CONTROL EQUIPMENT
30A Shunt Charge Controller
Our 30 Amp Shunt Charge Controller is a feature packed yet compact charge regulator for the Wren Micro-turbine. The unit does not require dump loads as it operates by using Pulse Width Modulation Shunt techniques to prevent the battery bank from overcharging. The unit features LED displays for both the battery state of charge and the overall system status. Further features include a automatic load disconnect and reconnect to prevent your battery bank from becoming discharged too deeply. Rather than regulating the battery charge based upon voltage readings, the unit uses a unique control system which also takes into account ambient temperature to calculate the battery banks true state of charge. This helps ensure the maximum working capacity and lifetime of your battery bank. This unit is suitable for flooded lead acid or gel type batteries.

Dump Loads & Diversion Charge Controllers
Our range of air heating resistive dump loads are suitable for use with many diversion charge controllers (which we also supply). The dump loads are available in 250watts, 500watts or 1000watts and a selection of different voltages depending on your requirements. The units are housed in a thermally resistive enclosure which high temperature ceramic terminals. The heating elements are housed behind an aesthetically pleasing air convection unit which is powder coated for maximum longevity.
