Product Details

ZUN sg600 solar pump inverter MPPT for AC pumps, DC pump inverter hybrid type solar pump drive

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.

SG600 solar pump inverter installation steps.

Wiring and commissioning
1. Connect DC power supply to P to P- (N) ( DC power supply also can wire to R, T , no need consider to polarity connection)
2. Check Voc input, if correct, switch one power.
3. Set motor parameters as pumps nameplate.
4. Confirmed the solar pump control mode and MPPT function mode. (PE-000=1)
5. Trail running with press RUN button to check running direction.
6. Set dry run function, lowest stop frequency, maximum current, flow PQ curve if need.
If need auto start and stop, you can select to terminals control with switch on X1 to COM.
a). DI1 and COM, (P4.00=1, forward running)
b), DI2 and COM, (P4.01=2, reverse running)
c), DI3 and COM, ( P4.02=53, solar control mode disable )
d), DI4 and COM, ( P4.03=51, digital signal of water leveling detect 1)
e), DI5 and COM (P4.04=52, digital signal of water leveling detect 2)
