4.3 RUNNING MODE DESCRIPTION
4.3.1 PCS + GENSET SYSTEM
PCS supplies power for load in VSG (Virtual Synchronous Genset) mode. When storage loading
power is greater than start power of scheduled genset or battery pack SOC is lower than cutoff
discharge SOC, genset will start. If genset and storage battery pack share the load, when load power is
lower than allowed storage charge power, genset will charge the battery pack with constant voltage and
frequency of storage rated charge power. When battery pack SOC is greater than cutoff charge SOC,
genset will not charge for battery pack, genset and storage battery pack share the load (NOTE: Converter
droop and genset droop should be set as same). When load power is lower than stop power of scheduled
genset, genset will stop.

ECONOMY MODE
If solar energy and storage energy supply power for load, when storage power is greater than
start power of scheduled genset or battery pack SOC is lower than cutoff discharge SOC,
genset will start. If PV outputs with max power, converter and genset share left load, when
load power is lower than PV output power, PV output power is limited, genset reverse power is
prevented and storage battery pack overcharge is prohibited. The solar energy takes load first,
only supplies power for storage battery pack when solar energy is sufficient. When load power
is lower than stop power of scheduled genset and battery pack SOC is greater than cutoff
charge SOC, genset will stop.
