BATT1 System
voltage error
①Check whether the battery
voltage matches the
controller's working voltage.
② Please change to a
suitable battery or reset the
working voltage.
① System voltage alarms when
using the Lead-acid battery for the
BATT1.
② System over-discharge alarms
when the BATT1 is set as 24V
battery type. Its actual voltage is
12V.
③ System over-voltage alarms
when the BATT1 is set as 12V
battery type. Its actual voltage is
24V.
Incorrect
wiring--connect
BATT1 first and
then BATT2
① Disconnect the system,
and reconnect the BATT2
first, then reconnect BATT1
②③BATT1 voltage should be
the same as the controller's
voltage level
