Multi-functional, with intelligent shore and generator power management

The Multi 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 Multi has several advanced features that provide a range of new applications as outlined below.

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. The maximum current of the transfer switch is 16 A or 30 A per Multi.

PowerControl- Dealing with limited generator, shore side or grid power

The Multi is a very powerful battery charger. It will therefore draw a lot of current from the generator or shore side supply (nearly 10 A per Multi at 230 VAC). With the Phoenix Multi Control Panel a maximum generator or shore current can be set. The Multi 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.

Four stage adaptive charger and dual bank battery charging

The main output provides a powerful charge to the battery system by means of advanced 'adaptive charge' software that fine-tunes the three stage automatic process to suit the condition of the battery, and ads a forth stage for long periods of float charging. The adaptive charge process is described in more detail on the Phoenix Charger datasheet and on download tab, above this description. In addition to this, the Multi will charge a second battery using an independent trickle charge output intended for a main engine or generator starter battery.
