Battery-based 3 kW power system for the marine market
Designed for boats. Consists of one power electronics module and one or two Lithium 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. 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.

“Perfect power solution to operate A/C and other comfort appliances”
I am convinced that the OctoPower 3 is a perfect alternative to a diesel generator for this type of boat. I also told this to my suppliers, including Axopar. The WhisperPower system is quiet, powerful, retains power for a long time and quickly recharges via the outboard alternators.”
Patric Polch | owner of Boote Polch
The OctoPower 3 system is on the option list at Brabus and Axopar.
