Inverters and Inverter/Chargers |
Inverters - The purpose of an inverter is to supply power to AC appliances (such as a coffee maker or microwave) by inverting DC battery power to AC power. An inverter draws power from the battery bank and supplies it to AC appliances. Inverters are available in various sizes measured in watts of output. The most common inverter capacities range from 1,500 watts to 3,000 watts. Most inverters are about 80-90% efficient which means 80-90% of the power drawn from the battery bank is converted to AC power. There are two types of inverters; pure sine wave and modified sine wave. Pure sine wave inverters output current in the form of a sine wave similar to power from the grid. Modified sine wave inverters output current in a square pattern of alternating current. Appliances, especially electronics, run better with a pure sine wave. Modified sine wave inverters are considerably less expensive than pure sine wave inverters.
Inverter/Chargers - The purpose of an inverter/charger is to both supply power to AC appliances from the battery bank and to charge the battery bank from grid power or a generator. In summary, invert DC to AC current for powering appliances and invert AC to DC current for charging the battery bank. Most inverter/chargers are equipped with an automatic transfer switch (ATS). When grid or generator power is applied to the inverter/charger, the ATS bypasses the inverter and passes the AC current through to the AC appliances and also connects to the built in battery charger to charge the battery bank. When grid or generator power is turned off or removed from the inverter/charger, the ATS automatically disconnects the battery charger and connects the inverter so the AC appliances are powered by the battery bank.
Victron Energy offers a full line of inverters and inverter/chargers.

Quattro Inverter/Charger - Similar to the MultiPlus, the Quattro is also a combined inverter and charger. Additionally it can accept two AC inputs and automatically connect to the active source (i.e. automatically switch between shore power and a generator). Its many features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology plus multiple system integration features such as three or split phase operation and parallel operation.
Two AC inputs and two AC outputs - The Quattro can be connected to two independent AC sources, for example shore-side power and a generator, or two generators. The Quattro will automatically connect to the active source. The main output has no-break functionality (it will output power from any source, batteries or AC inputs). In the event of a grid failure, or shore or generator power being disconnected, the Quattro takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption. The second output is live only when AC is available on one of the inputs of the Quattro. Loads that should not discharge the battery, such as air-conditioning or a water heater can be connected to this output.
Unique Power Assist feature - The MultiPlus will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator of shore side supply with power taken from the battery.
Remote Monitoring and Control - When coupled with a GX device (e.g. Cerbo GX) you can monitor and control your Multi and system or systems' locally (LAN) or remotely via the internet from anywhere in the world.
