Out of Stock

Easily protects your renewable energy battery bank from overcharging. Must be used with a Magnum MS Series inverter.


Magnum AC Load Diverter - 4000W (ACLD-40)

The Magnum ACLD-40 Load Diverter monitors the voltage of your renewable energy system's backup battery bank and diverts excess energy to an AC load if the battery voltage rises to a predetermined level to prevent the batteries from overcharging. It will continue to engage and disengage the diversion load as often as necessary.

The ACLD-40 works with solar, wind, and hydroelectric renewable energy systems using a Magnum MS Series inverter. It is compatible with 12VDC, 24VDC, or 48VDC systems, yet allows the use of common, resistive AC household loads for load diversion instead of the hard-to-find DC loads supported by other charge controllers.

If wall-mounting the ACLD-40 vertically, the MPX-CB Conduit Box (available separately above) is required to meet code compliance.
