SMA Solar Technology AG The Sunny Backup System S

2 The Sunny Backup System S

2.1 Properties

The Sunny Backup System S consists of one Sunny Backup 2200 in combination with one Automatic Switch Box S (AS-Box-S.1), one external Sunny Remote Control 1 (SRC-1) display and one external BatFuse A.01 DC fuse. This system is specially designed for backup applications and enables, in compliance with all standard requirements, continued operation of a grid-connected PV system in the event of grid failure. Thus, this system does not replace the conventional Sunny Boy (PV inverter), but is installed additionally. In the event of grid failure, the Sunny Backup System S first ensures safe disconnection of the loads and the PV system from the public grid, and subsequently forms a stable stand-alone grid, into which the Sunny Boy can then feed solar energy. The maximum period of interruption for the loads is approximately 50 ms, which for most loads is equivalent to uninterrupted operation.

The Sunny Backup System S is suitable for use in conjunction with the Sunny Boy PV inverters from SMA Solar Technology AG. The Sunny Backup System S can be integrated into new PV system installations, and can also be retrofitted onto existing PV systems.

Along with the Sunny Backup 2200 and the automatic switching device AS-Box-S.1, a battery is necessary as a short-term storage device, for reliable operation. During grid failure, the battery has the task of correcting the imbalance between generation and consumption. Whenever less energy is being generated than consumed (e.g. at night), the battery is discharged. Whenever more energy is being generated than consumed (e.g. during the day), the battery is charged.

Technical Description SBU2200-TEN083320 11

The Sunny Backup System S SMA Solar Technology AG

The intelligent battery management built into the Sunny Backup 2200 protects the battery from overcharging and deep discharge. This ensures that the battery service life stipulated by the battery manufacturer can be achieved.

As an external DC fuse, the BatFuse A.01 protects the battery connections of the Sunny Backup 2200. Additionally, the BatFuse A.01 enables the DC-side disconnection of the Sunny Backup 2200.

The Sunny Backup 2200 performs the entire controlling and regulation of the system. If the system is in grid-parallel operation, the Sunny Backup 2200 ensures standard-compliant grid monitoring and battery-preserving charging. The Sunny Backup 2200 is extremely quick to detect any failure of the public grid and disconnects the system from the grid. After approx. 50 ms, the loads will be already supplied with electricity again, from the battery. After a matter of seconds, the PV system switches to this stand-alone grid, and either powers the loads, or is used for recharging the batteries. The efficiency during charging, regardless of whether from the grid, or from the PV system, and during discharging, is up to 93 %. Due to the 's very high overload capability of up to 3.8 kW for 5 minutes, and the integrated smooth startup of the Sunny Backup 2200, critical loads with very high start currents can also be started safely. Thus, over-dimensioning of the Sunny Backup 2200 is not necessary.

Requirement according to VDE 0126-1-1 and guidelines of other countries

The Sunny Backup System S meets all requirements of the VDE 0126-1-1 guidelines that are required in Germany for feeding PV electricity into the grid as well as guidelines of other countries. The switching devices for PV feeding are implemented redundantly, and are monitored. The safety of this system has been inspected and certified by the German Professional Association for Precision Engineering and Electrotechnology.

Information

The Sunny Backup System S is only intended for use in TN systems!

Despite the complex functions of the Sunny Backup system, it can be installed and configured with ease. All special material required for installation is included in th e de liv ery . Additi ona l su b-d ist rib uti on units are generally not necessary. The safety and fuse protection concept on the consumer side, and that of the PV system, are generally not impaired by the Sunny Backup 2200, and do not need to be adapted.

All the settings required for operation can be quickly and easily programmed in six steps using the "Quick Configuration Guide" of the Sunny Backup 2200. The easy-to-understand menu navigation allows quick access to all important data, even while the system is running. An MMC/SD card provides uncomplicated system control, and thus makes any service work easier.

Information

Observe the battery manufacturer's installation instructions, as provided with the battery upon delivery, and the applicable standards and directives for installation of batteries (EN 50272-2).

DANGER!

Danger to life due to fire.

• Smoking prohibited!

Do not allow open flames, embers, or sparks near the battery!

DANGER!

Danger to life due to short circuit.

Metal components of batteries are always energized.

• Do not place foreign objects or tools on the battery!

• Only perform work on the battery using insulated tools!

DANGER!

Danger to life due to leaking electrolyte.

IDuring normal operation, it is not possible to accidentally touch the electrolyte.

• Do NOT irreparably damage the battery housing!

• Immediately replace a battery with defective housing!

Batteries must be accommodated in protected rooms, and sufficient ventilation of the installation location must be ensured. Due to the safety extra-low voltage, battery systems that are only connected to one Sunny Backup 2200 do not require protection against direct and indirect contact.

It is not necessary to install such batteries in a separate battery room, or in a self-contained electrical facility.

40 SBU2200-TEN083320 Technical Description

SMA Solar Technology AG Mounting

The necessary air volume flow for ventilation of the room which accommodates the batteries is calculated as per EN 50272-2 under the following assumptions:

• Nominal battery voltage = 24 V

• Battery type: closed lead acid batteries (VRLA)

• Max. charging voltage = 2.4 V/cell

as follows:

Q = 0.0048 x C

with C

as the 10 hour nominal capacity in [Ah].

[m³/h]

The cross-sectional area of the ventilation inlets and outlets is calculated according to the following formula:

A = 28 x Q [cm

]

In the area near the battery, it is not always ensured that the explosive gases are sufficiently diluted. For this reason, a clearance distance is to be observed in which no equipment which causes sparks or smoldering is permitted.

The clearance distance is calculated as follows:

d = 5.76 x (C10)

1/3

FLA battery

Fo r cl osed lea d ac id b att eri es with t he s ame chargin g vo lta ges , th e ve nti lat ion require men ts are higher. The requirements exceed the specifications listed here by a factor of 5. As closed lead acid batteries are generally charged with even higher charging voltages, the ventilation requirements increase even further.

The batteries can either be installed directly on the ground, or on a special battery mount.

Installing a battery with liquid electrolyte

With closed batteries, installation in an acid-resistant collecting tray is to be provided for so that, in the event of a fault, leaking electrolyte cannot cause further damage.

Finally, install the battery bank in accordance with the installation instructions provided by the battery manufacturer.

7.2 DC Connection

WARNING!

The Sunny Backup 2200 does not have an internal DC fuse.

• Install an external DC fuse with 125 A between the Sunny Backup 2200 and the battery.

7.2.1 Grounding

External grounding

The external grounding of the battery's negative pole is normally possible since the batteries and the grid side are galvanically isolated from one another in the Sunny Backup

2200. In this case, make sure that the high currents that may occur under fault conditions can be adequately discharged.

If a ground connection is necessary, it must be established separately by an installer outside of the Sunny Backup 2200.

Calculating the Protective Earth Conductor Cross-section

SMA Solar Technology AG cannot calculate generally valid values for the required cross-section of the grounding cable for external grounding of the battery. The conductor dimensions depend on the type and size of the battery connected, the external fuse (DC side) and the material used for the grounding conductor.

Determining the cross-section

Exact calculation of the protective earth conductor cross-section must take account of the regionally applicable standards and guidelines (e.g DIN VDE 0100 Part 540).

The required cross-section of a (copper) protective earth conductor can be calculated using the following formula. Trigger times of about 25 ms are typical for short-circuit currents between 2000 A and 10000 A.

t = Short-circuit duration in seconds

= Maximum battery current (short-circuit current) in amperes

S = Cable cross-section in square millimeters

A grounding conductor of 16 mm² cross-section is thus adequate for short-circuit currents up to 10000 A.

8.2.1 PV Feed-In Counter (X1/PV Meter)

Connect the X1/PV Meter connection to the feed-in counter for the PV system.

The cross-section of the cables depends on the upstream fuse. Use a conductor crosssection of max. 6 mm². The terminals are designed as spring-type terminals. The nominal AC current is 20 A.

The protective earth conductor (PE) is inserted into the PE terminal of the X1/PV Meter in order to connect the Automatic Switch Box S to the equipotential bonding bar of the building.

To feed in and connect the AC cables, proceed as follows:

1. Select a suitable cable opening on the bottom of the housing.

2. Strip away the outer sheath of the cable to the point where it matches the cable length to be installed in the device.

3. Use a pin-shaped object to prick a hole in the rubber membrane at the feedthrough position.

Do not use a knife or cutting pliers for this.

4. Thread the prepared cable through the small hole you just made in the elastic membrane.

The membrane must tightly reseal around the cable sheath.

5. Establish a suitable level of strain relief for the cable outside of the Automatic Switch Box S.

6. Route the wires to the connection terminals.

The dimensioning of the output cable is to be selected according to the routing conditions, the PV power output and the upstream fuse on the grid side (see also X1/PV Meter connection).

With regard to short-circuit protection, the Sunny Boys and Sunny Backup 2200 devices do not need to be taken into account as, due to their design, they cannot endanger the cables if a short circuit occurs. In the event of a short circuit, only short-circuit currents from the grid require fuse protection. Overload protection is always guaranteed if, as can be assumed, the cables which you route to the PV system are designed for at least the feed-in power of the PV system.

NOTICE!

Device fault due to incorrect connection of other feed-in generators.

DANGER!

Risk of death from feedback into the public grid.

If three-phase loads are connected in the backup system, feedback into the public grid via one of the L conductors may occur in the event of a grid failure.

• Only run single-phase loads in a Sunny Backup System S.

DANGER!

Risk of death from leakage currents.

Install a RCD switch between the Automatic Switch Box S and the loads.

NOTICE!

Device fault due to overcurrents.
