250W grid connected microinverter for solar power system

  250W grid connected microinverter for solar power system

Product Description

 

Features of Smart Microinverter

1. Unique circuit design, choice of import industrial electronic components, higher efficiency, more stable performance.

2. Creative MPPT technology, efficiency more than 99%, faster and more sensitive reaction, more reliable.

3. Parallel type design for DC input and modularization design for inverter, small volume, distributed installation, easy for system configuration, flexible for combination, strong expansibility of system.

4. Adopting high-frequency isolation transformer type, high efficiency, and high security.

5. Perfect electrical protection function.

6. Aluminum alloy housing, not rust, heat-resisting and cold-resistant as well as anti-corrosion.

7. Getting electronic circuit design, appearance design and other core technology patents.

8. High-quality thermal conductivity silica gel potting in, electronic components completely isolated from the air and it makes the aging of electronic components almost stop, greatly enhancing the life time of the product.

9. Highly DSP (Digital Signal Processor) as well as precision sensor IC adopted for getting accurately electrical parameters. Work with data sender and data collector to achieving remote monitoring, so the solar power generation information you can get and monitor at anytime and anywhere.
