The DCGO-14 is a 14 kW variable-speed DC generator set built around a Kohler turbocharged diesel and an Innotec Power 310 series permanent magnet alternator. It is available on a 24 V or 48 V nominal bus, and feeds a battery bank or a DC load directly — there is no inverter stage and no fixed engine speed.

Full specification, charging behaviour and the rest of the range at each bus voltage are on the 24 V DC generator and 48 V DC generator pages. The engine, alternator, controller and frame below are common to both builds.
Permanent magnet alternator
Innotec Power 310 series flywheel-mounted PMA, rated 14 kW DC with a maximum speed of 3,000 rpm and a working range of 2,200–3,000 rpm. Brushless and bearing-less construction, Class H insulation, forced cooling with an internal fan, and a high variable frequency output with low ripple.
The same alternator family is used across the DC genset range. If you need the alternator on its own rather than a complete set, see the DC generator head.

Control panel and protection
Every DCGO genset ships with a variable-speed DC genset controller running a precision PID loop, which matches the charging characteristic rather than simply holding a fixed voltage. Protection covers overvoltage, overcurrent, overspeed, overheat, thermal and short circuit.
- ECU connection through J1939 CAN (option)
- Isolated volt–amp measurement
- 100 event logs with time stamp and measurements
- Field-adjustable parameters
- MODBUS communications
- GSM SMS message on fault
Fuel tank options
Three fuel configurations are available: open-frame with no tank, an integrated tank of 200, 400 or 600 litres, or a custom capacity to suit the installation.
Why a DC genset rather than an AC set plus rectifier
A DC genset lowers operating cost by removing the conversion stage. A passive rectifier feeds the DC bus directly and engine speed is varied to regulate voltage, so the machine is not tied to a fixed 1,500 or 1,800 rpm just to hold frequency. Peak efficiency is engineered above 93%, and the alternator is brushless and bearing-less — no slip rings, no exciter, no diodes to fail.
Where the 14 kW is used
- Auxiliary power units on trucks and specialist vehicles
- Hybrid and autonomous vehicles and equipment
- Telecom sites and data centres
- Mobile light towers and material handling
- Battery charging on off-grid and standby installations
Other DC generator sets
Step down to the 5 kW DC generator on an air-cooled single-cylinder Kohler, or up to the 25 kW DC generator on the larger KDI1903TC. The DC generator range covers 24 V to 96 V across generator heads, PTO-driven units and complete sets.
