The GBC INV3-12-150-C inverter is a modified sine wave DC/AC converter that converts battery voltage into power for AC devices. It has a Schuko socket and a USB port, while SoftStart technology smooths the startup current of connected devices. It connects to the battery using alligator clips.

The aluminium housing dissipates heat through a built-in fan. The low-battery alarm and automatic shutdown in the event of under-voltage or over-voltage help protect the inverter and battery. It also has an internal fuse for short-circuit protection.
