WARNING
The input of DC voltage in the battery side of energy storage inverter
should be within the required range. Otherwise, the energy storage
inverter will not be able to operate.
When configure the quantity of battery series and parallel quantities,
the highest charging voltage and the lowest discharging voltage need
to be considered. For detailed information, consult qualified technical
service personnel.
PWS2-30M-EX does not include DC GFDI function, and the system
needs to configure BMS containing DC GFDI function.
WARNING
Only qualified professional can conduct wiring work.
CAUTION
Battery Types and Battery Management
The Inverter can operate with different types and models of batteries.
The battery is monitored and managed by the appropriate BMS, usually
specific to the make and model of the battery. For proper operation the
BMS must be compatible with the Sinexcel inverter.
The BMS passes on the appropriate battery charge-discharge
characteristics and settings to the inverter. The inverter in turn controls
the charge/discharge voltage and current and ensures that the
batteries are operated with the specified parameters and within the
appropriate limits.
For Lithium batteries the BMS is usually supplied by the battery
manufacturer. For Lead-acid batteries, it could be supplied by battery
manufacturer or anyone compatible verified by Sinexcel such as:

model OS-EB-P-xxx by Oztron Energy,

model AL-EB-CIMG_x.xx by Alpha ESS, and so on.
These EMS incorporates various features for microgrid and hybrid
operation and also includes the BMS suitable for Lead-acid batteries.
