Product Description

250W Grid Tie Micro Inverter

22-50V DC to AC 80-160V or 180-260VAC Pure Sine Wave Output

6-grade MPPT on grid inverter for 200-300W 30V 36V Solar Panel

Main Technical Highlights

1. Built-in High-precision Automatic Power Point Tracking:

Powerful MPPT algorithm can accurately capture and lock the maximum output power point by optimize the power collected from solar panels, which can make the power generation capacity increase more than 25%;

2. Reverse Power Transmission:
Reverse Power Transmission Technology, one of our patents. Inverters’ output power can firstly supply the load use, and surplus electricity can directly be transmitted into the power grid in the form of reverse direction, which can effectively use all output power from inverters, and make the power transmission more than 99%;

3. Full Digital Control:

Charging module uses intelligent soft-switch technology, built-in MCU; And inverter module uses high-frequency switching power supply technology and 32-bit DSP full digital SPWM control technology, with strong anti-jamming capability, computing speed, and high-degree intelligence, high quality of controlling accuracy and outpu waveform;

4. High-reliability Multiple Units Parallel Stacking:
Grid-tie Stacking Mode: inverters can be any multiple paralleled stacking for the grid-tie connection use;
Off-grid Stacking Mode: inverters can be also any multiple paralleled Stacking for the off-grid connection use, after the main monitoring system issues master signals, inverters receive signals and then sync ouput;

5. Electrical Isolation:
System input and output are both complete electrical isolation, also the whole distribution system has a very good insulation, which makes all isolated boosting circuit more secure and reliable;

6. Protection:
Over-temperature protection, under-voltage alarm, under-voltage protection, over-voltage protection, short-circuit protection, over-load protection, etc;

7. Simplify Maintenance Work (User can maintain by their own):
After the power station is installed, which almost doesn’t need make any maintenance work, after a long time, only needs to clear the dust from PV solar panels;

8. Flexible Installation:
Multiple inverters can be any stacking connected, which can be composed of single-phase parallel stacking system, which can also be composed of three-phase system to supply three-phase alternating current;

Installation of Micro Inverters

Step 1. Installation for fixed the inverter on the PV holder with the screws attached is as following:

Step 2. Connect the two DC terminal of the PV to the inverter, positive to positive, negative to negative. Show below:

Step 3. Open the waterproof cap on AC output side of the micro inverter, then plug to AC power line. Show below:

Step 4. Plug the AC output line to main AC cable;

Step 5. Repeat the fir st step to the third step to complete the installation of micro inverters;

Step 6. Finally, please connect the AC main cable to the utility grid to run renewable energy and saving $$$!
