10. Be very careful not to short circuit the solar array, or the controller will be damaged.
11. Make sure that water will drain from inside the case.
NOTE: Marine grade splice (supplied by user) may be substituted for the blue wire nuts included.
4-8 Connecting Multiple Batteries
This section is added as a courtesy for advanced users. It is highly recommended that your Multiple Battery
systems are all unique and require expert design assistance.
Multiple Batteries Installations:
2 x 12V batteries
in parallel
2 x 6V batteries
in series
Connecting Batteries - Series:
When batteries are connected in series the voltage is cumulative while the
same capacity rating (amp hours) is maintained.
Connecting Batteries - Parallel:
When batteries are in parallel the capacity (amp hours) of the battery is
cumulative while the voltage of the individual batteries is maintained. Batteries should be same rating and
same type of battery, i.e. flooded, gel or AGM.
4-9 Connecting Multiple GSP Solar Panels in Parallel
This section is added as a courtesy for advanced users. It is highly recommended that your Multiple Solar
Panel systems are all unique and require expert design assistance.
Note: By adding the voltage ratings of all the solar panels together will determine if you need to connect the
panels in series or parallel configuration.
Connecting GSP Solar Panels - Parallel:
When connected in parallel the charging current (amps) of the
panels are cumulative while the voltages of the panels remain the same (if there is no shading). For example,
two 12-volt, 3-amp panels wired in series would create a 12-volt, 6-amp system.
Solar Panels should be same rating and same type.
When using a single controller to regulate multiple panels be sure to select the suitable charge
controller to cover the total short circuit amps generated by all the panels added together.
It is recommended (and a better design) to use a dedicated GANZ 4.5A charge controller (GCC-4.5A
Kit) to each solar panel in a multiple parallel configuration. This allows each solar panel to charge
independently and not have any effect on the other panels, even if one or more panels are shaded.
To wire two devices in parallel, you connect the positive terminal of one to the positive terminal of
another, as well as the negative terminal of one to the negative terminal of another. In parallel wiring
voltage is constant while current is additive.
