The Victron MultiPlus-II 24/3000/70-32 combines an inverter, battery charger and AC transfer switch in one unit for 24V battery systems. It delivers 3000VA of continuous inverter output, a 70A multi-stage battery charger and a 32A AC transfer switch, making it a single battery charger with inverter for off-grid, backup and mobile power setups.

Key features

• Inverter output, 3000VA continuous, 24V DC in, 230V AC out.
• Battery charger, 70A multi-stage charging with an adaptive algorithm suited to different battery chemistries.
• AC transfer switch, 32A rating with a transfer time under 20 milliseconds, keeping connected loads powered through grid or generator switching.
• PowerAssist, draws extra power from the battery when AC input is limited, reducing the risk of tripped breakers or an overloaded generator.
• Dual AC outputs, AC-Out-1 stays live during inverter operation; AC-Out-2 disconnects on battery power so non-essential loads can be shed automatically.
• VE.Bus communication, connects to Victron GX devices for monitoring, parallel operation and configuration via VEConfigure.

Applications

Suited to off-grid cabins and homes running a 24V battery bank, backup power for commercial or agricultural buildings, and marine or narrowboat systems that need 230V AC from a 24V supply. It also fits mobile and vehicle-based builds, and hybrid systems that combine solar, battery storage and a grid or generator connection. Multiple units can be run in parallel or configured for three-phase output where a system needs to scale.
