Dump Loads For use with our Tristar TS-45/60, Xantrex C40/C60 charge controllers, these dump loads are effectively high power air heating elements. The charge controllers are used in 'Load Diversion' mode, and as such, they begin to dissipate any unwanted power into these dump loads as your battery bank becomes fully charged. The charge controllers use a Pulse Width Modulation Output governed by a built in battery charging programme, which means that they gradually switch the power to the dump load (this is a requirement of most wind turbines - to be kept under load) as the voltage increases, thereby keeping your batteries in tip top condition. It is vital to use a charge controller to prevent damage to your batteries, especially if you leave your system unattended for long periods of time, and without loading your batteries with an inverter, or other suitable device. These dump loads
should be mounted as close as possible to your charge controller.
They should be mounted in free circulating air, and not in an enclosed
space. All
cabling used should be securely connected.
Please ensure that you choose the correct voltage of dump load for the
battery bank voltage you are charging. The dump loads are rated at
600W for the 12V and 1kW for the 24 and 48V systems to complement the
Futurenergy Turbines and PMGs or any similar output devices. |

Immersion Heater 1000w @ 48 volt immersion heater, if using
at a lower voltage i.e.. 24V You will of course only get approx a quarter of the
Wattage. This can
be used in a water heating application in preference to dumping any excess
energy from the battery into the air with a standard dumpload. The heating
element is 12” long and also has a 7” copper pocket. This pocket is designed
to take normal thermostats, however in a dump load configuration you should
not turn off the heater element unless you have an alternative load that
comes in to maintain the load on the system. It connects to the tank via a
standard UK 2.25” BSP thread,
as a direct replacement for the normal Mains Immersion Heater. |
