4.2.3. Temperature Protection
Low/Over temperature protection in charging
：
When battery’s temperature is beyond range of
-5
℃
~+55
℃
during charging,
temperature protection is activated, device stops charging.
The protection is over when temperature back to rated working range.
Low/Over temperature protection in discharging
：
When battery’s temperature is beyond range of
-20
℃
~+55
℃
during discharging,
temperature protection is activated, device stops supplying power to the
outside.
The protection is over when temperature back to rated working range.
4.2.4. Other Protection
Short Circuit Protection
：
When the battery is activated from the shutdown state, if a short circuit occurs,
the system starts short-circuit protection for 60 seconds.
Self-Shutdown
：
When device connects no external loads and power supply and no external
communication for over 72 hours, device will dormant standby automatically.
Caution
Battery’s maximum discharging current should be more than load’s maximum
working current.
4.3. DIP switch
When the batteries are connected in parallel, the host communicates with the
slaves through the CAN interface. The host summarizes the information of the
entire battery system and communicates with the inverter through CAN or 485.
The connection mode is divided into the following two cases:
1-
The communication cable from the host CAN IN to the inverter comm port
should be the correct one.
2-
DIP configuration depending on Inverter type:
