Low Voltage Battery discharge protector Disconnect Switch


For any off-grid system the batteries are the most important devices to keep working properly.
If a battery is discharged beyond a certain point it will damage the battery beyond recovery.

This device ensures the battery voltage never decreases below a preset voltage. Once it reduces below the preset voltage it will automatically disconnect the load/appliance until the voltage recovers.

There is an easy to read digital display which makes programing easy.

Please note the max load is 10 amps. For loads greater than 10 amps you can use the output of this device to power a large relay. We also have relays suitable to work with this device. Please give us a call for more details.
