2 INTRODUCTION
2.1 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.

2.2 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 issued
by your installer. Alternatively, access the monitoring system via web-browser @
https://pwa.switchdin.com/account/login
3 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.
3.1 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.

3.2 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.
5 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.

5.2 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.

7
5.3 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).
