Meet the W-GV 2
The W-GV 2 combines the latest diesel engine technology with a new way of producing electrical power. Instead of adding an alternator with fixed speed on the back of the fly-wheel, we have designed a very compact permanent magnet alternator (PM), located just behind the engine. The W-GV 2 is designed to produce DC power by connecting up to 3 superchargers (DC PowerCubes), which can be connected to shore/land power as well.

Unique Genverter Technology
For cases when a constant AC high power consumption isn’t required, installing a Genverter© system with one or multiple DC PowerCubes, combined with an AC PowerCube inverter, can prove to be a smart decision.
The advantage of this unique system is that a non-stop AC power is always available, even without a running engine. This is thanks to the 4, 7 or 14 kVA AC PowerCube inverter which is connected to one or multiple onboard lithium batteries being charged by one or several DC PowerCubes.
How it works
Whenever the 24/48 VDC batteries need to be recharged, the Genverter© starts up automatically. At the same time, the DC PowerCube is connected to the shore power – during shore power connection, the various onboard batteries are charged with a maximum of 3.5 kW or a multiply of this.
Using the remote control panel, supplied as standard, the shore power can be set to the required ampere value (4,6,8,10,16 A). The DC PowerCube also features a separate charging output for 12 or 24 VDC.
Stage V / EPA / Tier 4, low emission, radiator / liquid cooled engine
Only the best 2 & 3 cylinder engines are applied: long lasting, reliable, silent engines, complying with EPA /Tier 4 (USA standard) and Stage V (European standard). The engine and PM alternator back-end are connected into one cooling circuit and kept on a constant temperature via a heat exchanger (indirect cooling applied).
