1200W MPPT Grid Tie Micro Inverter for Home Use Solar System 36V 220V or 110V, DC to AC 1200W Pure Sine Wave Power Inverter

(6-grade MPPT, also built in Power Line Carrier-current Communication)

Interview

WVC-1200 using IP65 waterproof streamline design, can effectively prevent rainwater on the surface erosion, built-in high-performance Maximum Power Point Tracking (MPPT) function, better able to track changes in the solar luminosity and control different output power, effectively capture and collect sunlight. AC electric power transmission using the reverse transmission technology, is one of our patented technology. The inverter output power can provid load priority use, extra electricity to the grid, efficient use of the inverter to the power emitted, electricity transmission up to 99%.

Communication using two modes, between the inverter and collector, using power line carrier communication signals, collector with a PC or other devices communicate, using RS232 serial port/WIFE wireless communication. Intelligent monitoring system, the inverter can collect real-time data, inverter can be controlled startup/shutdown/power regulation.

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;
