The electricity generated by the PV module is DC, and it cannot supply power to the AC load. The inverter needs to convert DC power into AC power and provide it to the load.
The inverter is used to convert DC energy (battery, storage bottle) into current (generally 220V, 50Hz sine wave). It consists of  inverter bridge, control logic and filter circuit. Inverter is a DC to AC transformer, which is actually a voltage inversion process with converter. The converter converts the AC voltage of the power grid into a stable 12V DC output, while the inverter converts the 12V DC voltage output by the adapter into high frequency high-voltage AC; Pulse width modulation (PWM) technology, which is widely used, is also used in both parts. Its core part is a PWM integrated controller, the adapter uses UC3842, and the inverter uses tl5001 chip.
 

1. Adopting multi-main shed (MBB) half-sheet technology, the output power   is away from 670W, and the conversion efficiency of the module reaches 21.57%.

2.   Anti-PID performance.   The PID (Potential Induced Degradation) resistance authority test(85°C/85% RH, 96 hours) under the harsh conditions of the industry minimizes the chance of degradation caused by the PID.

3.   12 main grid cell, with stronger current collection capacity and more stable power output.

4. Mechanical load. Certified for wind load of 2400 Pa at the back of the assembly and snow load of 5400 Pa at the front.
 

1. 100% fully automatic production line,ensuring 100%in-line inspection on the production line. Effectively avoiding the risk of hidden cracks and inherent defects.improving efficiency, reducing manual errors,precision welding,and maintaining uniform product quality standards.
2. First-class photovoltaic testing center, up to 38 valid tests and experiments to ensure product quality.
3. High, medium and low current classification to improve system output performance.
4. Two EL tests before and after.12-focus EL to overcome depth-of-field differences,spatial resolution of 0.4-0.5mm high and low currents are tested separately, with zero tolerance for quality risks.
5. Long-term reliability testing.The PV testing center follows the standard of 3 times thousand conventional tests to guarantee the longer life cycle of the modules.
