Step 4：Grounding
Tracer AN series is a common-negative controller, if any of one negative is grounded, all the negative
terminals of PV, Battery will be grounded simultaneously. However, according to the practical
application, all the negative terminals of PV array, battery and load can also be ungrounded, but the
grounding terminal on its shell must be grounded, which may effectively shield the electromagnetic
interference from the outside, and prevent some electric shock to human body due to the
electrification of the shell.
CAUTION: For common-negative system, such as motorhome, it is recommended to use a
common-negative controller; but if in the common-negative system, some common-positive
equipment are used, and the positive electrode is grounded, the controller may be damaged.
