1.1
Read these Installation and Operating Instructions thoro-
ughly in order to ensure that the SOLARWATT MyReserve
functions smoothly. Installation and service must be car-
ried out by qualied electrician who has been certied
by SOLARWATT. The installation and operating manual
should be stored in the vicinity of the SOLARWATT My-
Reserve and must be accessible at all times to everyone
involved in work on the storage battery.
With more than 20 years of production experience
under its belt, SOLARWATT is one of the pioneers of
the German solar industry. What started in 1993 as
a two-person company is now a leading manufactu-
rer of solar modules – a provider of intelligent ener-
gy solutions for both private and commercial uses.
The MyReserve battery storage system completes the sys-
temic approach of SOLARWATT. By choosing SOLARWATT
MyReserve, you will benet from a high-quality and inno-
vative product from the SOLARWATT family. The product
makes use of safe, highly ecient, ready to use battery
technology combined with excellent battery module exe-
cution. MyReserve also has a battery management system
that eciently connects and monitors all components.
This installation and operating manual enables you to sa-
fely and correctly integrate the SOLARWATT MyReserve
into a photovoltaic system so that this innovative battery
storage system can provide the optimal benet and thus
increase your household’s internal consumption.
These Installation and Operating Instructions apply to
SOLARWATT MyReserve 500, MyReserve 800 products
and MyReserve Extension from SOLARWATT GmbH.

1.4
The SOLARWATT MyReserve is a DC-coupled battery sto-
rage system installed between the photovoltaic system
and the inverter. There is no data exchange between
MyReserve and the inverter. With this DC connection,
MyReserve does not have a direct inuence on the net-
work quality. MyReserve can feed both single-phase and
three-phase inverters. Its AC Sensor records electrical po-
wer drawn from or fed into the public grid. These variab-
les are evaluated in order to determine the power output
of the battery storage. More or less power is transferred to
the inverter depending on household consumption.
As such, when the system is running entirely in battery
mode (at night), rather than feeding electrical energy into
the grid, the MyReserve will regulate the system so as to
maximize consumption of self-generated electricity. Du-
ring the day, the MyReserve will output battery power in
such a way that the system draws as little energy from the
public grid as possible, and draws in enough power to en-
sure that the battery is charged completely by sundown.
This charging and discharging behavior protects the lit-
hium ion cells and maximizes the service life of the My-
Reserve.

ved. Using the MyReserve improperly or for purposes
other than the intended one can result in product mal-
functions and/or life-threatening situations. and renders
the warranty null and void.

MyReserve is a compact battery system with lithium ion
technology-based cells. MyReserve is installed in the
DC string between the PV system and the grid-opera-
ted PV inverter. This means that both single-phase and
three-phase PV inverters can be integrated in the overall
system. MyReserve is suitable for existing systems as well
as new systems. This gure shows the layout of the sys-
tem in a simplied diagram.

The smallest expansion level of the MyReserve has a ra-
ted capacity of 4.4 kWh and only requires one housing
(base system). An additional housing for installing additi-
onal battery modules is required for all other expansion
stages (SOLARWATT Extension 2.2 and 4.4).
Please observe that you must order AC Sensor 63 in addi-
tion to the system for this purpose. It is not automatically
included in the scope of delivery.

Always use the SOLARWATT MyReserve string con gurator tool for system planning.
The con gurator is available in the „Professionals“ area
of our website www.solarwatt.com.au under the menu
item "Tools".
For systems with SOLARWATT system inverters and
Stecagrid inverters ensure that the con guration
ratio of the inverter rated output to the PV system
size does not exceed 110 %.
Example:
3 kW Inverter 3,5 kWp PV-System --> not ok
3 kW Inverter 3,2 kWp PV-System --> ok.
In systems using the SMA TL21 of the „Sunny Boy“ inverter series, it must be ensured that the maximum open
circuit voltage does not exceed 530 V and the maximum MPP voltage does not exceed 500 V.Based on the par-
ticular MPP tracking mechanism of this series, short-circuits will occur at voltages above 500 V, which can result
in defects of the MyReserve and the SMA inverter. A system installation that does not match the speci cations of
SOLARWATT will void any warranty claims.
In systems with the SMA Sunny boy 2.5 Inverters, the Optirac Global peak tracking must be switched o via the
Bluetooth interface integrated in the inverter. Faulty charging and discharging behavior of the MyReserve can
occur if this is disregarded..

• Max. relative air humidity: 85%. Do not expose My-
Reserve to environments with higher humidity levels.
• Optimal ambient temperature range: 0°C to 30°C;
max. permitted ambient temperature: 45°C.
• Keep the product out of direct sunlight.
• For the 4.4 kWh design, the wall and the mounting
material must have a static load-bearing capacity of
at least 80 kg.

pacities), oil or wood storage depots, barns, sheds, etc.
NOTE
MyReserve does not operate at temperatures below -15°C or above +45°C. Unrestricted performance is pro-
vided for the household in the temperature range of 0°C to 30°C. Accelerated aging of the cells should be
taken into account at temperatures above +45°C.

The smallest extension stage of MyReserve only requi-
res a housing. In order to make installing the MyReserve
as convenient as possible, leave su cient room around
the battery storage system to feed cables and optimally
mount the housing cover.
Minimum clearance above and below: 20 cm
Minimum clearance to the right and left: 5 cm
Use the adjacent gure or wall mount included in the
delivery to mark the holes on the wall (3x). The wall
holder must be fastened to the wall with three screws.
There are two alternative holes in the wall mount for
each of the three screws. Only use wall mounts approved
by SOLARWATT for the installation.
Horizontal installation
Lift the unit on the wall mount using the handle (1). Look
through the opening in the rear side to see whether the
body slides securely into the wall mount and fastens in
place there automatically. Secure the housing against un-
intended removal with a screw connection at one of the
three asymmetrically arranged holes (2). All fastening ho-
les have a diameter of 9 mm. Remove the two screws (3)
and lift o the cover to expose the terminal strip.

minimum clearances from other devices.
The cable that connects the battery module of the exten-
sion to the MyReserve base unit is 6 m long. This determi-
nes the maximum possible distance between MyReserve
