Delta RPI H4A

Maximum profitability

The RPI H4A solar inverter features a 4 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 97.5 %, 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 100 - 550 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 H4A greatly simplifies installation. The inverter includes a unique wall bracket in the scope of delivery.

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.
