Victron MultiPlus-II GX 6k5
All-in-one inverter/charger with local & remote monitoring, PowerControl/PowerAssist and options for on-grid/off-grid systems.
Why MultiPlus-II GX?
- Everything integrated : MultiPlus-II + GX device with 2×16 character display, USB, Ethernet, VE.Direct, BMS-CAN and Wi-Fi for visualization and control.
- Serious power : 4 kW (model 4k5) or 6 kW (model 6k5) continuous, with peak up to 7 kW / 11 kW (1 min).
- PowerControl & PowerAssist : limits or supplements AC current to protect fuses and cover consumption peaks.
- Parallel/three-phase operation : a single GX module is sufficient for parallel or three-phase systems.
- Remote monitoring via VRM (web & mobile app) and integration with MPPT solar controllers or PV inverter in hybrid topologies.
- High efficiency : up to 96%, low self-consumption (normal mode/AES/Load search).
- Battery compatibility : lithium, lead-acid, zinc-bromide and others (configurable profiles).
Typical applications
- Homes, caravans, boats: output for critical loads (“no-break”) and intelligent management of sources (grid, generator, PV).
- Off-grid or hybrid systems: optimized self-consumption with external current sensor (50 A / 100 A, optional).
- Commercial/industrial: integration into multi-unit systems and centralized monitoring.
