Mini 0.75kw 220V 240V Single Phase 90Vdc To 450Vdc Solar Pumping Inveter
Model:SG320-0K75GB-2S-M
SG320-mini size solar pump inverter hardware design
1. Input from top, output from bottom design
2. Independent air duct for good heat dissipation
4. Infineon/Fuji Igbt for 4T
Descriptions and Features
1.Solar pump inverter adopts advanced MPPT control technology, real-time detection of solar panels power voltage, tracking the highest voltage and current, efficiency is as high as 98%.
2.It can enter automatically to sleep mode when the intensity of sunlight is weak, as well as can exit the sleep mode when the intensity of sunlight is becoming strong.
3.Automatic sleep when on high-water level and automatic restart when on low-water level to realize automatic control through water level.
4.Multiple power supply design, power input can be solar energy photovoltaic DC power supply, can also
be single phase or three phase AC power, simple wiring.
5.Smart operation, water level detection and operation panel to prevent overflow, dry pumping.
6.Protect itself in trouble and improve the reliability of whole system.
7.LED display operating panel and support remote control,LCD display also available now.
Suggestion of driving single phase AC pumps:
Note: Please select bigger rated power of inverter for driving single phase pumps, because the
current of 1 220VAC phase pumps is bigger than 3 phase 220V AC pumps.
