CAUTION! The PCS cabinet weighs up to 65 kg, and the battery cabinet weighs up to 102 kg.
Handle with care. The wall must be load-bearing rated according to the local building code.
Mechanical lifts are recommended to position cabinets on the wall bracket.
3.1 Locating the system

1. The installation location must comply with the environmental rating of the product. Refer to the environmental ratings in section 16.2 of this manual.
   CAUTION! Do not install in direct sunlight. Battery performance is dependent upon operating ambient temperature. Radiant heat absorbed in direct sunlight will greatly  reduce the performance of the battery, and will prematurely cause degradation of the display indicator panel on the PCS cabinet. The battery modules are rated for full power operation between -10C to +45C.
2. The forced air cooling of the PCS cabinet is from bottom to top. Refer to figure 1 for recommended layout plan.
3. All inter-cabinet cabling is limited in length. Separating cabinets is not permitted.
4. Wall mounting hardware not included. The load-bearing wall bracket is provisioned for M8 hardware. Levelling brackets are provisioned for M5 hardware.

3.2 Installation Area Required to Wall Mount PCS and Battery:
The physical installation of the cabinets requires the layout planning and installation of the system components in the available installation space. The recommended installation height is driven by the viewing angle of the display panel on the PCS cabinet.

3.3 Installation plan – power and communication circuits
The following example outlines the conduit plan for power and communication circuits for the battery system. In this example, the PV inverter is coupled to a backup power sub-panel. The sub-panel may also be an isolated power bus within the main electrical panel.

* The battery system is rated 5 kVA maximum. Solar self consumption prevents battery power export, however, the grid power circuit must electrically accommodate the total of both battery and PV generation when PV is connected to the backup circuit.
3.4 SLD – AC Coupled PV System with Back-up Power Operation
The single line diagram shown below is a representation of a typical installation configured for utility interactive and back-up power operation, with AC coupled PV connected to a critical load panel. This drawing is a guideline only, and is not a substitute for a code compliant installation. All components required for a code compliant installation are the responsibility of the licensed installer, including any additional circuit protection requirements not shown here.

Figure 3: Single Line Diagram: Typical AC coupled PV system.
NOTES

1. The backup power bus must be electrically isolated from the main electrical bus. Do not tap the neutral wires of the main and backup buses. A separate line, neutral, and ground must be run to each of the load and grid ports of the battery system. Refer to the installation manual for wiring details.
2. Energy meter supports 1Ø and 3Ø configuration.
3. 3Ø service shown. For 1Ø service, do not populate R,S ph components.
4. The battery system must be earth bonded to the building ground to meet lightning protection requirements.
5. The battery system load and grid ports are independently controlled circuits. Should the electrical code require additional “line-of-sight” disconnects, a separate disconnect must be used for each of the grid and load ports. The disconnects and/or circuit breakers must operate independently of each other, and not be ganged.
6. The PCS provides galvanic separation of AC and DC sources. Overcurrent protection devices, RCD Type A, are sufficient for protection of both AC Grid and AC load ports.
7. Total AC nameplate of PV not to exceed 5 kW. String inverter shown for simplicity. Multiple AC strings of microinverters permitted. Any additional PV installed on the grid side of the battery system operates independently from the battery system, and is only limited by the interconnection requirements of the utility service provider.
8. The maximum conductor size permitted for the PCS grid port is 16 mm 2 , and maximum breaker rating of 63 Amp to protect the internal circuits of the PCS. The ESS breaker rating and conductor size can be reduced, however, these parameters are subject to the total possible continuous output current of combined PV and ESS generation at the ESS grid breaker in the main electrical panel. Variables that determine conductor sizing include; PV continuous output current rating connected to the ESS load terminal, total self-supply current to the main electrical panel (load connected PV plus ESS output), and length of run from the ESS grid port to the main electrical panel (voltage drop). Conductor sizing is the responsibility of the installer as per the actual installation, compliant to local / national electrical codes. Refer to the technical data in section 16.1 for Maximum AC fault current and duration (short circuit).

	Low SOC shutdown initiated while out of service. See troubleshooting – section 7, “service light on in backup mode”.

12.5 Off-grid mode: Restarting the battery system after low battery shutdown
The system will shut down when the battery reaches a critically low-level during backup operation.
To restart the system:
IMPORTANT! If the battery system is installed without a PV system connected to the backup panel, do not attempt to restart it. For systems with backup panel connected PV, ensure there is direct sunlight for the solar PV system to charge the battery before restarting the system. Wait for the utility power to return.

1. Press and hold the service button on the front of the display panel for 5 seconds.

The backup power will restart, allowing the PV system to energize and charge* 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.
*Australia – the PV system begins to generate one minute after being energized.
Note: De-energize any home loads by shutting off the circuit breakers in the eletrical switchboard to increase the charge rate of the battery from the solar PV array. Do not shut off the PV or battery circuits. It is strongly recommended to charge the battery to a minimum of 10% state-of-charge before energizing any home loads.
The charge rate of the battery is dependent upon the available solar PV output. As a general rule, the battery will charge to 10% SOC at the following rates:

Maintenance

The Evolve home energy storage system 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.
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.

Troubleshooting

System faults are reported and logged in the monitoring system. All fault logs are also accessible remotely by your installer.
IMPORTANT! Contact your system installer immediately if any of the following conditions are present on the front display of the inverter panel.

Serviceable Parts – Battery module removal/replacement

The battery modules within the battery cabinet are removable and/or replaceable. To replace or remove the battery modules:

1. Follow section 5 in this manual to disconnect the inter-cabinet cabling.
2. Refer to the 68006 Battery Module Field Assembly Guide for instructions on removing the battery modules. Assembly and disassembly are the reverse order.
