General description
The OctoPower 4 + AC (12VDC) is a battery-based power system for the provision of 3 kW 230 V 50 Hz from a 12 V lead-acid or lithium battery. The system includes a silent running diesel Generator of 4.4 kVA/ 3.5 kW power, our Piccolo 5 (USA specification Piccolo 4). In case the application is mobile/ land based we offer the Scalino 4 as the best generator option.
The Supreme Combi 12/3000-100A is the heart of the system and is connecting to AC land/ shore power (230 VAC, 50 Hz), the Piccolo 5 generator, the on-board 230 V 50 Hz appliances and the 12 VDC battery. Devices to connect the battery or batteries to solar panels and the alternator (s) of inboard/ outboard engines can be included as well.
