PV Off Grid Solar Power System including:
Solar panel array, solar charge controller, storage battery, Off grid inverter, etc. In the sunshine, the solar panel convert the solar energy to DC power and charge the battery group by the charge controller. Then the off grid inverter convert the DC power into AC power for power supply the AC load. The newest Double Start Mode low frequency off grid inverter features: Our company combine user actual usage, specially designed this new low frequency off grid inverter, which is characterized by stable and reliable performance, set up parameters flexibly. It can meet different users different requirements, the characteristics as following:
- Two types of start mode: Step Down Voltage Start and Variable Frequency Start.
- The output frequency can be set.
- The output voltage can be set between -40 % to +20 % of rated voltage.
- The accuracy of output voltage is very high, usually no more than 1%.
- The DC input voltage range can also be set. Over-voltage point, under-voltage point, over-voltage recovery point , under voltage recovery point all can be set via the LCD panel.
- Convenient for increasing or reducing the quantity of batteries, photovoltaic modules also can be used flexibly.
- The under-voltage recovery time can be set.
- Pure sine wave output. with good transient response less than 50MS, little harmonic distortion, higher conversion efficiency and stable output voltage.
- Powerful data display and fault instruction function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.
- Using the fifth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function, the protection for short circuit, over load, over temperature is more safe and reliable. It's service life can up to 15 years or more. Wide input voltage can be set according to customer requirement. Input voltage range can be selected from 100-500v, 200-850v.
- Could add AC bypass input: Battery power priority (When battery power used out, it will automatically switch into AC bypass input) or Main power priority (when main power is down then the inverter will automatically switch to work from battery)
- The Inverter is suitable for areas without electricity, motor, marine, solar power system, wind power systems etc.
- Output AC Power is suitable for all types of home appliances, LED lamps, electric tools, electric motors etc.
- High conversion efficiency, Max. Efficiency 96%
- Adopts black pure aluminum radiator, which confirms the best radiating performance.
- Adopts low consumption anti-diode, even if wrong connection battery positive and negative pole, it won't be damaged.
- Adopts high quality fan, which could continuously work for 5 years and uninterrupted work for 20 years.
- Have passed the European CE (EMC and LVD) certificated and accredited by Australia CEC energy network.
