Possible issues:
 The battery is too small to support the system after the sun is not charging it.
 The accessories being used have a high draw and are draining the battery.
 The solar panel is facing the wrong direction or has shadows.
 The solar panel is too small to charge the battery past what is being used.
 The battery is aging and cannot recharge.
Fixes for repeated low battery:
 If the battery is over 3 years old replace the battery.
 The first thing to do is to test the battery voltage at the end of the day when the sun is set-
ting. If the battery is not fully charged (13.4VDC) then the solar panel may be too small or
positioned wrong.
 If the battery becomes fully charged at the end of the day but then drains overnight the
solar panel is re-charging enough but the accessories are either drawing too much or the
battery is too small for the system. Purchase a larger battery or find a different power source
for the accessories.
 The solar panel should be facing south. Any other direction and it is not getting direct sun-
light because we are in the Northern hemisphere.
 If any part of the day cast shadows move the solar panel or cut away branches. Ambient
light will not charge the system; this is the same for the panel facing the wrong direction.
Although it looks like light is reaching the panel it has to be direct sun light.
The battery continually reaches LU and is a plug installation
It is either the battery is charger malfunctioning or the battery is aging.
Fixes for repeated low battery with plug in option:
 If the battery is over 3 years old replace the battery.
 Test the output of the charge board, there should be 18VDC being fed to the battery. If
there is not voltage to the battery terminals test the transformer for output. Replace either
the transformer or the charge board, which ever part is not putting out power.
 Bring the battery to an auto parts store for a load test, if the battery reads ok at rest but fails
under load, the battery has a dead cell and needs to be replaced.
The display does not show AU in the open position with dip switch 1 on (up)
