Maximum Profitability

The RPI M8A solar inverter features a 8 kVA power output. This new three-phase transformerless solar inverter is designed for residential or small commercial PV applications where maximum versatility and profitability are important. Thanks to the high maximum efficiency up to 98.3 %, 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 200 – 1000 V and 2 MPP trackers. 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 M8A greatly simplifies installation. The inverter includes a unique wall mount bracket in the scope of delivery, allowing the unit to be easily installed on a variety of wall surfaces.

Intelligent cooling design

The inverter uses an innovative heatsink design for cooling which draws the heat away from the inverter through a natural convection process. Because there are no fans required, maintenance costs are reduced and audible noise is greatly reduced. Additionally, the intelligent cooling design extends the life of electronic components and increases the life of the solar Inverter.
