4.3.3 Batteries
The panel back box can hold up to two 12V, 7Ah batteries. The batteries are not supplied with
the panel. Refer to
Specification
Section for details of recommended batteries
Note:
The panel can function satisfactorily on batteries only, if required, when mains power
is not available. However, this should only be done for short periods to avoid inadvertent
discharge of the batteries.
To Install Batteries:
1
Install the batteries in the back box. The batteries should be positioned so that their terminals
are close enough to allow connection of the short interlink cable.
2
Connect the batteries using the provided items:
a. Red battery lead (1)
b. Black battery lead (2)
c. Short battery interlink lead (3).
One end of each battery lead is fitted with a connector. The other end of the red and black battery leads
should be connected to the battery charger termination block located at the bottom, left-hand corner of
the Main PCB:
The red lead to the
+ve
connection and black lead to the
-ve
connection. Connect the other end of the
red lead (1) to the
+ve
terminal of one battery and the black lead (2) to the
-ve
terminal of the other. Connect
one end of the short interlink (3) lead to the
+ve
connector of one battery (refer to drawing on the right).
