3.
With the solar array still covered, switch ON the refrigerator. THE
REFRIGERATOR COMPRESSOR SHOULD NOW RUN.
4.
If the COMPRESSOR DOES NOT RUN PROCEED TO THE NEXT STEP ON
THE FAULT FINDING CHART.
5.
If the COMPRESSOR DOES NOT RUN:
(a)
Check the level of distilled water in each cell of each battery, and top up
the
water if necessary (see page 57)
(b)
Recharge each battery (unless battery manufacturer or supplier states this
is not to be done for your batteries)
6.
Recharge the batteries by switching OFF the refrigerator and:
(a)
Allowing five days for the batteries to be recharged by the solar array, OR
(b)
By removing the batteries from the refrigerator and charging with a battery
charger.
(c)
When fully charged by either method, disconnect each battery and leave
each battery for 2 hours.
(d)
Connect the battery (2 batteries for 24 volts system) to the refrigerator,
switch in the refrigerator and measure the voltage between the + and –
terminals of the compressor controller.
(e)
If the voltage of the battery with the compressor running is LESS THAN
12.5 volts (or 25 volts for 24 volt system), the battery is not holding the
charge and should be replaced (see page 87)
(f)
Repeat step (d) for each of the batteries you have charged.
(g)
Reconnect the correct number of batteries required for the solar
refrigerator.
(h)
If NO batteries need replacing, PROCEED TO THE NEXT step on the
FAULT FINDING CHART, which corresponds with the symptom you, have
diagnosed. This will enable you to find out if the low state of charge of your
batteries is the result of other fault in your system.
