LVD - Low Voltage Disconnect
Return to modifications

LVD currently used for the fridge power only - protects batteries from over discharge
The reason I fitted a LVD is that the fridge draws around 5 amps when running, it would be possible to take too much power from the batteries causing damage (if dropped below 12 VDC )
This could happen over night and I want to avoid deep discharging the batteries.

The LDV will disconnect the power to the fridge before the batteries get too low.

The unit I use was a programmable one from Ebay, the low voltage can be set as well as the cut back in voltage.
