3.4 SLD - AC Cou led PV System with Back-u Power O eration
The single line diagram shown below is a re resentation of a ty ical installation configured for utility interactive
and back-u ower o eration, with AC cou led PV connected to a critical load anel. This drawing is a guideline
only, and is not a substitute for a code com liant installation. All com onents required for a code com liant
installation are the res onsibility of the licensed installer, including any additional circuit rotection requirements
not shown here.
NOTES
1. The backu ower bus must be electrically isolated from the main electrical bus. Do not ta the neutral wires of the main
and backu buses. A se arate line, neutral, and ground must be run to each of the load and grid orts of the battery
system. Refer to the installation manual for wiring details.
2. Energy meter su orts 1Ø and 3Ø configuration.
3. 3Ø service shown. For 1Ø service, do not o ulate R,S h com onents.
4. The battery system must be earth bonded to the building ground to meet lightning rotection requirements.
5. The battery system load and grid orts are inde endently controlled circuits. Should the electrical code require additional
“line-of-sight” disconnects, a se arate disconnect must be used for each of the grid and load orts. The disconnects
and/or circuit breakers must o erate inde endently of each other, and not be ganged.
6. The PCS rovides galvanic se aration of AC and DC sources. Overcurrent rotection devices, RCD Ty e A (300 mA), are
sufficient for rotection of both AC Grid and AC load orts.
7. Total AC name late of PV not to exceed 5 kW. String inverter shown for sim licity. Multi le AC strings of micro-
inverters ermitted. Any additional PV installed on the grid side of the battery system o erates inde endently from the
battery system, and is only limited by the interconnection requirements of the utility service rovider.
8. The maximum conductor size ermitted for the PCS grid ort is 16 mm
2
, and maximum breaker rating of 63 Am to
rotect the internal circuits of the PCS. The ESS breaker rating and conductor size can be reduced, however, these
arameters are subject to the total ossible continuous out ut current of combined PV and ESS generation at the ESS
grid breaker in the main electrical anel. Variables that determine conductor sizing include; PV continuous out ut current
rating connected to the ESS load terminal, total self-su ly current to the main electrical anel (load connected PV lus
ESS out ut), and length of run from the ESS grid ort to the main electrical anel (voltage dro ). Conductor sizing is the
res onsibility of the installer as er the actual installation, com liant to local / national electrical codes. Refer to the
technical data in section 16.1 for Maximum AC fault current and duration (short circuit).
9. The PCS short circuit withstand ca acity is rated at 10 kA (1 second). Circuit rotection must not exceed this rating.

6.2 Chassis Grounding
In this section, “Chassis Ground” is referred to as “ground” or “grounding” unless otherwise mentioned.
The PCS cabinet is shi ed with ungrounded DC ower terminals within the inverter. When terminated to the
batteries, the DC bus is configured for DC negative to ground.
AC Grid Earthing System: The AC ower grounding is achieved through the PE terminals of the AC grid connectors
on the AC Filter Board, as shown in section 6.1. The PCS is configured by default for a TN earthing system.
Note: The field ground wire rating applies to the AC circuit only . The DC source loo is internal to the battery
cabinet, and is rated accordingly.
DC ground fault monitoring: The Evolve BESS rovides integrated DC earth fault monitoring, and rovides
indication on the PCS anel as shown in section 12.2.
Lightning Grounding: The inverter has built-in lightning rotection. In order for the lightning rotection to be
effective, the grounding for lightning currents must be rovided via low im edance ath from the PCS PE terminal
to the building Ground/Earthing oint.
7 Energy meter installation
The energy management system’s solar self-consum tion algorithm requires the connection of an energy meter at
the customer’s main electrical anel. The meter must be installed and configured according to the electrical service;
either single hase or three hase. The information covered in this guide is generic to the a roved list of
integrated energy meters that are su orted by the home storage system at the time of your urchase. Refer to
the energy meter manufacturer’s installation manual su lied with your system for full installation details and
safety information.
Note: Refer to Appendix B for wiring diagrams specific to the manufacturer and model of the energy
meter supplied with your system.
The energy meter is su lied inside the PCS cabinet. It can be relocated within or adjacent to the main electrical
anel to sim lify the current and voltage wiring. Energy meters su lied with the home storage system are DIN
rail mounted. Use existing DIN rail s ace within the electrical anel, or add DIN rail as required.
7.1 Electrical connections – voltage measurement / ower su ly
The energy meter rovided is line owered from the electrical service. An in-line fuse, rated 1 Am / 250 VAC, is
required on the voltage line in ut to the meter. For three hase service, fuses are required on the V1, V2, and V3
in ut terminals. The voltage in uts can be connected anywhere on the customer side of the main service disconnect
breaker. For three hase systems, hase rotation is automatically configured by the meter.
7.2 CT (current transformer) connections
Note: Observe the current flow direction of the CT. The direction of flow must be away from the utility
meter. For three hase systems, hase rotation is automatically configured by the meter.
CAUTION! Handle CTs with care. Always terminate the CTs at the meter in uts rior to clam ing the
core onto a hot wire.

This system is su lied with s lit-core CTs for installation
without interru tion to the electrical service. The CTs must be
mounted on the rimary electrical bus, between the main
service breaker disconnect and the utility’s energy meter. This
is im ortant to ensure all loads and generation are ca tured for
o timum erformance of the solar self consum tion control
algorithms.
7.3 RS-485 communication connection
The battery system communicates with the meter using the
Modbus rotocol over an RS-485 network. Shielded twisted
air cable is required.
Note: Shield wire connected to earthing terminal at a
single oint only. Terminate the cable as shown

8 Droplet Ethernet connection to Home Router
sA Wi-Fi connection to the battery system is ermitted for remote monitoring of the system, however, a ermanent
connection is strongly recommended for reliable communication access to the system. The Ethernet wiring from
the battery system must be connected to a customer su lied router. A ermanent Ethernet connection to the
battery system requires external wiring. Com liance with local
electrical code is the res onsibility of the installer. Conduit and
fittings connected to this equi ment must ensure com liance with
the IEC environmental rating as er the equi ment ratings.
8.1 Ethernet cable connection
The Ethernet connection is a standard RJ-45 straight through
configuration. Standard EIA/TIA termination ractices are
recommended.
1. Remove the knockout dedicated for the Ethernet connection.
2. Secure the communication cable strain relief (conduit fitting, if
a licable).
3. Terminate the routed cable as a straight-through Ethernet
connection.
4. Test the cable rior to connection.
5. Connect the cable to the Dro let’s Ethernet ort as shown.

10 Start-up Sequence
CAUTION! Powering the Evolve home energy storage system requires a s ecific start-u rocedure.
Please follow the ste s below.
CAUTION! If the battery disconnect has been laced in the OFF osition at any time during o eration,
wait one minute before returning to the ON osition. Ra id cycling (less than one minute) of the battery
disconnect can cause damage to the re-charge circuit.
CAUTION! During the first start-u sequence after installation, the battery modules may require a
battery maintenance cycle to balance the SOC. This maintenance cycle requires a grid connection so that
the PCS can be commanded to charge the batteries. The PCS battery SOC alarm light will flash yellow if
maintenance and/or other battery faults are resent. This rocedure may take from a few minutes to a few
hours, de ending on the difference in battery module SOC. Please refer to the PCS Service Manual for more
information.
1. Remove the front cover from the battery cabinet
adjacent to the PCS cabinet.
2. Press the [Power] button (see above, label #8) on the
master battery module. The master battery module has
communication wired from the battery BMS ort (label
#4) to the PCS [BMS in] ort.
WARNING! When the batteries are turned ON, the
battery voltage will be resent at the ower anel
assembly bus bar where the battery modules are terminated.
his step may take up to one minute.
Verify that the indicators are as shown in “Normal O eration”
as shown below.
Battery Power Button
Operation
WARNING! The master battery
turns on all other battery modules in the
