SG600 Solar pumps inverter MPPT solar pump controller , 220V/380V solar pump drive

The SG600 series solar pump inverters is a low voltage pumps inverter of 0.3 to 400KW above rating designed to operate with energy drawn from solar panel or photovoltaic cells (PV).

The inverters is customized to operate in dual supply mode (Ac and DC), so the grid connected supply is used in the absence of energy from PV cells. This drive functions with the latest in technology maximum power point tracking (MPPT) algorithm to derive maximum power from the PV cells at any instant.

SG600 solar pump inverter features.

The SG600 series solar pump inverter is a low voltage AC drive of 0.3 to 400KW above rating designed to operate with energy drawn from solar panel or photovoltaic cells (PV).

The inverter is customized to operate in dual supply mode (AC and DC), so the grid connected supply is used in the absence of energy from PV cells. This inverters functions with the latest in technology maximum power point tracking (MPPT) algorithm to derive maximum power from the PV cells at any instant.

• Maximum power point tracking (MPPT) with fast response speed and stable operation efficiency > 99.6%;
• High speed running when sunlight radiation is good, frequency reduce fast when sunlight is become weak, stop running when output frequency lower lower limit frequency setting.
• Suits for most 3 phase AC pumps and AC PMSM high efficiency pumps.
• The working voltage of solar panel can set by manual or MPPT automatically tracking
• Compatible with dual power input, AC grid and DC power supply input.
• Built in automatic sleep-wake up function, start by timer is option.
• Dry run (under load ) protection
• Motor maximum current protection
• Low input power protection
• Lowest stop frequency protection
• The PQ (power/flow) performance curve enables calculating the flow output from the pump
• Digital control for fully automatic operation, data storage and protective functions
• Intelligent power module (IPM) for the main circuit
• LED display operating panel and support remote control
• Low water probe sensor, and water level control function
• Strong lightning protection
• Easy operation and CVT auto detection function
• GPRS function is option for remote start and stop, remote parameters setting.

 Solar pump inverter models and specification

Solar pump inverter technical specification

Solar pump inverter comissioning

It is accepted dual power AC/DC mode connecting input. If connect AC and DC at the same time, please install a anti direction diode (protection diode) between inverter and soalr panels which used to protection solar panels safety.

User can able to install a power switchover to selection which mode power input as conditions.

1. Wiring DC power supply to R, T terminals of inverter. ( or connect P P- termianls as well) 

2.Check actual Voc ( open loop circuit voltage) of solar arrays by multi-meter, or monitor U012 parameters that display Voc value in keypad. Set PE-03 with actual Voc value.

3.Confirmed PE-00 if set for 1or 2 for MPPT working in solar pump control model.

4. Set P1-00 to P1-05 motor group parameters for getting better pumps protection.

5. Press the RUN button to start inverter (keypad control mode is in default setting, P0-02=0),to check output frequency, output voltage if good or not. The output frequency should be increase from 0 to 50/60hz, and output voltage should be balanced when frequency reach to rated frequency of pumps.

6.If output frequency and output voltage is normal, please stop inverter, and then switch off power, after that connect pump to U, V, W of inverter. ( connect U, W for 1 phase pumps).

7. Press the RUN to start inverter to check water flow if correct, if water flow is small when reach to high speed, please check the pump running direction if correct or not. Please rewire any two phase order of U, V, W if pump running direction is not correct.

Solar panels selection 

Voc and Vmp selecting er pumps voltage. 

Solar arrays selection tables as AC pumps.

Connecting solar panels in series to get enough voltage input, and then calculating how much strings for getting enough power.

Take a solar panels Voc38VDC, Vmp 31VDC, 265W for exampling.

Please check if enough DC voltage input for system, Voc and Vmp. 2S (310vmp), 380V (540vmp).

If the output frequency is not high, lower than 50/60Hz even in good sunlight radiation, please check if enough solar panels have been connected. The total power should be at least bigger 1.3 times than of rated power of pumps.
