2 INTRODUCTION
2.1 Overview
This manual contains instructions for the operation of the Eguana Evolve™ home energy storage system.
This product is intended to operate in parallel with a utility connected solar PV system, and is designed to
optimize the delivery of utility or solar energy within the home. The system is capable of providing limited
backup power to the home in case of a power outage, with the ability to charge batteries from the solar PV
system.
A sample diagram below demonstrates a typical layout of an installed system. The energy storage system
consists of two main components:
1. Evolve ESS: includes the power control system (PCS), and the battery.
2. Evolve Hub : includes equipment which,
connects the monitoring system to the home’s internet connection,
manages electricity flow to the home’s electrical loads from a combination of solar, battery,
utility power sources, and,
provides the automatic transfer to the home’s emergency backup loads during a power
outage.
Note: The system will require additional equipment to complete the installation, as supplied by the electrical installer. .
Safety shutdown switches may be added to your installation in order to comply with electrical code requirements –see
[A] below. Systems that support emergency backup power will require a dedicated electrical sub-panel –see [B]
below.

3 System Monitoring
The system can be viewed online at www.mypowermyway.com. You will receive
an automated invitation to setup your account after the installer has completed
the system installation.
From the monitoring system, you will be able to:
Monitor your solar, battery, and home energy
consumption.
Manually adjust the emergency battery reserve
capacity.
For a complete tutorial on the monitoring system,
login to your account, and select tutorial in the
support widget at the center of the dashboard
menu.
3.1 Setting the emergency reserve capacity
The default operating mode of the system will be set to
maximize energy savings while the utility supply is
operating; either through a time-of-use plan*, or via a
solar self consumption plan . While in this operating
mode, the battery capacity’s default partition will assign
75% of the battery for daily energy savings, and 25% for
emergency backup power.
* where applicable.
In the event of a planned utility outage, or due to an
extreme weather event forecast, the battery reserve
capacity can be changed to prioritize the entire battery for
emergency backup power use.
1. Click on the gear icon at the top-right of the
Battery Reserve widget.
2. Click the “Enable Emergency Power Reserve”
drop-down list, and select the desired duration.
3. Click on the save button to update the settings.
The battery will return to the default mode after the
selected day/week duration expires. Manual updates will
be required if “until disabled” is selected.

4 Operation
The system automatically runs the default energy savings
mode after the system is powered. The monitoring
system provides online access to the battery. With loss
of internet, the operating state can be viewed on the front
panel of the battery system.
4.1 LED display indicators
The PCS display panel indicates the following:
Battery state of charge (SOC)
PCS operating mode
Service mode
4.2 LED display definitions.
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, 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.

“service light on in backup mode”.
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! 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.
