Victron Pheonix Mutli Plus 12V - 3000VA - 120a (16a relay)

Victron Phoenix Multi Plus

Multi-functional
The Multi Plus 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. Models range from 800VA to 5000VA per module. True Sine Wave means that this unit will any type of appliance (such as televisions, washing machines, microwaves, fluorescent lighting, hair straighteners) which may have problems when using other types of inverter
.
Victrons Unique PowerAssist feature
The MultiPlus will prevent overload of a limited AC source. The Multiplus monitors the AC input current (for example from shorepower) and will automatically reduce battery charging when otherwise an overload would occur. If the AC requirement surpases the AC in, the Multiplus will sychronise both inverter output and AC in to boost the power available with power taken from the battery bank.

Uninterrupted AC power (UPS function)
In the event of a grid failure or shore or generator power being 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.

Virtually unlimited power thanks to parallel operation
Up to 6 Multi's can operate in parallel to achieve higher power output. Three phase or split phase operation is also possible. Please datasheets to see which models have paralleling, three-phase and split phase capabilities.
