● You are advised to use the SmartLogger WebUI.
● If Door Status Alarm is generated, check whether the cabinet door is open. If yes, close
the door.
● If ESU Communication Failure is generated, check whether communications cables are
connected correctly and whether the power supply is normal.
If a water alarm is generated, the water sensor is properly connected. In this
case, the water alarm will be cleared after the short circuit is removed.
If no water alarm is generated, check whether the water sensor cable is
connected properly.
Time-of-use (TOU) with capacity limit:
When the capacity limit is enabled in TOU mode, the charge/discharge time
set in the TOU window must cover 24 hours a day. Capacity limit is not
supported in non-charge/discharge time.
Capacity limit:
– If the capacity limit is met 24 hours a day, the ratio of the ESS/PCS to the
load power must be properly set to ensure that the ESS/PCS have
sufficient capacity to meet the capacity limit.
– When the ESS is used only for capacity limit, you can set the charge time
to 24 hours through the TOU setting. Do not set the discharge time and
non-charge/discharge time.
– The overload capability of transformers, power distribution switches, and
cables must be greater than the sum of the maximum charge current and
maximum load current of the ESS.
