Microinverters CP-250E

CP-250E Microinverter


Chilicon Power CP-250E inverter performance leads the industry with sustained power production of 289 watts AC which provides well scaled output power compatibility for 60-cell and 72-cell modules up to 345W DC STC.  The CP-250E has extended input voltage range and supports 72-cell (CP-250E) modules. Grid-interactive conversion occurs with a CEC rating of 96% with peak efficiency of 96.6%. The inverters are Rule-21 compliant and can provide reactive power on demand. 

Reliability is provided through design that has all components rated to at least 200,000 hours service lifespan (or about 50 years of operating time). Firmware provides high frequency grid monitoring to ensure safe operation during any anomalous events. Surge protection to 6000Vac is integrated and the inverter enclosure and inputs are galvanically isolated from the grid connection to provide the ultimate safety barrier.

Magnetic component optimization and on-line adaptive switching techniques maximize efficiency and reduce cost. Chilicon inverters have been designed ground-up to provide reliability, efficiency, and lean construction to provide customers with the best possible inverter solution for their power generation project. 

The Power Line Communication (PLC) technology was developed from the ground up and offers the best robustness of any PLC system, vastly superior to the competition. It is so robust that the Gateway can be installed anywhere in the house. This saves on installation costs.
