Growatt, Kinglong and CEHE transformer and transformerless inverters

Power Protection inverters include Growatt, Kinglong and CEHE inverters, both transformer and transformerless systems in power outputs to 1000 kW.

The Growatt solar inverters range in power from 1500 to 17,100 W with single- and three-phase outputs. For higher ratings, two MMPTs are available per inverter suitable for 2 plus 2 strings for ratings of 3.6, 4.2 and 5 kW. DC to DC conversion efficiency (MMPT efficiency) is 99.5%. The CEHE inverters have outputs to 1000 kW.

The Growatt inverters, with high-energy density solid-state components, are transformerless and do not have fans, relying on convection-promoting designs. IP65-rated electronics provide protection against ingress of dust or powerful water jets and the inverters can be operated in ambient temperatures to 60°C.

The CEHE grid-tied solar inverters have outputs ranging from 1800 W to 1000 kW, meet specifications including VDE and TÜV, use IGBT switching technology and feature good islanding protection.

The Kinglong grid-tied transformerless and fan-less inverters are available in single-phase ratings to 5 kW. They feature RS485 communication, allowing the building up of both two- and three-phase systems, using two and three inverters.
