Always verify each solar panel’s polarity with a
volt meter before making any connections.
The solar panels are to be wired together in series.
Be sure to verify the solar panel specification of
open circuit voltage measurement (approx. 20VDC).
When properly wired together in series, the voltage
measurement on the wires feeding the Solar
Regulator will measure approx. 40VDC in open circuit.
Wire entrance hardware per local codes,
water tight as required (3 places).
