INSPECTION AND MAINTENANCE
The following inspections and maintenance tasks are
recommended at least once per year for best controller
performance.
1.
Confirm that the current levels of the solar array
and load do not exceed the controller ratings.
2.
Tighten all the terminals. Inspect for loose,
broken, or burnt wire connections. Be certain no
loose strands of wire are touching other terminals
3.
Verify the lights are working. This can be tested by
putting controller in mode 18 or 19 and using the
button as an on/off switch.
4.
Check that the controller is securely mounted in a
clean environment. Inspect for dirt, insects and
corrosion.
5.
Check the air flow around the controller is not
blocked.
6.
Protect from sun and rain. Confirm that water is
not collecting under the cover.
7.
Check that the controller functions and LED
indicators are correct for the system conditions at
that time.
8.
Make sure the PV array is clean and clear of
debris and snow. Confirm the array is oriented
correctly for the installation location.
