Existing solar

AC couple an existing solar system

AC coupling retrofits this hybrid inverter onto an existing solar system.

The existing PV stays in place, and this inverter adds battery storage.

Generator

Store energy from a diesel generator

The inverter can store energy from a diesel generator in the battery.

That stored energy is available for later use.

Outdoor installation

IP65 enclosure

Ingress protection is IP65.

The communication interface is Wi-Fi, RS485 and CAN. The display is LCD and LED.

Monitor mode is GPRS, Wi-Fi, Bluetooth and 4G.
