Victron Energy CMP121620000 MultiPlus C 12/1600/70-16 Inverter Battery Charger
Victron Energy MultiPlus C 12/1600/70-16 Inverter Charger
More power, faster charging the step-up 12V MultiPlus C for installations that demand more
The Victron Energy MultiPlus C 12/1600/70-16 (CMP121620000) is a high-output inverter and battery charger for 12V systems that need more than entry-level capacity can deliver. With 1300W continuous inverter output at 25°C (1200W at 40°C), a 70A three-stage battery charger, and a 3000W peak power capability, it steps up from the 1200VA MultiPlus C models to handle heavier loads, faster battery recovery, and more demanding installations while retaining the full PowerControl, PowerAssist, and UPS transfer functionality the MultiPlus range is trusted for.
Designed as a true worldwide product, the MultiPlus C 12/1600/70-16 suits caravans and motorhomes with high-draw 240V appliances, marine vessels requiring fast battery recharge between passages, off-grid cabins running multiple loads simultaneously, and backup power systems where a longer runtime under load is a priority. The 70A charger adjustable to 40A means a large 12V battery bank is brought back to full charge significantly faster than with lower-rated units, reducing generator run time and maximising solar absorption windows. Like all MultiPlus C models, it transfers to inverter output in under 20 milliseconds fast enough to be a true UPS for any connected load.
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: A meaningful step up from 1200VA models, the CMP121620000 handles heavier sustained loads microwave ovens, power tools, air compressors, larger inverter air conditioners and delivers 3000W peak for motor and compressor start-up inrush. Suitable for serious caravan, marine, and off-grid builds where a 1000W continuous rating leaves headroom too tight.
- 70A battery charger fast recovery: At 70A, this is one of the highest-output chargers in the compact MultiPlus C range. A 200Ah 12V battery bank depleted to 50% can be returned to near-full charge in under two hours reducing generator runtime, maximising the benefit of limited shore power windows, and ensuring the battery bank is ready for the next discharge cycle faster.
- Under 20ms UPS transfer no-break power: Shore or generator power lost? The MultiPlus C switches to battery-backed inverter output in under 20 milliseconds. Computers, CPAP machines, navigation systems, refrigeration controllers, and sensitive electronics all continue without disruption essential for liveaboards, off-grid cabins, and any installation where an outage causes real consequences.
- PowerControl intelligent load management: Set a maximum input current limit and the MultiPlus C manages the rest. It monitors all AC loads, allocates available capacity to charging, and ensures a small generator or limited shore supply is never overloaded automatically, without manual intervention.
- PowerAssist peak power boosting: When loads momentarily exceed what the shore or generator connection can deliver, the MultiPlus C draws from the battery to bridge the gap. Once demand drops, charging resumes. A compact generator handles peak loads it couldn't supply alone reducing the generator size and fuel consumption needed to run a fully-equipped installation.
- Dual AC outputs: Output 1 provides continuous no-break power to all connected loads. Output 2 is live only when AC input is present ideal for water heaters, battery chargers for other devices, and high-draw appliances that should never run from battery, automatically disconnecting them when shore or generator power is unavailable.
- Three-stage 70A charger with temperature compensation: Absorption (14.4V), float (13.8V), and storage (13.2V) charge stages extend battery life across all lead-acid chemistries. The included battery temperature sensor adjusts charge voltage automatically preventing overcharge in Australian summer heat and undercharge in cold conditions without any manual input.
- Parallel operation up to 6 units: Where more output is needed, up to 6 MultiPlus C units can be paralleled for significantly higher inverter and charging capacity. Three matched units support three-phase output scalable 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 minimal standby draw: AES mode reduces zero-load power to 5–8W; Search mode drops it further to 2–3W by sampling periodically for connected loads. Both modes extend battery runtime in lightly loaded or standby conditions important for full-time liveaboards and remote off-grid sites running on battery overnight.
- 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 options 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 12/1600/70-16 differ from the MultiPlus C 12/1200/50-16?
The 12/1600/70-16 delivers higher continuous inverter output (1300W vs 1000W at 25°C), a higher peak power rating (3000W vs 2400W), and a significantly larger battery charger (70A vs 50A). It suits installations with heavier loads or larger battery banks that benefit from faster recharge.
How quickly can the 70A charger recharge a depleted 12V battery bank?
At 70A, a 200Ah 12V battery bank at 50% state of charge can be returned to near-full in under two hours under ideal conditions. Actual charge time depends on battery chemistry, bank size, temperature, and available AC input current.
Does the MultiPlus C provide uninterrupted power during a blackout or generator cutout?
Yes. It transfers to battery-backed inverter output in under 20 milliseconds when AC input is lost fast enough that computers, medical devices, and sensitive electronics continue operating without any interruption.
Can PowerAssist allow a small generator to run loads beyond its rated capacity?
Yes. When loads briefly exceed generator output, PowerAssist instantly supplements from the battery to cover the shortfall. Once demand reduces, charging resumes. This allows a smaller, more fuel-efficient generator to run the same peak loads that would otherwise trip or overload it.
Does this product require a licensed electrician for installation?
Yes. The MultiPlus C 12/1600/70-16 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.
