5 Technical description
The device is a smart split charge relay with four functions:
1.
Parallel creator between the house battery and starting battery (only if the vehicle engine or a charging source is
running)
2. Starting battery guard
3. House battery guard
4. Manual electronical battery disconnector
Aer a few seconds with the engine or a charging source running, the device switches on the internal relay to
connect the the two batteries in parallel, that will charge them both at the same time. During this stage the LED
indicator is on.
If the device detects a voltage lower than 10.5 V during house battery use, the device will immediately disconnect
the battery from the loads. If this happens, the LED indicator turns off. The device reconnects the battery to the loads
when a charging source is connected, such as an alternator, a battery charger, or a solar panel regulator.
The button on the device is used to manually disconnect the house battery from loads and from the starting battery.
The house battery will be reconnected to the loads when the battery voltage has risen to 12.3 V. The house battery
and the starting battery will be in parallel when the starting battery voltage is 13.3 V.
