Why Choose the MultiPlus?
-
All-In-One Power Management: Inverter, charger and AC transfer switch in one space-saving enclosure.
-
Scalable & Three-Phase Ready: Paralleling up to six units for higher output; configure three units for three-phase service.
-
Smart Load Sharing: PowerControl prevents overloads on shore or generator power by dynamically allocating excess capacity to battery charging.
-
Grid-Assist Capability: PowerAssist supplements weak shore or generator power with battery energy when demand spikes, then refills the batteries when load eases.
-
Ultra-Fast Charging: Four-stage adaptive charger tunes its algorithm to battery condition—bulk, absorption, float and a dedicated maintenance stage—plus a separate trickle-charge output for a second battery.
-
High Inrush Support: Delivers extra surge current for demanding loads like spotlights, welders or power tools.
-
Eco-Friendly Search Mode: Reduces idle inverter consumption by ~70%—automatically shuts down when loads are low and wakes every two seconds to check for demand.
-
Customizable Alarm Relay: Programmable dry-contact relay for alarms or system control (e.g., over-temperature, low battery).
-
Plug-And-Play & Fully Configurable: Basic settings via DIP switches; advanced tuning and firmware updates with VE-Config or VE.Bus Smart dongle.
-
Remote Monitoring & Control: Pair with a Cerbo GX (or other GX device) to view and adjust settings anywhere via Victron’s free VRM portal.
