Battery
All CENTURION domestic systems are fitted with a maintenance free lead acid battery that should
provide at least three years of uninterrupted operation.
In the case of a 35A/h battery ensure that the level of liquid (electrolyte level) is correct.(NB: Due to its size
the 35A/H will be housed in a separate enclosure).
Check for corrosion of the battery terminals. Clean and apply grease as necessary.

Battery Charger
In domestic applications the R3 and R5 are battery driven. Each system has a built in battery charger
which automatically maintains the battery in a fully charged state. The casing may get hot when the
charger is in operation. This is quite normal and is no cause for concern.
The small green light (LED) on the CP75 controller marked CHARGER ON should be illuminated at all
times. This light indicates that the electricity supply from the charger unit is switched ON. NB: It does not
indicate that the charger is charging correctly and therefore it is good practice to have the charging rate of
the unit checked from time to time. This is particularly important in areas which are prone to lightning or
mains supply surges.
Specification of Charger:
No load charge voltage (measured at battery terminals with battery disconnected) 13.6 to 13.8 volts DC
Charge rate under full load - +/- 1 amp.
Solar Panel
Ensure that the panel is cleaned regularly; excess dirt, dust and leaves collecting on top of the panel will
reduce it's efficiency. Cut back any vegetation or trees that are shielding the panel from the sun.
