3.5 E RROR C ONDITIONS
3.5.1 Low Voltage Protection
If the battery voltage is lower than the protection voltage (Section 3.4.7), the controller will enter the low
voltage protection state and the load will be disconnected. The use of solar panels or an alternate charger is
required to charge the battery to the recovery level (Section 3.4.8). The controller will enter into the normal
working state and power will be supplied to the load once the battery voltage exceeds the Low Voltage
Protection voltage.
When in Low Voltage Protection State, the LCD will look similar to the image below.
3.5.2 Overload Protection
If the Load is drawing a current 1.2 times the rated current of the controller for three (3) seconds or more, the
controller will enter into an Overload Protection State. When in this state, any loads applied will need to be
removed one by one until power is again supplied to the loads. The controller will supply power to the loads
automatically within seconds of being within an acceptable level or you may repeatedly press the ‘DOWN’
button to recover the power supply. However, if the load is not at an acceptable level, the controller will go
back into the protection state.
When in Overload Protection State, the LCD will look similar to the image below and the Load Icon will blink
or flicker.
3.5.3 Short-Circuit Protection
If a shorted circuit is detected in the Load, the controller will enter into a short-circuit protection state. When
in this state, check the loads and/or connecting cables for any damage or short-circuiting. Once the problem
has been identified and corrected, repeatedly press the ‘DOWN’ button to recover the power supply.
When in Short-Circuit Protection State, the LCD will look similar to the image below and the Load Icon will
blink or flicker.
