General description
A 3kW Battery-based power system for the provision of AC power (DC power is optional), designed for boats, vehicles and houses. Consists of one power electronics module and one or two Lithium Ion battery packs. All components will have been pre-installed/mounted in our factory.
The OctoPower 3 is supplied as an easy plug and play installation, with connections to: AC power (land/shore) input, solar panel(s) input, connection to outboards or inboard starter battery or vehicle starter battery. The maximum charge power from this source is 1 kW (100 Amps / 12 V or 50 Amps / 24 VDC). There are outlets for 230 VAC and (optional) 12 VDC. A 120 VAC 60 Hz output is also available.
