5.1.5 Generator replacement system

The optional generator replacement system gives you extended use of 110 V or 230 V power to run the electrical appliances and equipment on your boat when you have no access to shore power.

The generator replacement system is located in the aft technical compartment. The system consists of a high-capacity 500 Ah battery pack (can be expanded to 1000 Ah) and a charger / inverter unit. Depending on your choice of equipment, the optional shore power can be used to charge the battery pack of the system.

You can monitor the charge level of the battery pack and the status of the generator replacement system with an application on the multifunction display on the helm station.

It is important to monitor the charge level, since the bilge pumps run on the battery pack power. If the charge level of the battery pack of the generator replacement system runs too low, or if there is a fault in the system, the system shuts itself down automatically. When shutting down, the safety relay switch of the battery pack switches automatically to the OFF position and the bilge pumps shut down, too.

When the boat is not used for an extended period of time, put the safety relay switch to the OFF position.
