SG600 solar pump inverter MPPT for 1 phase pump control, pool pumps drive

The SG600 mini series solar pump inverter is a low voltage AC drive of 0.3 to 7.5 KW 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) withfast speed drop function
• The working voltage of solar panel can set by manual or MPPT automatically tracking
• Built in automatic sleep-wake up function, start by timer is option.
• Dry run (under load ) protection and well low level detect functio
• Motor maximum current 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
• LCD and LED display
• Low water probe sensor, and water level control function
• Driving for 1 phase pump
• Soft start for 1 phase AC pumps
• Lots of pumps protection
• suits for most 1 phase pool pumps or submiersible pumps

Solar pump inverter technical specification

Solar pump inverter models list

Solar pump inverter comissioning steps

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

4. 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.

5.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).

Solar panels selection ( voltage and how many PCS of solar panels)

Voc and Vmp selecting er pumps voltage.

Solar arrays selection tables as 1 phase 220V 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.
