3. Use “▲” or “▼” to select the “Alarm History”, as shown in the above figure and press “ENT” to confirm.
If there is no historical alarm, the prompt will be “Alarm History: None”.
ALARM HISTORY
None
The historical alarms of the monitoring module are stored in cyclic order. Up to 200 alarms will be recorded. Above
that, the earliest alarm will be cleared automatically.

At the monitoring module, the displayed historical alarm information includes: alarm serial No., alarm name and alarm
start/end time (year, month, day, hour, minute, second).
If it is a rectifier that raised the alarm, the ID of that rectifier will be displayed.
4. At any Alarm History information page, press “ESC” repeatedly to return to the higher-level menus.

Discrepancy
If the DC Power System has shunts, the addition
of measured load current and Battery current
differs rectifier output current noticeably
