Victron Energy CMP122200100 MultiPlus C 12/2000/80-50 120V Inverter Battery Charger
Victron Energy MultiPlus C 12/2000/80-50 Inverter Charger
The high-output 12V MultiPlus C 2000VA inverter, 80A charger, and PowerAssist for installations that demand the most
The Victron Energy MultiPlus C 12/2000/80-50 (CMP122200100) is the highest-output model in the compact MultiPlus C 12V range, stepping up to 2000VA and 1600W continuous inverter output at 25°C (1400W at 40°C) with an 80A three-stage battery charger and a 4000W peak power rating. Built for installations where a 1200VA or 1600VA unit simply isn't enough, it delivers the sustained output and fast battery recovery that serious caravans, vessels, off-grid cabins, and backup power systems require.
At 80A, the charger is one of the most capable in the compact MultiPlus C series returning a large 12V battery bank to full charge significantly faster than lower-rated models, reducing generator runtime, and making the most of limited shore power windows. Combined with PowerControl for smart input management, PowerAssist for peak power boosting from the battery, and sub-20ms UPS transfer, the MultiPlus C 12/2000/80-50 is a complete power management solution in a single unit. Designed as a true worldwide product, it operates on 230VAC output across the full 187–265VAC input range suited to Australian shore power, generators, and grid supplies without modification.
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
- 2000VA / 1600W continuous 4000W peak: The most powerful model in the compact MultiPlus C 12V range. At 1600W continuous (1400W at 40°C) and 4000W peak, it runs high-draw appliances air conditioners, induction cooktops, power tools, washing machines and handles heavy motor start-up inrush that would overwhelm smaller units. For installations where 1600VA left insufficient headroom, this is the answer.
- 80A battery charger fastest recovery in the range: At 80A, this is the highest charge current available in the compact MultiPlus C 12V lineup. A 300Ah battery bank depleted to 50% can be returned to near-full in under two hours under optimal conditions maximising the value of every hour of generator runtime or available shore power, and ensuring the battery bank is ready for the next cycle faster than any lower-rated model in the range.
- Under 20ms UPS transfer true no-break power: Shore or generator input lost? The MultiPlus C switches to battery-backed inverter output in under 20 milliseconds seamlessly enough that computers, CPAP machines, medical devices, refrigeration controllers, and navigation systems continue without interruption. For liveaboards, remote off-grid sites, and any installation where an outage has real consequences, this transfer speed is non-negotiable.
- PowerControl intelligent input management: Set a maximum input current limit and the MultiPlus C takes care of the rest. It monitors all AC loads, calculates available headroom in real time, and allocates spare capacity to battery charging ensuring a small shore supply or generator is never overloaded regardless of how loads fluctuate throughout the day.
- PowerAssist peak power on demand: When loads momentarily exceed what the shore or generator connection can supply, the MultiPlus C draws instantly from the battery to bridge the gap. Once demand subsides, it seamlessly returns to charging. A lighter, more fuel-efficient generator handles peak loads it couldn't support alone a significant practical benefit for caravans and vessels where generator size and weight matter.
- Dual AC outputs: Output 1 provides continuous no-break power to all connected critical loads. Output 2 is live only when AC input is present water heaters, battery chargers for other devices, and non-essential high-draw appliances can be wired here and automatically shed when shore or generator power is unavailable, preventing unnecessary battery drain.
- Three-stage 80A charger with temperature compensation: Absorption (14.4V), float (13.8V), and storage (13.2V) charge stages protect 12V battery health and extend cycle life across all lead-acid chemistries. The included battery temperature sensor adjusts charge voltage automatically for ambient conditions preventing overcharge in Australian summer heat without manual adjustment.
- Parallel operation up to 6 units: Where even more output is needed, up to 6 MultiPlus C units can be paralleled for higher inverter and charging capacity. Three matched units support three-phase output, scaling from a single installation to a large commercial or industrial off-grid system.
- 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 controlled standby consumption: AES mode reduces zero-load draw to 7–9W; Search mode drops it to 3–4W. Both modes meaningfully extend battery runtime in lightly loaded or overnight standby conditions important for full-time liveaboards and remote off-grid sites where overnight battery draw adds up.
- 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 12/2000/80-50 differ from the MultiPlus C 12/1600/70-16?
The 12/2000/80-50 delivers higher continuous inverter output (1600W vs 1300W at 25°C), a higher peak power rating (4000W vs 3000W), and a larger battery charger (80A vs 70A). It is the top-output model in the compact MultiPlus C 12V range, suited to installations running high-draw appliances or large battery banks requiring faster recharge.
How quickly can the 80A charger recover a large 12V battery bank?
At 80A, a 300Ah 12V battery bank at 50% state of charge can be returned to near-full in under two hours under optimal conditions. Actual charge time depends on battery chemistry, bank size, temperature, and available AC input current but the 80A rating makes this the fastest-charging compact MultiPlus C 12V model available.
Does the MultiPlus C 12/2000/80-50 provide uninterrupted power during a blackout?
Yes. It transfers to battery-backed inverter output in under 20 milliseconds when AC input is lost fast enough that computers, CPAP machines, medical devices, and sensitive electronics continue operating without any interruption.
Can this unit run an air conditioner or induction cooktop from battery?
It depends on the appliance's power draw and your battery bank capacity. The 4000W peak rating handles most air conditioner and induction cooktop start-up inrush, and the 1600W continuous rating (1400W at 40°C) sustains moderate steady-state loads but runtime from battery will depend on battery bank size and state of charge. Consult your installer for a full load assessment.
Does this product require a licensed electrician for installation?
Yes. The MultiPlus C 12/2000/80-50 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.
