CAUTION: A fuse which current is 1.25 to 2 times the rated
current of the controller, must be installed on the battery side
with a distance from the battery not greater than 150 mm.
CAUTION:
If the controller is to be used in an area with
frequent lightning strikes or unattended area, it must install an
external surge arrester.
CAUTION: If an inverter is to be connected to the system,
connect the inverter directly to the battery, not to the load side
of the controller
.
Step 3: Grounding
XTRA series is a common-negative controller, where all the
negative terminals of PV array, battery and load can be
grounded simultaneously or any one of them will be
grounded. 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.
