Characteristics of MyReserve

More usable solar energy

PV (photovoltaic) modules produce direct current (DC)

and batteries store electricity in DC as well. Households,

however, use alternating current (AC). The DC power must

be converted to AC power and this conversion is perfor-

med by the inverter. Electricity from the roof goes through

an inverter and is converted into alternating current. If it

is sent to a conventional battery, it is converted back into

direct current. Then as the battery discharges the current

must be converted once again to alternating current. With

each conversion you lose some of your precious solar po-

wer. MyReserve, on the other hand, is installed before the

inverter. It stores the direct current from the PV system.

Only when the electricity is consumed in the household

is it converted into alternating current. This leaves over

90 % of your own solar power available – that pays o !

Highest reaction speed

In the best case, battery storage systems react without

delay to changes in solar power generation or household

consumption. Many electrical appliances only draw po-

wer for a few seconds. So if in reality it can take sever-

al seconds for a battery storage device to react to such

changes, the charging and discharging capacity of the

battery will lag behind the real power balance. Until the

storage device delivers energy, the devices consume ex-

pensive mains power. This has a long-term impact on the

e ciency of the battery. MyReserve is programmed for a

very high response speed, so that it can really serve the

power requirements e ciently. MyReserve therefore has

a reaction time 10 times faster than other systems. This

means increased power consumption and maximum e -

ciency. MyReserve registers the power demand immedia-

tely and delivers stored energy almost in real time. Thus

less power from the mains is needed.

Data security

Most conventional batteries rely on an Internet connecti-

on which means that digital intrusion is always possible.

To exclude manipulation by third parties, the internal and

external CAN data buses in the MyReserve are physically

separated. Data about device status is the only sort My-

Reserve transmits externally. The inner physical interfa-

ces protect the remaining data 100 % from anauthorized

external access. This ensures that no one can manipulate

your battery from the outside.

Long service life and warranty

The charging and discharging processes are intelligently

controlled via the battery management system in your

MyReserve. This increases the service life of the MyReser-

ve. SOLARWATT can therefore give you a 10-year perfor-

mance guarantee on the battery modules. If their usable

energy content falls below 80%, SOLARWATT will cover

the costs of replacement, transport, installation and re-

moval. During this period, the warranty covers an unlimi-

ted number of cycles (one-time complete charging and

discharging). SOLARWATT also o ers a 5-year product

warranty on the power electronics of your MyReserve.

The additional free FullCoverage* covers the risk of mains

overvoltage, lightning, theft and  ooding for 5 years.

* FullCoverage insurance is available only in selected countries.

Individuality through modularity

MyReserve  ts your requirements because its modular

design allows it to be con gured individually. Five battery

modules can be connected per MyReserve Command:

5x 2.4 kWh = 12 kWh usable energy content

5x 800 Watt = up to 4 kW charge/discharge power

You need more capacity? MyReserve can be expanded as

a cluster to a storage system with up to 60 kWh usable

energy content.

The capacity of electricity storage batteries is expressed in kilowatt hours (kWh). 1 kWh means that the

battery could power a device with an output of 1,000 watts for 1 hour. However, most devices require much

less than 1,000 watts. Here are a few examples of how much energy your battery can provide:

Charging behavior

Your SOLARWATT photovoltaic system produces electrici-

ty throughout the day. MyReserve stores the extra energy

your household does not consume directly, and makes it

available when the sun is not shining.

Extra PV energy is used to charge your

MyReserve.

Charge management “fully charged at sunset”Energy consumption of the household

MyReserve determines the optimum charging and dischar-

ging times using a self-learning algorithm that processes

energy generation and energy consumption in the house-

hold. This is because if the battery switches to “charging”

early in the day, it may remain at maximum charge for lar-

ge parts of the day. The cells age faster and the lifespan

of the battery is reduced. The charging strategy of MyRe-

serve therefore aims to ensure that the 100% charge sta-

te is not reached until shortly before sunset. MyReserve

“learns” from the yield and consumption data of the last

seven days and then optimizes the charging behavior. The

graph shows a comparison of the charging curve of con-

ventional batteries and the MyReserve.

MyReserve

conventional battery

Depending on the situation, MyReserve switches among

the following types of functions:

1. Direct supply from PV

2. Direct supply from PV and charge battery

3. Direct supply from PV, charge battery, infeed

4. Direct supply from PV and discharge battery

5. Discharge battery only (night mode)

Direct supply from PV

When your household requires exactly as much power

as your PV system is supplying (1 kW household, 1 kW

generated), you need neither purchase energy from the

public grid (0 kW electricity purchase) nor feed it into the

grid (0 kW infeed).

All of the energy produced is used directly (1 kW internal

consumption); MyReserve neither charges nor discharges

(0 kW battery charge/discharge).

This constellation is typical during early morning or late

evening hours.

Direct supply from PV and charge battery

If the PV system generates more energy than your house-

hold requires (2 kW generated, 1 kW household), the My-

Reserve will begin charging automatically (1 kW battery

charge).

The system will automatically adjust how the MyReserve

is charged in accordance with the charging strategy.

This constellation is typical around midday on sunny days.

Direct supply from PV, charge battery, infeed

In the example shown, 1.5 kW of energy are fed into the

MyReserve. If more energy is produced (3 kW) than can be

stored (1.5 kW) or used by the household (1 kW house-

hold), the excess electricity is fed into the public power

grid (0.5 kW infeed).

This constellation is typical on, for example, sunny after-

noons.

Direct supply from PV and discharge battery

The power generated by the PV system (1.0 kW) is less

than what the household requires (2.0 kW). MyReserve

discharges the electricity needed to cover household

needs (1.0 kW).

This constellation is typical for late afternoons.

Discharge battery only (night mode)

Whenever the PV system is incapable of generating po-

wer, the necessary electricity is primarily drawn from the

MyReserve. Only a small fraction must be purchased from

the power company. This constellation is typical for night-

time operations.

Sleep mode (winter operation)

If no electricity can be generated over a longer period of

time, for example because the PV system is covered in

snow, the MyReserve switches into energy-saving mode

in order to prevent deep discharge of the battery modules.

This mode, known as Sleep Mode, helps ensure optimal

protection of the battery modules. The battery modules

will remain capable of switching back into normal ope-

rating mode easily and automatically for a period of ve

months. If this ve-month time limit is exceeded, the bat-

tery modules can be re-activated by a service technician.

MyReserve operation

Temperature behaviour

NOTE

• There are no limitations on performance for the household in the range from 0°C to 30°C.

• On +5°C and colder there is a gradual throttling while charging.

• Operation does not take place below -15°C or above +45°C.

• Accelerated aging of the cells should be expected at temperatures above +45°C.

NOTE

-15 0 30 45

°C

MyReserve is not actively cooled and is therefore main-

tenance-free. There are no disturbing noises and the ope-

ration of the storage unit does not require any additional

energy through cooling. The MyReserve Command cools

down via the surface of the aluminum housing and trough

the room temperature.

A heat development of 60°C can occur on the MyReserve

Command.

LED indicators for Status

The bottom side of the MyReserve has LED indicators for

Status and Performance. Check the indicators at any time

for information regarding device status and current char-

ging state. See chapter “Troubleshooting” for information

on what to do in case of malfunctions—that is, if the Sta-

tus LED lights up red or red/yellow. The illustration shows

you the dierent possible LED indicators and what they

mean.

MyReserve Monitoring

There are three ways to visualize and monitor MyReserve data:

1. via Bluetooth with the MyReserve App

2. via network integration with the MyReserve App and the MyReserve Portal (remote maintenance service possible

via SOLARWATT)

3. via network integration with the EnergyManager from SOLARWATT - monitoring of all energy  ows in the house-

hold and comprehensive energy management

Via Bluetooth with the MyReserve App

Bluetooth

The MyReserve App can be used within the Bluetooth range of the MyReserve and customers can see:

• the generation of the PV string connected to MyReserve

• the charging and discharging power of the MyReserve

• the SoC (State of Charge)

• the feed-in power or the supply from the grid

NOTE

For Bluetooth communication MyReserve uses a point-to-point connection. So connecting is only possible

between two devices. If you like to use the MyReserve app in your entire home network, your installer has to

connect your MyReserve to the PowerDataGateway (PDG), see page 17.

The network integration of MyReserve takes place via

the PowerDataGateway (PDG). MyReserve Command and

PDG are connected via Bluetooth interface.

Due to the network integration the MyReserve App is

easy to use in your entire network.

In addition monitoring data from MyReserve can be vie-

wed via a web interface, the MyReserve Portal.

Access to the portal is via the URL:

https://myreserve.solarwatt.com

The MyReserve Portal enables:

• The mobile visualization on the road

• Extended service through remote maintenance for

rapid and uncomplicated error analysis through

SOLARWATT

Your installer will explain to you how to register on the

MyReserve Portal and will give you the MyReserve serial

number that you will need to complete the registration

process.

By registering you also have access to the the privacy po-

licy for the portal. You can always be sure that your data

is kept strictly con dential.

NOTE

The MyReserve app cannot be used simultaneously via Bluetooth and network connection.

NOTE

Via network integration with the EnergyManager

If you are using your MyReserve in combination with the

EnergyManager, you can access the EnergyManager Portal

to view and evaluate all energy  ows within your house-

hold in real time.

MyReserve transmits energy data, such as electricity in-

put and output or charging status, to the EnergyManager.

The EnergyManager Portal visualizes data over the course

of the day for the current day as well as all previous days

and gives you detailed information on electricity gene-

ration and consumption, or device charging and dischar-

ging, at any time.

By using the QR code above or via the website www.solar-

watt.com, menu item Energy Management, you can get to

know and test the EnergyManager Portal.

Ask your SOLARWATT installer! He will set up your Ener-

gyManager Portal login.

Scan the QR code to get to

know the EnergyManager

Portal!

Troubleshooting

The MyReserve’s Status LED will light up red or red/yel-

low to indicate any malfunctions. Under certain circum-

stances (and after consulting with your installer), some

error codes can be resolved by simply restarting the

system manually. To do this, interrupt the power supply

to the MyReserve by unplugging the power supply from

MyReserve Command , wait 60 seconds, then switch the

power on again.

This illustration shows the various error codes and what

they mean.

NOTE

Due to the interaction of the entire system, several error codes may also be displayed simultaneously. Accor-

dingly, the error code then consists of several error messages together.

NOTE

After a restart of MyReserve, an initialization with calibration and check of the start conditions takes place (a

PV-surplus must be measured once).

Unloading will not occur until the following day after MyReserve has detected a minimum surplus of PV energy.

NOTE

MyReserve critical states

If any of the following critical situations develop, open a window, immediately leave the installation location, close the

door, and then call the emergency services.

and limb.

Fireghting measures

In the event that the battery is exposed to excessive heat

such as an external re, observe the following:

The battery’s primary products of combustion are carbon

dioxide (CO2) and water vapor (H2O). Signicantly smal-

ler quantities of carbon dioxide (CO), hydrouoric acid

(HF) and other gaseous intermediate products are relea-

sed as well. Dusts of nickel oxide, cobalt oxide, mangane-

se oxide (with NMC cells) must also be taken into account.
