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.\u003c\/p\u003e\n    \u003cp\u003eThe 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.\u003c\/p\u003e\n    \u003cp\u003eThe \"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.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003chr\u003e\n\n  \u003ch2\u003eKey Features\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003e2000VA \/ 1600W pure sine wave output at 25°C — 1400W continuous at 40°C.\u003c\/strong\u003e Plan your load calculations around the 1400W figure for enclosed Australian installations in summer conditions.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003e4000W peak (surge) output.\u003c\/strong\u003e Handles motor start loads, induction cooktops, and short-duration high-demand appliances that would stall lesser units.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003e80A adaptive 4-stage battery charger.\u003c\/strong\u003e Runs bulk, absorption, float, and storage stages.

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.\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003ePowerAssist\u003c\/strong\u003e 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.\u003c\/p\u003e\n  \u003cp\u003eThis 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.\u003c\/p\u003e\n\n  \u003chr\u003e\n\n  \u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBattery cables.\u003c\/strong\u003e 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.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMinimum battery bank size.\u003c\/strong\u003e An 80A charger into a small battery bank causes rapid voltage overshoot and premature absorption cutoff.

Smaller banks will charge fast but may stress cells unnecessarily and reduce charger efficiency.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLiFePO4 setup.\u003c\/strong\u003e 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.

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.\u003c\/p\u003e\n\n  \u003chr\u003e\n\n  \u003ch2\u003eThe Right Unit for the Right Build\u003c\/h2\u003e\n  \u003cp\u003eAustralian 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.\u003c\/p\u003e\n  \u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003c\/div\u003e\n","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":44876200771638,"sku":"CMP122200000","price":1631.22,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/2989\/7782\/files\/MultiPlus-Compact-12-2000-80-30_front_300dpi.webp?v=1772069344","url":"https:\/\/revolution-power-australia.myshopify.com\/products\/victron-multiplus-compact-12-2000-80-30-230v-ve-bus","provider":"Revolution Power Australia","version":"1.0","type":"link"}
