● Do not connect loads between the SUN2000 and the battery.
● The battery cables should be connected correctly. That is, the positive and
negative terminals of the battery connect to the positive and negative battery
terminals on the SUN2000 respectively. Otherwise, the SUN2000 may be
damaged, or even a re could happen.
● During the installation of the SUN2000 and battery, the positive or negative
terminal of the battery will be short-circuited to ground if power cables are not
installed or routed as required. In this case, an AC or DC short circuit may occur
and damage the SUN2000. The caused device damage is not covered under any
warranty or service agreement.
● The cabling distance between the battery and the SUN2000 should be less than
or equal to 10 meters, and within 5 meters is recommended.
Procedure
Step 1 Assemble the positive and negative connectors by referring to 5.5 Connecting DC
Input Power Cables.
● The battery voltage will result in serious injury. Use dedicated insulation tools
to connect cables.
● Ensure that cables are correctly connected between the battery terminal and
the battery switch, and between the battery switch and the SUN2000 battery
terminal.
Cables with high rigidity, such as armored cables, are not recommended as battery
cables, because poor contact may be caused by the bending of the cables.
Step 2 Insert the positive and negative connectors into corresponding battery terminals of
the inverter.
After the positive and negative connectors snap into place, pull the battery cables
back to ensure that they are connected securely.
