MultiPlus-II 48/4k5 55-32 GX 230V omvormer-lader

Delivering 5000 VA of continuous inverter power at 230 VAC, the MultiPlus-II 48/4k5 55-32 GX 230V combines a pure sine wave inverter, a sophisticated battery charger, and an automatic transfer switch in a single compact enclosure. Its integrated GX functionality provides local and remote monitoring, control, and configuration via Ethernet, Wi-Fi, and Bluetooth.

Overview

Engineered for demanding off-grid and backup power applications, this MultiPlus-II unit accepts a DC input voltage range of 38–66 V and delivers a stable 230 VAC ±2% output at 50 Hz (60 Hz selectable). The built-in 50 A transfer switch ensures seamless switching between grid and inverter power, while the 70 A battery charger rapidly replenishes connected battery banks. With a peak efficiency of 95% and a zero-load power draw of just 20 W, it minimizes energy losses in both active and standby modes.

What stands out

• PowerAssist technology supplements limited grid or generator power with battery energy, preventing overload trips.
• Parallel operation of up to six units and three-phase capability of up to three units offer scalable power solutions.
• Integrated GX device with Color Control GX functionality enables remote monitoring, firmware updates, and system configuration via VRM portal.
• Dual AC outputs (AC Out 1 and AC Out 2) allow critical loads to be prioritized and non-critical loads to be shed automatically.
• Programmable relay and extensive communication ports (VE.Bus, VE.Direct, Ethernet, Wi-Fi, Bluetooth) provide flexible integration options.
