Perfect for Tough Challenges

The combination of transformer-based technology and protection degree IP65 allows the inverter to be used in harsh enviroments, e.g. in locations near saltwater. When PV modules are used that need to be grounded, this inverter is the ideal choice. It not only supports negative and positive grounding, but also offers several monitoring methods.
The inverter can be used with input voltages up to 600 V and operating temperatures up to 70 °C. Gradual derating does not start before 55 °C.

Extended functionality

The inverter offers an extended MPP tracking function to improve the yield. For some countries powerful functions for controlling active and reactive power are available.
The comprehensive statistics as well as all messages about the current operating status and the complete life-time operating behavior can be read out on the easy-to-use display.
When the inverter is connected to a monitoring system - e.g. the Delta SOLIVIA Monitor 2.0, it can be supervised online.

Easy Installation

The simple on-display commissioning procedure guides the installer through all settings necessary to set up the inverter correctly. When an installation consists of multiple inverters of the same type, the settings of one inverter can be easily copied to the other inverters via the USB interface.
The inverter contains an integrated DC disconnector. A mounting plate and IP65 AC plug are included in the scope of delivery.

1) Cos Phi = 1 (VA = W)

2) Continuous nominal active power in the range of Cos Phi = 0.9 cap ... 0.9 ind

3) AC power can be limited at the inverter during commissioning to meet country-specific regulations regarding the maximum permissible grid load.

4) AC voltage and frequency range are programmed according to the individual country requirements.
