Growatt solar inverter range

A range of PWM, high-frequency, lightweight, transformer-based Growatt solar inverters ranging in power from 2100 to 3170 W is available.

The inverters are suitable for full galvanic-isolation connection to single-phase LV grids. The ratings available are 2100, 2600 and 3170 W.

The inverters incorporate the latest developments in high-energy-density solid-state components, weigh 17 kg. The inverters offer IP65 electronics with protection against ingress of dust or powerful water jets. They can be operated in ambient temperatures to 60°C.

Safety is via DC reverse polarity protection, ground fault monitoring, grid monitoring (allowing correct restart after power failure of the grid) and leakage current monitoring.

The inverters use H4 switching with four switches to create low distortion AC with a THD of less than 3%, at high conversion efficiency to 95.5%.

The inverters are equipped with Bluetooth, making them suitable for operation in future smart grid developments.
