3.7.6 SOLAR PANEL(S) — YELLOW CABLE
The
YELLOW
wire connects solar input to the BCDC. If solar is not installed, tape over
the end of the wire.
IMPORTANT:
DO NOT connect solar panels that have inbuilt regulators. The BCDC Core has
an inbuilt regulator that may not function correctly if regulated solar panels are connected.
NOTE:
Most residential solar panels are not suitable for use with BCDC as they have an open circut
voltage that exceeds the 32 V limit of the BCDC Core input.
CONNECTING MULTIPLE SOLAR PANELS
There is no limitation on how many solar panels you can connect in parallel to your BCDC,
but you will need to size the cables correctly.
When connecting multiple 12 V solar panels, it is important to connect them in parallel.
Connecting in parallel ensures the output voltage remains the same while increasing the
overall power output of the array.
Figure 3.7.6.1:
Connecting solar panels in parallel
Example only, panels/configurations may vary.
The BCDC Core can be connected to a solar panel array with a larger wattage than the BCDC's
maximum Output Power rating (refer to
"Table 3.7.1: Maximum Output Power rating" (page 25)
).
The Battery Charger will automatically limit power going to the unit if the panels supply more than
the maximum wattage needed.
