Your Off-Grid Experts!

Several approaches are available for power supply, power generation and power management --- depending on site specific installation requirements.

• The single utility units –- such as wastewater management only and potable water treatment only -- have no capacity to generate their own power. Conventional 110/ 240 VAC line power is used to operate these units; power can be supplied by the power grid or a third party gen-set unit.
• For off-grid applications (combined utility units) renewable energy technologies (solar, wind or water) are available.
• We suggest that in addition to the renewable energies a backup engine should be integrated to support the renewable energy systems.

Depending on the location of the system installation solar PV, wind or waterpower are integrated to work in an opportunistic manner – the power supply of the utility appliance does not entirely depend on the availability of the renewable energies ---- but the RE components are used in the most efficient way when available.

• In some application the opportunistic use of the RE components and battery bank in conjunction with a back-up gen-set, reduces the overall run time of the back-up engine to about 4 hours per 24 hour period --- but reliable 110 or 240 VAC power is available to the attached building for the entire 24 hour period.
• To allow for best fuel utilization a micro-co-generation engine / combined heat and power system (CHP) is available – generating heat and power simultaneously. These CHP systems work very efficiently in conjunction with renewable energy systems.

To further reduce the run time of the engine (back-up engine or CHP) a battery bank is used as energy storage system. At times of low power requirements the generator system completely shuts down and all power is supplied from the battery bank. An inverter / charger system controls the battery bank and in addition manages the DC power input from the RE sources (solar/wind).

• For each project the battery system, power management and power distribution system are custom designed to best suit the application environment --- applying the same modular approach to all installations.
• The battery bank and power management system can be scaled up or down as required.
