Watertight EnerMatic Controller
What is a diesel battery charger, (DBC)? It's a small diesel engine driving a high output alternator to minimze engine horsepower and fuel consumption when compared to an AC generator with a subsequent electronic battery charger. It is also smaller and weighs less than the AC generator and electronic battery charger. Modern inverters provide AC power of a higher quality than public utilities. An AC generator almost never produces the right frequency or voltage and most often is wasting fuel running at light loads.
Seven Standard Models
There are seven standard models to choose from, covering a range of voltages and power.
The standard models are shown in the table below. The kilo-Watt rating is calculated using rated Amps and the absorption setpoint voltage.
Every DBC comes with the watertight EnerMatic Controller. Included are the alternator and battery shunts and the battery temperature sensor. Additional relays or modules may be required to control solar panels and/or wind/hydro generators.
The watertight EnerMatic Controller uses connectors rated to IP-67 so it is ready to go into an ocean buoy, or a mountain top communications shack.
All of the DBCs will run on petroleum diesel or good quality biodiesel. Fuel pre-heat may be required.
The diesel battery charger can be cooled by several means:

Dimensions and Weights
The table below show dimensions in inches(centimeters) and pounds(kilograms).
Web Server Option
EnerMatic Web Server
The EnerMatic Controller has two serial ports. Both serial ports provides complete access to all data and functions of the unit.
One serial port provides a terminal interface to be used with any PC or laptop computer.
The other serial port communicates via a Remote Access Protocol that allows another computer to interact with the EnerMatic. The RAP protocol is published so that anyone can write a program to communicate with the EnerMatic.
Ample Power provides a small, very low power web server, called Rap-Web which communicates with the EnerMatic and formats information into web pages that represent data and control panels. A user can aggregate data and control functions into panels of their own choosing.
Rap-Web has an ethernet port, USB ports, and additional serial ports. It can be connected to an intranet, and routed to the world via a firewall/router.
The user can also select data items to be logged and plotted periodically for web presentation. This allows tracking parameters over time, such as battery voltage, engine RPM, or alternator Amps.
Intake Silencer Option
There's a lot more to noise reduction than just enclosing an engine. An enclosure that allows the engine to pull hot intake air will lead to premature engine failure. The engine must get ambient intake from outside the enclosure(s).
Without an intake silencer, noise levels will be dramatically higher. In many remote applications, that may not be a problem.
We have tested many solutions before settling on the intake silencer offered as an option.
Hot Water Option
While the DBCs are efficient, there is waste heat which can be used to make hot water, or heat living spaces. Distributing this heat is done with a circulating pump which is turned on and off by the EnerMatic Controller. The controller senses engine coolant temperature and turns on the pump when the engine is warm enough.
The DBC hot water system can be connected to the same coolant circuits as the passive solar panels, however great care must be taken to keep the liquid circuits full at all time.
Heating a water tank can be quickly accomplished by using an inverter to drive the AC heating element, and the DBC to circulate coolant through the coils in the tank. The inverter represents a significant load for the DBC, so not only does it provide heat via the AC element, but it also causes the engine to heat and thus provide more energy for the hot water tank.
The Hot Water Option requires the EnerMatic Controller and includes the DC circulating pump;
Remote Cooling Options
Standard units are built using the factory radiator mounted to the engine. To be effective, the radiator needs to be mounted against an exterior wall such that ambient air is pulled through the radiator. The air pulled must also be exited from the compart to avoid overheating. Adequate ventilation for the engine generally means that noise levels are noticeable.
A remote radiator or marine heat exchanger can be used to reduce air circulation requirements, and subsequently reduce noise levels. The air intake to the engine should always be drawn from ambient temperature ...never from inside a hot enclosure.
A custom aluminum remote radiator is available. An electric fan is included. Fans are more efficient pulling air than pushing air. Either fan can be ordered. The EnerMatic Controller can be programmed to run prior to starting the engine and for a specified time after the engine is stopped.
A marine heat exchanger can be used, where engine coolant is circulated on one side and raw water is circulated on the other side. A marinized unit requires the heat exchanger, a raw water pump, and a custom header to cool the exhaust.
Marine Installation Kit Option
The Marine Installation Kit includes parts necessary to plumb raw water to the heat exchanger.
Fuel System Kit
All engines need well filtered fuel.
Most engines have an mechanical diaphram pump, which has a limited lift range. Even so, an electric fuel pump is useful to pre-charge/bleed the fuel system.
The EnerMatic Controller can operate the fuel pump continuously, or in a pre-charge mode where it operates before cranking the engine and for a programmed time after the engine starts.
The fuel system kit includes a Racor housing and cartridge and a fuel pump.
