1. GENERAL INFORMATION
1.1. Description of Storelio off-grid
Storelio off-grid solar systems convert photovoltaic DC
current to AC current to feed it in a dedicated local grid.
Excess current is temporary stored into aLithium battery for
later release.
1.2. Use of the manual
This manual is intended to be a guideline for a proper
installation and an effective and warrantied use of Storelio
off-grid. It includes:
Directions for installation, commissioning and
operation for qualified installers ;
Directions for operation and maintenance for users.
Installing Storelio off-grid requires qualified skills in
photovoltaic and electrical as well as detailed knowledge of
the content of this manual. The Following instructions
should be followed scrupulously.
This manual must be kept during the entire service life of
Storelio off-grid for further reference whenever necessary
1.3. Validity of this manual
This manual is valid for the following models:
Reference Model
ES301500-O 3000 Series
ES201500-O 2000 Series
1.4. Long storage precautions
Storelio off-grid battery is precharged before
shipment from easyLi factory. In case of storage
exceeded six months between easyLi factory
shipment and operation it is mandatory to recharge
the battery in compliance with the specific
procedure defined by easyLi. Any questions please
ask your easyLi authorized dealer.

2.2. Intended use of Storelio off-grid
Storelio off-grid is not intended for use by persons
(including children) with reduced physical
capabilities or lack of experience or knowledge.
Children should besupervisedto ensure that they
do not play with Storelio off-grid.
Storelio off-grid is designed as perthe applicablesafety and
technical guidelines and regulations. The electrical
installation of Storelio off-grid must comply with local
photovoltaic regulations and technical specifications
described in this manual.
easyLi unauthorized persons are not allowed to
open or attempt to repair Storelio off-grid.
Never install Storelio off-grid in dusty, accessible
to rain or liable to flooding areas as well as where
flammable products or potentially explosive gas
are stored.
Any use other than the one for which Storelio off-grid is
designed releases easyLi from any liability in case of
damage or injury.
easyLi is by no means liable of Storelio off-grid installation.
Therefore, easyLi liability cannot be involved in any default
and/or dispute regarding Storelio off-grid installation.
Products manufactured by easyLi cannot be qualified as
devices committing manufacturer’s joint liability.
2.3. Safety and installation precautions
Make sure that all wires are disconnected from
any power source during the entire installation
procedure of Storelio off-grid:
- solar panels (external PV switch)
- house grid (electric board)
Short circuit or reverse DC polarity causes
irreversible damages to Storelio off-grid that are
not covered by warranty.
Follow carefully all steps of the installation
instructions in order of succession as described in
this manual.
Comply with the range of DC input described in
the Chapter “Technical data” (60V / 150V).
Applying a higher voltage than specified causes
irreversible damages not covered by the
warranty. It is mandatory to take into account the
temperature correction coefficient in line with the
minimum environment temperature of the
installation. In case of missing information
regarding this coefficient, the continuous voltage
to be considered is equal to 1,2 times the open
circuit voltage.

3.3. Operating principles
Photovoltaic energy from PV panels is converted into
alternating current and feed in a dedicated house grid
powered by Storelio off-grid. Excess current is temporary
stored into the Lithium battery for later release.
Dedicated grid is made of electrical devices which
cumulated power must be lower than the maximum
authorized power of Storelio off-grid. Only this dedicated
grid will be powered by Storelio off-grid.
DANGER!
Never connect the dedicated grid to the main
house grid powered by the distribution grid. It
can cause irreversible damages not covered by
the warranty.
When electrical devices of the dedicated grid
are requiring more than the maximum power of
Storelio off-grid, the system will reach the
« overload » state and the electrical devices will
not be powered anymore. It is mandatory to
unplug some devices to come back to a total
power lower than the authorized one.
Storelio off-grid is equipped with an AC input. This input
must be connected after the house main current breaker
(see Figure 4). The available power of the AC input line
must be equal to the maximum power of Storelio off-grid.
Refer to chapter “Technical data”.
Figure 4
1. PV Input (+/-)
2. Battery box connection (provided cables)
3. AC Input
4. AC output (dedicated grid)
5. Main house breaker, connected to the distribution grid
Two operating modes are available:
« off-grid » mode
When the Lithium battery capacity level is over 0%, the
dedicated gridis powered by Storelio off-grid, from the solar
panels or the Lithium battery. This is the “off-grid” mode.
« grid » mode
When the Lithium battery is discharged and its level displays
0%, the dedicated grid is powered by the AC input line. This
is the “grid” mode.
3.4. Environment requirements and installation
precautions
Storelio off-grid must be mounted indoor
Do not expose Storelio off-grid to any direct
sunlight or any source of heat or excessive dust.
Storelio off-grid must not be accessible to
children.
- Storelio off-grid must be installed in a dry area, away from
rain. Do not let water penetrate inside Storelio off-grid.
- Mount Storelio off-grid vertically. The mounting surface
must be able to withstand Storelio off-grid weight (up to 35
kg).
- Storelio off-grid is heavy. Make sure to handle it with 2
persons while mounting it onto the wall plate.
DANGER!
In case of drop or significant impact marks on
Storelio off-grid, do not follow on the installation
and do not attempt to repair Storelio off-grid.
Contact your easyLi authorized dealer.
- Storelio off-grid must be installed with 20 cm vertical and
horizontal clearance.
- Ambient temperature is 0°C/+40°C
- Recommended operating temperature is +5°C/+25°C
Never apply a DC input voltage higher than
specified. This causes permanent damage to
Storelio off-grid not covered by the warranty.
3.5. Lightning protection
In solar photovoltaic installations, precautions must be
taken to avoid damages from lightning surge. Storelio off-
grid is not equipped with surge protection. Make sure to
comply with local applicable regulations. The use of an
external photovoltaic surge protection from lightning may be
required. Storelio off-grid damages caused by lightning are
not covered by the warranty.
