Battery voltage is low.
Maintenance
Maintaining Solar Panel
To ensure optimum performance, Furrion recommends the following maintenance measures:
● Clean the glass surface of the solar panel when required. Always use clean water and a soft
sponge or cloth for cleaning. A mild, non-abrasive cleaning agent may be used to remove
stubborn dirt. Do not use cold water to clean panel if the surface is extremity hot as rapid
temperature change could lead to cracking.
● Clean solar panel more frequently during drier months, as they may become covered in dust
more quickly. A pressure washer is not recommended.
● Check the electrical, grounding, and mechanical connections every six months to verify that
they are clean, secure, undamaged, and free of corrosion.
● Remove snow, ice, or other debris when build up occurs.
● Caution: Observe the maintenance instructions for all components used in the system, such
as support frames, PV connectors, charge controller, batteries, etc.
Maintaining Multiple Batteries
To properly maintain multiple batteries they should be the same type (gel, flooded or AGM) and
condition. Always connect batteries in parallel (negative to negative and positive to positive)
to maintain a 12V system. Never connect batteries at different states of charge or voltage.
The charged battery will rapidly transfer energy to the discharged battery possibly causing
catastrophic failure.
Long Term RV Storage
If your RV will be stored in extremely cold climates you may need to remove your batteries to
prevent them from freezing. Please note if your solar panel(s) are covered by snow they will
not produce power and can not be depended upon to keep the batteries charged. For battery
storage in mild climates solar system will provide more power provided sufficient sunlight and
limited load. Make sure that all passive/phantom loads are removed from the batteries, i.e. DVD
players, clock radio, etc. to make sure the solar panel(s) can keep the batteries charged even
with reduced sun exposure.
The battery is over-discharged and will recover when
recharged adequately.
Reposition vehicle if possible to provide more direct
sunlight. If PWM Battery Maintainer can not sustain
adequate charge to the battery, connect the coach to shore
power or generator. Reducing electrical loads in the coach
will also help maintain adequate charge of the battery.
