INTRODUCTION

Overview

This manual contains instructions for the operation of the Eguana Evolve™ home energy storage system. This product, when installed, is permanently wired to the home electrical panel.

There are two main components as shown below, including the energy storage system (1), and the energy meters installed in the main electrical panel (2). The system may include one or two meters, depending on the solar system that is installed.

This product is intended to operate in parallel with a utility connected solar PV system, and is designed to manage the consumption of utility and solar energy within the home. The system is capable of providing limited backup power to the home in case of a grid outage, as well as charge batteries from the solar system. A sample diagram below shows a typical layout of an AC coupled solar plus storage system

Your system may be installed in a manner differently than shown above. In addition, in accordance with your local electrical code, your installer may have included dedicated emergency disconnect switches for your battery and solar systems. Consult your system installer regarding the application and installation setup of your specific system. Refer to the Installer Checklist at the end of this document regarding information to be provided to you from your certified system installer.

The backup electrical panel shown is a dedicated electrical bus separated from the main electrical bus. While they are shown as two independent panels above, the backup panel may be co-located inside the main switchboard

System Monitoring – Account Setup

To view your system online, download the Stormcloud by SwitchDin app (available in IOS & Android) and enter the login credentials provided in the account invitation email issue by your installer. Alternatively, access the monitoring system via web-browser @ https://pwa.switchdin.com/account/login

Operation

The Evolve home energy storage system is fully automated. The EMS will be programmed to connect the system to the grid after AC and DC sources are applied. While the monitoring system provides a complete dashboard of your system’s operating state, the LED display on the front of the battery system can be used to determine its present operating conditions.

LED Display Indicators

The display panel provides indication of the following: Battery status (state of charge) System operating mode (out of) Service Indicator

To conserve energy, the LEDs will turn off after 5 minutes from being activated. They can be re-activated by pressing the service button

Charge = flash right. Discharge = flash left. Low battery
| | Sleep / Standby mode. Grid timing mode. Grid synchronization mode. Ten second test before grid connect mode. Grid connected mode.
| | System OK. System out of service. User initiated service mode.

Service Button
The service button can be used to wake the LED display, and either put the system into or out of service mode, as well as cycle through various operating modes.

IMPORTANT! In the event that the system has gone out of service, please consult your installer for guidance. Depending on the nature of the service fault, your installer may advise you to reset the system on your own, or schedule a service visit.

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, lighting, 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. A portable UPS is recommended for devices that require uninterrupted power.

IMPORTANT! Surge rated loads, ie) power tools, portable air conditioners, etc, 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. The power output / surge rating will be further limited when the battery is below 10% SOC.

IMPORTANT! 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.

Backup power display modes

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”.

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! Direct sunlight is required to charge the battery. If the battery system is installed without PV connected to the backup panel, do not attempt the restart. Wait for the utility power to return.

1. To increase the battery charge rate and/or prevent further discharge, shut off all home circuits in the electrical switchboard. The battery and solar PV circuits must be ON.

2. Press and hold the service button for 5 seconds.

3. The battery system will restart. The battery will begin to charge approximately one minute after the PV system is energized. If the battery does not begin to charge within 15 minutes of restart, it will shut down again.

4. Where home circuits have been shut OFF in step 1 above, allow the battery to charge to 10%, then turn ON the home circuits. The charge time is dependent on the amount of solar production.

Manually setting the battery minimum SOC reserve

The default minimum SOC reserve is set to optimize the system’s operation in a solar self-consumption mode. In the case of a scheduled grid outage, or a weather event which risks a grid outage, the battery minimum reserve can be manually set to its maximum value to maintain a full battery. Once the event and/or event risk has passed, the setting must be manually returned to the lowest value to return to solar self consumption mode.

Login to the SwitchDin Stormcloud app and follow the steps below to change the minimum SOC reserve.

Note: Settings changes require the battery system to be connected to the internet, and battery health = OK as shown in the health block within the Overview menu (see image below – step 2).

1. Select ‘My Battery’ (your battery unit’s name).
2.  Select Equipment in the bottom menu.
3. Select Devices (below Endpoint attributes).
4. Select EguanaPcs.
5. In the Settings window, enter the new SOC limit and select [Update].

Note: Max = 90

Note : Return the SOC limit to the Min value after the outage event and/or event risk has passed.

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 annually.

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. Contact your system installer as recommended below if any of the following conditions are present on the front display of the inverter panel.
