Use a multimeter to test if the photovoltaic string is connected in reverse
Employ a multimeter to measure voltage, ensuring that the probe's red end connects to the positive terminal and the black probe touches the negative terminal. A positive reading confirms correct polarity orientation. First, you must turn off the power going into your DC circuit breaker box. However, if one lead of a terminal in the DC circuit breaker box is connected while. The voltage difference allows electric currents to flow from one end of the wire to the other. Set your multimeter to measure DC current (usually indicated by a symbol resembling an “A”). Select a current range suitable for your panel (typically above the expected Isc).
