Product Introduction

Product overview

Area of application

Due to their compact dimension and low noise generation, the inverters are particularly suitable for the use in private and small commercial installations in residential and office buildings. They can be used indoors and outdoors (IP65).

Grid connections made easy

The inverters are certified according to VDE-AR-N 4105. A 5-pin plug for grid connection is supplied.

Optimized module connectivity for maximum performance

Two (M6A, M8A) or three (M10A) module strings can be connected to the inverters and can be controlled independently of each other. The mechanical AC/DC disconnector disconnects the inverters from the grid and from the modules. The required DC plugs are included in the scope of delivery.

Fanless cooling

Heat is exchanged with the environment via natural convection, which makes the inverters very quiet during operation.

Convenient operation

Setting up and commissioning can be carried out conveniently via the display or using the DeltaSolar app. The system can be monitored locally with the app or online in the MyDeltaSolar Cloud (registration required). The Wi-Fi antenna can also be used to connect the inverters to a wireless router.
