So what does an inverter do? Simply put, it converters DC power to AC power. Solar panels produce DC and batteries store DC, however our appliances run on AC, as does the power grid. That is why all solar systems and battery storage systems need an inverter.
The required size of the inverter/charger depends on the type of installation.
In a grid-parallel installation, the size of the inverter/charger can be (much?) smaller than the highest expected nominal and peak loads. For example, to cover the base load of a two-person household, an 800VA inverter/charger may be sufficient. For a family, a 3000VA inverter/charger can run most appliances – as long as not more than one of them is running at the same time. This means that the system can reduce grid power consumption from late spring to early autumn – perhaps to zero – with sufficient storage.
High surge power rating – The surge power rating of the Victron inverters is very good being roughly 2.5 times the rated continuous power output. This equates to a 2400W (2.4kW) continuous output inverter providing peak output of 6000W. This is enough for the short start-up spikes from pumps, compressors, etc.

MultiPlus Compact-functional The MultiPlus Compact gets its name from the multiple functions it can perform. It is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology and a high-speed AC transfer switch in a single compact enclosure. Beside these primary functions, however, the MultiPlus Compact has several advanced features that provide a range of new applications as outlined below. Uninterrupted AC power In the event of a grid failure, or shore or generator power being disconnected, the inverter within the MultiPlus Compact is automatically activated and takes over 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. PowerControl – Dealing with limited generator or shore side power With a Multi Control Panel a maximum generator or shore current can be set.
The MultiPlus Compact will then take account of other AC loads and use whatever is extra for charging, thus preventing the generator or shore supply from being overloaded. PowerAssist – Boosting the capacity of shore or generator power This feature takes the principle of PowerControl to a further dimension allowing the MultiPlus Compact to supplement the capacity of the alternative source. Where peak power is so often required only for a limited period, it is possible to reduce the size of generator needed or conversely enable more to be achieved from the typically limited shore connection. When the load reduces, the spare power is used to recharge the battery. Programmable relay The MultiPlus is equipped with a programmable relay that by default is set as an alarm relay. The relay can be programmed for all kinds of other applications however, for example as a starter relay for a generator
Multifunctional
The MultiPlus, as the name suggests, is a combined inverter and charger in one elegant package. Its many features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology, plus multiple system integration features.
Models: 800VA, 1200VA, 1600VA, 2000VA, 3000VA, 5000VA
Adaptive 4-stage charge characteristic: bulk – absorption – float – storage
The MultiPlus Compact features a microprocessor controlled ‘adaptive’ battery management system that can be preset to suit different typs of batteries. The ‘adaptive’ feature will automatically optimize the process relative to the way the battery is being used. The right amount of charge: variable absorption time When only shallow discharges occur (a yacht connected to shore power for example) the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged.
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 or shore side supply with power taken from the battery.
In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and 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.
