General information

About these instructions

Read these Installation and Operating Instructions thor-

oughly in order to ensure that the MyReserve functions

smoothly. Installation and service must be carried out by

qualied electrician who has been trained and certied

by SOLARWATT. The installation and operating manual

should be easily accessible at all times to everyone in-

volved in work on the storage system.

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 com-

pany is now a leading manufacturer of solar modules – a

provider of intelligent energy solutions for both private

and commercial uses. The MyReserve battery storage sys-

tem completes the systematic approach of SOLARWATT.

By choosing MyReserve, you will benet from a high-qual-

ity and innovative product from the SOLARWATT family.

The product makes use of safe, highly ecient, produc-

tion-ready battery technology combined with excellent

battery module execution. MyReserve also has a battery

management system that eciently operates and moni-

tors all components.

This installation and operating manual enables you to

safely and correctly integrate the MyReserve into a pho-

tovoltaic system so that this innovative battery storage

system can provide the optimal benet and thus increase

your household’s internal solar consumption.

Scope of application

The installation and operating manual applies to the

MyReserve Matrix product family of SOLARWATT GmbH,

which comprises the following product components:

• MyReserve Command 20.2

• MyReserve Pack

• AC Sensor 63

Limitation of liability

SOLARWATT assumes no liability for personal injury, dam-

age to property or the product itself, or for consequential

damages occurring as a result of disregarding this installa-

tion and operating manual. Furthermore, no liability shall

be assumed for damage to the product that results from or

has been caused by improper use, repairs, opening of the

battery storage system, or from any actions of unqualied

persons who have not been certied by SOLARWATT. This

limitation of liability also applies to the use of unapproved

replacement parts and failure to comply with the specied

maintenance intervals. No unauthorized modications or

technical alterations may be made to the product.

Brief description of MyReserve

MyReserve is a DC-coupled and modularly expandable

battery storage system for increased energy supply. The

system is installed between the PV array and the invert-

er and is suitable for existing system and new systems.

MyReserve can feed power into either single-phase or

three-phase inverters. Its AC Sensor detects household

electrical power drawn from or fed into the public grid.

These variables are evaluated in order to determine the

power output of the battery storage or the amount of

charging of the battery. More or less power is transferred

to the inverter depending on household consumption.

The household energy needs are supplied by the PV sys-

tem during the day. If the energy requirement is great-

er than the electricity that is currently being generated,

MyReserve discharges so that the current drawn from

the public grid is minimized. In pure battery operation

(night), the system only discharges the amount of elec-

tricity that the household requires. MyReserve is charged

Page 5

by the surplus electricity of the connected PV system. In

the process, generation calculations of the PV system and

load proles of the household are evaluated by means

of a self-learning, intelligent charge algorithm and an es-

pecially gentle charging strategy is pursued to maximize

the battery service life. The aim of this charging strate-

gy, among other things, is to use the full charge of the

storage battery as late as possible in the day, ending the

process at dusk, which protects the lithium-ion cell and

extends it’s operating life.
