect GPRS module controller, connect Vcc to 24vdc power supply, GND to COM, Txd to Rs485+, Rsd to Rs485-.
