EnerMatic Controller

Introduction to Energy Automation

The EnerMatic Controller integrates and automates all monitoring, regulation and control of small energy systems. The parameters of the main energy bank are continuously monitored, and the acquired data is used to control solar, wind, and engine driven chargers. The auxiliary engine is started when necessary, and shut off when the batteries no longer need it. The EnerMatic Controller is compatible with Ample Power bio-diesel battery chargers, rated up to 300 Amps, and may be used with AC generators driving inverter/chargers.

All control actions are automated according to user programmed parameters. Programming the EnerMatic is easily done using any personal computer, VT100 terminal or other device that can emulate a VT100. The user interface is based on menus, forms, and selections ...the kind of interfaces used on the Internet.

The EnerMatic is rich in features, highly accurate, and operated by firmware which can be upgraded any time a new version is released ... without removing the unit from the system. Simply download the latest version from the Internet and install it!

The EnerMatic has been designed to take the place of a myriad of other controllers, regulators, and monitors. If you presently have an energy system, or plan to own one in the future, the choice has never been simpler ...EnerMatic.

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.

Rap-Web software uses javascript to build web pages and has been tested with popular browsers for compatibility.
