What is the importance of off grid inverter?

The off grid inverter refers to the inverter capable of V / F control. Its outermost loop is the voltage loop, which can stabilize the voltage and frequency of the AC bus. The grid connected inverter can only inject rated power into the power grid for PQ control, which is not stable and can not control the voltage and frequency of the grid point. In terms of hardware structure, the DC side of off grid inverter is mainly a battery, which can provide continuous energy input for the system, while the DC input of grid connected inverter is usually volatile renewable energy such as photovoltaic or wind power generation.

What are the characteristics of off grid inverters?

1. It adopts a 16-bit single-chip microcomputer or 32-bit DSP microprocessor for control.

2. The PWM control mode greatly improves efficiency.

3. Use digital or LCD to display various operating parameters, and related parameters can be set.

4. Square wave, modified wave, sine wave output. Meanwhile, the off grid inverter output and its waveform distortion rate is less than 5%.

5. The voltage regulation accuracy is high, and the output accuracy is generally less than plus or minus 3% under the rated load.

6. It has a slow start function to avoid high current impact on the battery and load.

7. High-frequency transformer isolation, small size, and lightweight.

8. The off grid inverter is equipped with standard R232/485 communication interface, convenient for remote communication control.

9. It can be used in environments above 5500 meters above sea level.

10. With inlet packaging protection, inlet underrun protection, inlet voltage protection, outlet voltage protection, outlet overload protection, outlet circuit protection, overheating protection and other protective functions.

What do we need to do if we want to use an off grid inverter?

First, use the off grid inverter in strict accordance with the provisions of the user manual;

Secondly, the output voltage of the off grid inverter is 220 V AC, which is in a narrow space and a movable state, so be extra careful. It should be placed in a safe place to prevent electric shock. When not in use, it is best to cut off its input power supply;

Third, do not place the off grid inverter near the direct sun or the outlet of the heater. The working ambient temperature of the off grid inverter shall not exceed 40 ℃;

Fourth, the off grid inverter will generate heat when working, so do not place objects near or on it;

Fifth, be afraid of water. Don't let it get wet or sprinkle water.

What is the significance of installing off grid inverter?

Installing a Photovoltaic off grid energy storage system is more economical and environmentally friendly than using an oil engine for power generation. Compared with the grid connected system, the off grid system is more complex, and the user's load, power consumption, and local weather conditions need to be considered. In particular, the load conditions are diversified, including inductive load like water pump, resistive load like electric furnace, single-phase and three-phase. For the photovoltaic off grid system greater than 10kW, the mode of a single machine or multiple machines in parallel can be adopted.

The installation of off grid inverters can effectively solve some of the difficulties that occur in the process of using electricity. Shenzhen Sumry Electronics Co., Ltd. Has been committed to provide the perfect off grid inverters for every customer from all countries.
