Victron Energy MultiPlus C 24/1600/40 Inverter Charger

High-output 24V inverter and charger more power, smarter load management, built for demanding installations

The Victron Energy MultiPlus C 24/1600/40 (CMP241620000) is a high-output inverter and battery charger for 24V systems that need greater continuous power and faster charging than entry-level models provide. Delivering 1300W continuous inverter output at 25°C (1200W at 40°C), a 40A three-stage battery charger, and a 3000W peak power capability, it handles the heavier loads and larger battery banks common in serious off-grid, marine, and commercial backup installations running on 24V architectures.

The 24V platform brings practical advantages over 12V at this power level smaller cable cross-sections for equivalent current, lower resistive losses over longer runs, and better suitability for larger battery banks where a 24V nominal voltage is already the foundation of the system. Combined with Victron's PowerControl and PowerAssist technologies, the MultiPlus C 24/1600/40 becomes an intelligent power hub that manages shore or generator input, boosts peak load capacity from the battery, and transfers to battery-backed inverter output in under 20 milliseconds when AC input is lost making it a true UPS for any connected load. Suited to caravans, motorhomes, vessels, off-grid cabins, and commercial backup installations across Australia.

Important: This product must be installed by a licensed electrician. It involves mains AC voltages and connection to shore power, generator, or grid supply.

Features & Benefits

• 1600VA / 1300W continuous 3000W peak: Handles sustained high-draw 240V loads that lighter inverter chargers can't sustain microwave ovens, power tools, air compressors, and multiple appliances running simultaneously. The 3000W peak rating covers motor and compressor start-up inrush without tripping the unit, giving headroom where budget-tier inverters fall short.
• 24V platform advantage at 1600VA: At this output level, a 24V system draws half the input current of an equivalent 12V system meaning smaller, lighter, and cheaper input cabling, lower resistive losses, and less voltage drop across long cable runs. The CMP241620000 is the natural choice for any serious off-grid or marine installation already built around a 24V battery bank.
• 40A three-stage battery charger: Full absorption (28.8V), float (27.6V), and storage (26.4V) charge stages maintain 24V battery health and maximise cycle life. A separate 4A output simultaneously maintains a 24V starter battery. The included battery temperature sensor adjusts charge voltage automatically for Australian conditions no manual intervention required.
• Under 20ms UPS transfer no-break power: When shore or generator power is lost, the MultiPlus C switches to battery-backed inverter output in under 20 milliseconds. Computers, navigation systems, CPAP machines, refrigeration controllers, and sensitive electronics continue operating without interruption essential for liveaboards, remote off-grid cabins, and any installation where an outage matters.
• PowerControl smart load management: Set a maximum AC input current limit via the Multi Control Panel and the MultiPlus C manages the rest. It monitors all connected AC loads in real time, allocates remaining capacity to battery charging, and prevents the shore supply or generator from being overloaded automatically, as loads change throughout the day.
• PowerAssist peak power from the battery: When loads briefly exceed what the shore or generator connection can deliver, the MultiPlus C draws from the battery to bridge the gap instantly. When demand drops back, charging resumes. A smaller, lighter generator can run loads it couldn't handle alone reducing generator size, weight, and fuel consumption for mobile and remote installations.
• Dual AC outputs: Output 1 delivers continuous no-break power to all critical connected loads. Output 2 is active only when AC input is present water heaters, high-draw appliances, and non-essential loads can be wired here to prevent unnecessary battery discharge when shore or generator power is unavailable.
• Parallel operation up to 6 units: Where higher output is needed, up to 6 MultiPlus C units can be paralleled for greater inverter and charging capacity. Three matched units support three-phase output, with up to 6 three-unit sets paralleled for very large off-grid or industrial systems.
• Solar and grid-interactive capable: Supports off-grid PV, grid-connected self-consumption, and grid-interactive applications via Victron's Assistant software framework. Loss-of-mains detection available for compliant grid-tie configurations.
• AES and Search modes low standby draw: AES mode reduces zero-load power consumption to 5–8W; Search mode drops it to 2–3W. Both modes extend battery runtime significantly in lightly loaded or overnight standby conditions valuable for full-time liveaboards and remote off-grid sites.
• Full Victron monitoring ecosystem: Compatible with Battery Monitor, Multi Control Panel, Color Control GX, Cerbo GX, and the free Victron VRM remote monitoring portal. Bluetooth Smart, USB, RS232, and Ethernet connectivity available via compatible accessories.
• DIP switch configuration for stand-alone use: Basic settings adjusted in minutes without a laptop. Parallel and three-phase configurations use VE.Bus Quick Configure or VE.Bus System Configurator software.

Frequently Asked Questions

How does the MultiPlus C 24/1600/40 compare to the 24/1200/25 model?

The 24/1600/40 delivers higher continuous inverter output (1300W vs 1000W at 25°C), a higher peak power rating (3000W vs 2400W), and a larger battery charger (40A vs 25A). It suits installations with heavier loads or larger 24V battery banks that benefit from faster recharge and greater sustained output.

Why choose a 24V model over the equivalent 12V MultiPlus C?

At 1600VA output, a 24V system draws half the input current of an equivalent 12V system. This means smaller, lighter input cabling, lower resistive losses, and less voltage drop across long cable runs making the 24V platform more efficient and cost-effective for larger builds and installations with extended wiring runs.

Does the MultiPlus C provide uninterrupted power if shore or generator power fails?

Yes. It transfers to battery-backed inverter output in under 20 milliseconds when AC input is lost fast enough that computers, medical devices, navigation systems, and sensitive electronics continue operating without any interruption.

Can PowerAssist allow a smaller generator to run loads beyond its rated capacity?

Yes. When loads briefly exceed generator output, PowerAssist instantly draws from the battery to cover the shortfall. Once demand reduces, charging resumes automatically. A smaller, more fuel-efficient generator can handle the same peak loads that would otherwise trip or overload it.

Does this product require a licensed electrician for installation?

Yes. The MultiPlus C 24/1600/40 connects to mains AC voltages shore power, generator, or grid supply and must be installed by a licensed electrician in accordance with Australian electrical standards. Do not attempt self-installation.
