5. Connect the battery Positive (+) to the Power Pak’s DC terminal Positive (+) and battery Negative (-) to
the Power Pak’s DC terminal Negative (-). Connect the battery bank to the Power Pak with AWG 2/0
cables.
6. Connect the batteries together to match the input of the Power Pak. MINI – 12V, COMPACT – 24V,
GRANDE – 48V
6.5 Solar Panels Connection (optional)
This section describes how to connect a solar panel array to the Power Pak. This is optional. If solar panels are
not connected, then another power source is required, e.g. electrical utility, diesel generator, etc.
WARNING
Before connecting the solar panels, ensure the solar panel array is configured to provide the correct
voltage for the specific Power Pak model being installed. See Appendix 1 for specifications. Exceeding the
voltage limit can damage the Power Pak.
STEPS to connect solar panels:
1. Make sure the MPPT-Battery and the MPPT-PV breakers on the Power Pak are off.
2. Before connecting the solar cables to the Power Pak, measure the voltage to ensure the polarities are
correct.
3. Connect the solar panel Positive (+) to the PV Positive (+) on the Power Pak and the solar panel
Negative to the PV Negative (-) on the Power Pak.
4. After the battery and solar panels are connected, turn on the battery switch, then the MPPT-battery
breaker. WAIT for 2 seconds, and then turn on the MPPT-PV breaker. The Charge Controller Display
will turn on and show the solar energy information.
6.6 Expanding the System: Additional Charge Controllers &
Wind Turbines (Optional)
Some users may wish to provide additional power sources that exceed the Power Pak’s built-in capabilities
(see table below). For example, a very large solar array, a wind turbine, or a micro-hydro turbine.
