Recommended battery configuration
Maximum capacity: In a single-node system, a maximum of six battery modules can be
•
connected. In a parallel system, a maximum of three power modules can be connected. Each
power module can connect to a maximum of three battery modules.
In a parallel system, three routes of single-phase output can be combined but they cannot
•
be used as three-phase output.
•
In a parallel system, the number of battery modules on the master and slave products must
be the same.
•
In a parallel system, if the number of battery modules on the master and slave products are
different (not recommended), the products with larger capacity may fail to fully discharge in
heavy load scenarios.
•
In a system with one power module and one battery module, when the ESS supplies power
independently, the load power cannot exceed 2.5 kW. If the load power exceeds 2.5 kW, the
ESS shuts down for 10 seconds and then restarts, which repeats for three times. The ESS runs
with a power limit of 2.8 kW for 1 hour and then stops working.
