Product Details
The MultiPlus Compact 12/2000/80-30 is a three-in-one inverter, charger, and automatic transfer switch in a single aluminium enclosure. It inverts 12V DC to 2000VA of pure sine wave 230V AC, charges your battery bank at up to 80A, and switches between shore/generator power and inverter power in under 20 milliseconds — fast enough that connected equipment never knows the source changed.
The step from the 1600VA Compact model to this one matters more than the VA number suggests. The 30A transfer switch on this unit handles up to 6,900W of AC passthrough — nearly double the 3,680W ceiling of the 1600VA model's 16A switch. On a marina berth, at a caravan park pedestal, or with a generator running parallel loads, that headroom is real and frequently used. The 80A charger (up from 70A) gets a flat battery bank back to charge meaningfully faster when you're on shore power and want to get back off it.
The "Compact" label refers specifically to the 125mm mounting depth, not to the overall unit. At 520mm tall, 255mm wide, and 12kg, this is a substantial unit. What the form factor solves is depth-constrained installation spaces — the kind found in Australian caravan battery compartments, marine battery lockers, and van conversion side panels where wall depth from stud to face is limited. If depth is your constraint, this is the unit. If it is not, the standard MultiPlus 12/2000/80-32 covers the same electrical ground in a shorter, lighter package.
Key Features
- 2000VA / 1600W pure sine wave output at 25°C — 1400W continuous at 40°C. Plan your load calculations around the 1400W figure for enclosed Australian installations in summer conditions.
- 4000W peak (surge) output. Handles motor start loads, induction cooktops, and short-duration high-demand appliances that would stall lesser units.
- 80A adaptive 4-stage battery charger. Runs bulk, absorption, float, and storage stages. Adaptive absorption adjusts automatically based on previous charge history — prevents both sulphation and overcharge. Battery temperature sensor included.
- 30A automatic transfer switch. Switches between AC input (shore or generator) and inverter output in under 20ms. Transparent to computers, networking equipment, and sensitive electronics. This is the single most important difference between this model and the 1600VA Compact below it.
- PowerAssist and PowerControl. Set an AC input current limit; the unit draws up to that limit and supplements from the battery when loads exceed it. Shore power trips become a configuration issue, not a capacity problem.
- VE.Bus interface. Connects directly to Cerbo GX, Ekrano GX, and other Victron GX devices for full system monitoring, VRM cloud portal access, remote configuration, and multi-unit parallel or three-phase setups.
- Wide AC input tolerance: 187–265V AC, 45–65Hz. Handles generator voltage sag and the variable output common at long caravan park cable runs without faulting.
- ECE R10-4 automotive electromagnetic certification. The unit is qualified for vehicle and marine vibration environments — not just CE-marked office electronics in a blue box.
- LiFePO4 compatible. Charge profile must be configured via VEConfigure software using an MK3-USB adapter, or managed by a compatible BMS. Factory defaults are set for lead-acid — do not assume plug-and-play with lithium.
- 5-year Victron warranty, extendable to 10 years. Supported through authorised Australian dealers.

PowerAssist and PowerControl — How They Work in Practice
Both functions address the same root problem: your AC source has a hard current limit, your loads do not respect it, and tripping the breaker is unacceptable.
PowerControl is the simpler of the two. You set a maximum AC input current limit — say, 16A for a standard caravan park pedestal — and the MultiPlus treats that as a ceiling. When the battery charger is running at full draw and you switch on a high-load appliance, the charger reduces its current automatically to keep total AC input within the 16A limit. The park supply stays live. The battery charges more slowly for a while. That is the trade-off, and it is the correct one.
PowerAssist goes further. Consider a 32A pedestal connection shared across a busy marina. The site management limits individual berth supplies to 16A. You have the 16A shore feed passing through the MultiPlus's 30A transfer switch. You run the air conditioning (10A), the battery charger (6A), and then decide to run the electric kettle (10A) — 26A total demand. Without PowerAssist, the kettle trips the breaker. With PowerAssist, the MultiPlus draws its full 16A from shore and supplements the remaining 10A from the battery bank in real time. The kettle runs. When the kettle turns off, the excess shore capacity goes straight back into the battery.
This is where the 30A transfer switch matters practically. The 16A switch on the 1600VA Compact model caps shore passthrough at 3,680W regardless of PowerAssist settings. The 30A switch on this unit allows up to 6,900W of AC passthrough, which means the inverter's full 2000VA capability is usable in concert with a properly rated shore connection without the transfer switch becoming the limiting factor.
Installation Notes
- Battery cables. The included 1.5m cables suit the supplied M8 terminal connections, but at 80A charge current, installer-supplied cables for longer runs must be sized appropriately. As a starting point: 35mm² minimum for runs under 1 metre at 80A on a 12V system. Consult AS/NZS 3000 Table C7 and calculate voltage drop for your specific run length. Undersized cables at 80A cause voltage drop, heat, and nuisance low-voltage alarms.
- Minimum battery bank size. An 80A charger into a small battery bank causes rapid voltage overshoot and premature absorption cutoff. Minimum recommended bank: 200Ah AGM or 100Ah LiFePO4. Smaller banks will charge fast but may stress cells unnecessarily and reduce charger efficiency.
- LiFePO4 setup. This unit does not auto-detect lithium chemistry. Factory charge voltages are calibrated for lead-acid. To use LiFePO4 batteries, you must reconfigure charge parameters — absorption to approximately 14.2–14.4V, float to 13.5V or lower — using VEConfigure software via an MK3-USB to VE.Bus adapter (sold separately). Alternatively, a compatible BMS with VE.Bus BMS integration can manage charge/discharge control directly. Running factory AGM settings on LiFePO4 will result in chronic overcharge or repeated BMS protection trips.
- VE.Bus connection. For integration with a Cerbo GX or other GX device, connect via the VE.Bus RJ45 port. The unit does not have VE.Direct or built-in Bluetooth — a GX device is the correct path to VRM portal monitoring and remote configuration.
- Thermal clearance and location. Install in a dry, enclosed compartment with adequate airflow around the unit. The fan-assisted cooling requires unobstructed air movement. The enclosure is rated for protected indoor installation only — not suitable for bilge mounting, engine bays exposed to water or oil spray, or outdoor locations without an appropriate IP54-rated secondary enclosure. At 40°C ambient, plan for continuous output of 1400W, not 1600W.
- Qualified installer and compliance. All AC wiring from the inverter output must comply with AS/NZS 3000:2018. For marine installations, AS/NZS 3004.2 applies. For caravans, AS/NZS 3001. The 30A transfer switch output is a sub-board supply — downstream RCD and MCB protection is required. Earthing and bonding must be completed per the applicable standard. This work must be performed by a licensed electrician.
Compatible Accessories
- MK3-USB to VE.Bus Interface — required for VEConfigure software access, charge profile programming, and LiFePO4 setup.
- Cerbo GX — connects the MultiPlus to the Victron ecosystem via VE.Bus. Enables VRM portal monitoring, historical data logging, email and push alarms, and integration with MPPT solar chargers, battery monitors, and other Victron devices.
- Ekrano GX — alternative GX device with integrated touchscreen display.
- VE.Bus Smart Dongle — adds Bluetooth visibility to the MultiPlus without requiring a full GX device. Suitable for simpler installs where cloud monitoring is not required.
- Multi Control Panel — wall-mounted panel for adjusting the AC input current limit (PowerControl threshold) without accessing the unit directly.
- VE.Bus BMS — for installations using Victron SmartLithium batteries, the VE.Bus BMS communicates directly with the MultiPlus to manage charge and discharge cutoff.
Stock Availability Note
The CMP122200000 (MultiPlus Compact 12/2000/80-30) has been flagged by at least one Australian distributor as a product being superseded by the standard MultiPlus 12/2000/80-32 (PMP122200000). If you are specifying this unit for a build or project, contact Revolution Power to confirm current stock availability before committing. The standard MultiPlus 12/2000/80-32 is the likely long-term replacement and carries the same electrical specifications with a different physical form factor.
The Right Unit for the Right Build
Australian marine, caravan, and van buyers have specific constraints that generic off-the-shelf inverter/chargers rarely meet cleanly. The MultiPlus Compact 12/2000/80-30 addresses the combination of tight mounting depth, meaningful inverter output for real appliances, rapid recharging from shore or generator, and seamless source switching — in a single unit from a manufacturer that has been building this technology for decades and backs it with a 5-year warranty through a local dealer network.
The 30A transfer switch is the detail most buyers only notice when it is absent. The 4000W surge capacity is what separates a functioning system from one that trips every time the compressor fridge starts. The VE.Bus interface is what makes the difference between a standalone box and a system you can monitor, control, and expand as your build evolves. If those specifics match your application, this is a well-proven unit. If you have questions about suitability for your particular setup — battery chemistry, load profile, or installation constraints — contact Revolution Power before ordering.
