Victron MultiPlus Compact 24/2000/50-50 120V [CMP242200100]

Victron MultiPlus Compact 24/2000/50-50: 2,000VA = 1,600 watts continuous

A 24V inverter/charger from Victron Energy with 120V AC output: an inverter, a battery charger (up to 50 A) and an automatic transfer switch (50 A) in one box. On shore power or a generator it charges your batteries and passes AC through to the boat; when shore power drops, it switches to the batteries.

Why the VA number isn't the watts: Victron rates its inverters in VA (volt-amps). This one delivers 1,600W continuous at 77°F (25°C) and 4,000W peak for motor and compressor start-up. Size your loads around 1,600W, not 2,000W. Compare all Victron inverters →

What it will run on a boat

At 1,600W it handles a full-size microwave, coffee maker, power tools or a hair dryer, one big load at a time, with electronics running alongside. Add up everything you'll run at the same time and leave 20–25% headroom.

Battery draw and wiring

At full continuous output it pulls roughly 71 amps from a 24V battery bank (1,600W ÷ 24V ÷ 94% efficiency). Size the battery cables, DC fuse and battery bank for that current. The manual lists Victron's recommended cable and fuse sizes for this model.

Mounting it in a hot engine room?

Continuous output drops as the temperature rises: 1,450W at 104°F (40°C), 1,100W at 149°F (65°C). In the Keys an engine room or lazarette can easily run hotter than 104°F, so size for the hottest spot you'll mount it and give it airflow.

Idle draw at anchor

Switched on with nothing plugged in, it uses about 11W, roughly 11Ah per day from a 24V bank. AES mode cuts that to 8 W (search mode: 4 W) when you don't need full power.

On shore power

Set the AC input current limit to match your dock pedestal or generator. With PowerAssist, it cuts back battery charging and adds battery power during peaks so you don't trip the shore breaker. Charging is adaptive, 4-stage (default 28.8 VDC absorption / 27.6 VDC float), programmable for lithium, AGM or flooded banks. A separate starter-battery output (4 A) keeps the engine battery topped up.
