2.2 Audible Buzzer

When the batteries are connected for the first time the buzzer will sound:

2 times for a 12V battery set

3 times for a 24V battery set.

The buzzer will beep when the battery voltage has reached within half a Volt of the battery
load disconnect voltage for a 12V system and within 1Volt of load disconnect for a 24V
battery set.

The Buzzer will give 4 beeps twice when the load disconnect is about to trip and 10 times
when the load disconnect has occurred.
2.3 Reset Button

Pushing the reset button cancels the buzzer.

If the unit is in Load Shed the reset button will reset the load but if the voltage is too low then
the load disconnect will operate


When the PV Voltage is higher than the battery voltage, the MPPT Regulator will assume
that it is currently day time (Dawn).

When the PV Panel voltage is lower than the battery voltage the MPPT Regulator will
assume that it is night time (Dusk).

In this mode the unit is factory set to switch on at night time and switch OFF during daytime.

A time delay may be introduced to turn on the load either immediately, 0.5 hours, 1.0 hours
or 1.5 hours after Dusk
