6.1 AC power connections
This battery system contains two independent AC power connection ports; one port dedicated for an electrical utility
connection, marked “AC Grid”, the other port dedicated for backup operation, marked “AC Load”. This product’s primary
application is intended for utility interconnection, and must be connected to a utility electrical service supplying split
phase 240/120 Vac, 60 Hz. The backup operation of this product is a secondary application, and is intended to supply
emergency backup operation only.
Note: The PCS provides galvanic separation between AC
and DC Sources.
CAUTION! To reduce the risk of fire, connect only to a
dedicated circuit provided with appropriate branch circuit
over-current protection in accordance with local electrical
codes.
WARNING! Improper connection of the wiring panel may
result in equipment damage and cause personal injury.
Disconnect all AC and DC Sources prior to installation.
CAUTION! The AC grid and load ports are independent
circuits, controlled internally by an automatic bypass and
transfer switch. Each port must be connected to
electrically isolated panels. Tapping line or neutral wires
from the main electrical panel to the backup panel may
result in permanent damage to the product.
AC Grid Port:
1. Open the spring clamp terminals on the AC
circuit board at the port marked “AC Grid”.
2. Terminate the AC grid connection wires as
follows: “L_Grid” = Line, “N_Grid” = Neutral, and
“PE” = Ground.
3. Close the spring clamp terminals, ensuring levers
are fully engaged.
AC Load Port:
1. Open the spring clamp terminals on the AC
circuit board at the port marked “AC Load”.
2. Terminate the wires at “L_AC load” (Line),
“N_AC load” (neutral), and “PE_AC load”
(protective earth).
3. Close the spring clamp terminals, ensuring levers
are fully engaged.
Figure 7: AC wiring.


6.2 Chassis Grounding
In this section, “Chassis Ground” is referred to as “ground” or “grounding” unless otherwise mentioned.
The AC and DC grounding are intended to provide a low impedance signal path at all frequencies.
DC Ground Wiring Installation: The PCS cabinet is shipped with ungrounded DC power terminals within the inverter.
However the default setting for DC grounding is set for DC negative to ground. This is to indicate that the DC negative
terminal of the inverter is grounded within the PCS system. The DC negative ground is completed once terminated in
the master battery cabinet, as the battery module DC bus is pre-wired with negative grounded battery modules. .
AC Ground Wiring Installation: The AC power grounding is achieved through the PE terminals of the AC grid
connectors on the AC Filter Board, as shown in section 6.1.
Note: The field ground wire rating applies to the AC circuit only. The DC source loop is internal to the battery
cabinet, and is rated accordingly.
Lightning Grounding: The inverter has built-in lightning protection. In order for the lightning protection to be effective,
the grounding for lightning currents must be provided via low impedance path from AC Filter Board to System Ground
and further to the building Ground/Earthing point.
6.3 Communication Wiring to the Energy Management System –RJ45 Pin-out
The Evolve ESS communicates with the energy management system using the Modbus protocol over an RS-485
network. Shielded twisted pair cable is required.
Note: The EMS panel supplied with the ESS includes a 10 ft factory prepared cable. Should the installation require
further separation between the EMS panel and the Evolve PCS cabinet (ACB05U-LP), a cable can be prepared using
CAT 5 shielded wire, with an RJ-45 connector terminated at the PCS end only. Connect the shield to the EMS end
only.

Refer to section 11 –Troubleshooting if the service button does not perform the action requested.
9.4 Backup Power Operation
This system will provide backup power to dedicated electrical circuits within the home via a permanently wired
electrical sub-panel, referred to as the backup panel. Backup power is limited in rating and duration, both of which are
dependent on the nature of the loads connected to the system, and the availability of the solar PV supply. This system
is designed to reliably provide power to a refrigerator, home lighting, home electronics, and small appliances.
NOTE: This product is not an uninterrupted power source (UPS). Following a utility outage, a four second power
interruption will occur before the backup power source commences. As a result of this interruption, a desktop or
portable UPS is recommended if continuous operation is desired for any electronic devices.
IMPORTANT! Surge rated loads, ie) power tools, portable air conditioners, may cause an overload shutdown.
Equipment of this type that is connected to the backup panel should be inspected and tested regularly as per
manufacturer suggested schedules. Permanent damage to the battery system and/or your equipment may occur if
exposed to chronic overloading cycles.

IMPORTANT! Portable extension cords connected to a backup circuit should be limited to 10 meters.
IMPORTANT! This product does not support automatic gas generator integration. Do not attempt to connect a gas
generator to the battery system. If generator support is required, consult your installer regarding a separate manual
transfer to your backup electrical panel.
NOTE: The power output / surge rating will be further limited when the battery is below 10% SOC.
9.4.1 Backup Power Display Modes

Battery status LEDs indicate the following:
Charge = flash right. Discharge = flash left.
PCS and service lights off.
Low SOC shutdown in backup mode. See section 5.2 to restart the system.
Low SOC shutdown initiated while out of service. See troubleshooting –section 7,
“service light on in backup mode”.
9.5 Restarting the battery system after low battery shutdown
The system will shutdown when the battery reaches a critically low level during backup operation.
To restart the system:
IMPORTANT! Ensure there is adequate sunlight for the solar PV system to charge the battery before restarting
the system. If the battery system is installed without a PV system connected to the backup panel, do not attempt to
restart the system. Wait for the utility power to return.
1. Press and hold the service button for 5 seconds.
The backup power will restart, allowing the PV system to
reconnect* and begin charging the battery. The system will continue to operate if the battery charges to its minimal
normal operating range. If the battery does not charge within 15 minutes of restart, the system will shut down to
preserve the battery.
*PV system reconnect time is approximately 5 minutes.
Note: If necessary, the load circuits can be shut off inside the backup panel to increase the battery charge rate. Do not
shut off the PV circuit.
10 Maintenance
The Evolve ESS is a maintenance free product. Regularly scheduled inspection of the airflow path for the active
cooling fans on the bottom side of the PCS cabinet is all that is required. This inspection should occur on an annual
basis, or coincide with PV inspection.

16
If the fan ventilation holes are obstructed with dust / debris, a soft-bristled brush can be used to wipe them clean. For
heavy soiling use a soft, dry brush. Do not use any solvents, scouring, or corrosive materials to clean the unit. Never
remove or unplug connections or plugs during cleaning.
11 Troubleshooting
System faults are reported and logged in the monitoring system. All fault logs are also accessible remotely by your
installer.
IMPORTANT! Contact an Eguana service representative as recommended below only after any of the following
conditions are present on the front display of the inverter panel, and the recommended actions do not resolve the
issue.
Condition
Definition
Service light ON in
grid mode
System is prevented from normal operation due to internal fault. Notify service personnel.
Service light ON in
backup mode
If the system faults into service in backup operating mode, there may be an overload condition
which prevents the system from operating safely. If the battery charge level is greater than
20% (one or more Green LEDs), reduce the load by shutting off circuits in the backup electrical
panel, then press and hold the service button 5 seconds to resume backup power operation. If
the battery low SOC shutdown mode is displayed, shut off all load circuits (keep PV ON) in the
backup panel, and do not attempt to resume backup operation until adequate sunlight is
present to provide a solar charge of the battery.

This indicates loss of both AC And DC power sources to the PCS. Check the circuit breaker in
the main electrical panel for the energy storage system.
Online monitoring
system not
accessible
Check the internet connection. If connection is via wi-fi, reboot the wireless router, and make
sure the login user and password have not been changed since time of original installation.
Check power to the energy management system via the orange indicator light on the right side
of the panel. Note: the energy management system may lose power after an extended utility
outage where there is not enough solar generation to maintain battery system power.
Note: monitoring system servers may occasionally be down for service. If first attempts are not
successfully, try again the following day before contacting your installer.
