Overview

Maximum profitability

The RPI H3 solar inverter features a 3 kVA power output. This new single phase transformerless solar inverter is designed for residential PV applications where maximum versatility and profitability are important. Thanks to the high maximum efficiency up to 97 %, optimum yield from the PV plant is ensured from the device.

Flexible system design

For the system planner, maximum flexibility is ensured thanks to a wide input voltage range of 125 - 600 V. The new unit is compatible with major types of PV modules and the robust IP65 rated enclosure allows outdoor installation.

Simple installation

The lightweight and compact design of the RPI H3 greatly simplifies installation. The inverter includes a unique wall bracket in the scope of delivery.
