1 Solution Introduction
1.1 Networking Architecture
The C&I microgrid energy storage solution has the following networking
architectures: on/o-grid PV+ESS system and o-grid PV+ESS system.
NO TICE
In o-grid scenarios, the load requirements are as follows:
1. The instantaneous peak current (basic current + inrush current) upon load
connection and disconnection shall not exceed 1.1 times of the PCS rated
current.
2. The total rated capacity of all loads shall not exceed 2/3 of the PCS rated
capacity.
3. Motor load constraints: The load of motors that use direct on line (DOL)
starters or star-delta starters shall not exceed 10% of the PCS rated power. The
load of motors that use variable frequency drives or soft starters shall not
exceed 2/3 of the PCS rated power. If the PCS carries load, the load of motors
to be connected and disconnected shall be decreased accordingly in the same
proportion.
4. Isolation transformer: The isolation transformer equipped for the PCS must be
started together with the PCS. Do not start the PCS before switching on the
isolation transformer.
5. Transformers on the load side (excluding isolation transformers): The load-side
transformers less than or equal to 50% of the PCS rated power can be
connected and disconnected independently, and those greater than 50% of the
PCS rated power shall be started together with the PCS.
6. Even harmonic load constraints: When the excitation reactive power of the PCS
transformer reaches 2.5 kvar (2.5% of the PCS rated power), 2.5% even
harmonics (calculated based on the typical 200 kVA transformer parameters)
are allowed. When the excitation reactive power of the PCS transformer
reaches 5 kvar or above (5% of the PCS rated power), 5% even harmonics are
allowed. When the PCS has no output fundamental wave current, loads with
even harmonics cannot be connected.

1.1.1 On/O-Grid PV+ESS System
The on/o-grid PV+ESS system applies to C&I campuses where the power grid
capacity is insucient, capacity expansion is dicult, or power is limited during
peak hours.
In this system, the ESS is AC-coupled with the PV system through an isolation
transformer. The microgrid system is connected to or disconnected from the power
grid through an on/o-grid switch. When the system is o-grid, the ESS functions
as the main power supply to support the power grid, and also supplies power
together with the PV system to critical loads.
Figure 1-1 shows the networking architecture of the on/o-grid PV+ESS system.
Table 1-1 lists the components.

1.1.2 O-Grid PV+ESS System
The o-grid PV+ESS system applies to remote areas and islands without electricity.
The ESS and PV system are controlled and coordinated to supply power.
In this system, the ESS is AC-coupled with the PV system through an isolation
transformer. The ESS functions as the main power supply for grid forming, and
also supplies power together with the PV system to loads. When the ESS is
overdischarged, the DG charges the ESS.

1.2 Communication Logic
One SACU or SmartLogger manages multiple ESSs, PCSs, and SUN2000s, one
meter, and one IMD to form an array. Intra-array:
● The SUN2000s communicate with the SACU or SmartLogger, the IMD
communicates with the SACU or SmartLogger, and the meter communicates
with the SACU or SmartLogger over RS485.
● The ESSs communicate with the SACU or SmartLogger over FE in star or chain
topology.
● The PCSs communicate with the SACU or SmartLogger over FE in star or ring
topology.
● Maximum communication distance of the SACU or SmartLogger:
– RS485: 1000 m
– FE: 100 m
Select either of the following topologies based on the quantities of ESSs and PCSs
in the array as well as the deployment of optical bers.
(Recommended) Typical Scenario 1: SmartLogger+ESS FE Star+PCS FE Star
Topology
In this scenario, the SmartLogger3000A is congured, and the customer needs to
prepare one switch (quantity of 10M/100M auto-sensing Ethernet ports ≥ 8). The
quantities of switches and Ethernet ports are congured based on the quantities
of ESSs and PCSs connected to the array.
