3MW solar rooftops by our 20KW on-Grid solar inverters

3MW solar rooftops by our 20KW on-Grid solar inverters

The 3MW solar rooftops of several factories are powered by our 20KW on-Grid solar inverters only, total 150pcs COG20KTL 20KW on-Grid solar inverters! With smart communication and control, the total THD is still less than 3% of the 150pcs inverters! 


Coordinated control of dozens on-Grid PV inverters in parallel

Coordinated control of dozens on-Grid PV inverters in parallel

During the non-isolated/transformerless inverters in parallel, there is a direct coupling relationship between the inverter circuits, and distributed parameter impedance inside transmission lines.

100pcs 5KW on-Grid solar inverter shipped to Americas

100pcs 5KW on-Grid solar inverter shipped to Americas

Recently, we shipped 100pcs 5kw on-Grid solar inverters to Americas for L-L 220Vac Grid connections! With years sampling,testing and help from Brazil/Mexico/Chile/Peru customers, we solved problems caused by differences between Americas L-L power Grid and L-N 220Vac electricity Grid, for long time stable high-efficient Grid-connection working!
As well as some 1phase 120Vac 2KW-4KW&3phase 240Vac 10KW-30KW inverters.

Our MPPT Solar charge controller Running 1.5Year with 0 fault!

Our MPPT Solar charge controller Running 1.5Year with 0 fault!

Our MPPT Solar charge controllers 20A12Vdc to 65A 96Vdc  were installed in 2016 early at several Indian Ocean islands around Réunion for stand-alone solar power systems, bearing ocean corrective winds and moisture, But running 1.5Year until now without any fault! 
And half year before, we upgraded them to 3rd generation with outside-fuses/DC-loading/wider input voltage range/max efficiency!
