elimination of high voltages
SolteQ makes your PV-System safe!Every PV-System must have a safety power down system.
For the easy and quick retrofi t of a existing system, but also for new systems, we realized a new and low cost system for power down the PV-System.Only one SolteQ-Stingbox is needed for each string. Connect the Stringbox with the solar string and with the inverter, that‘s all !
The SolteQ-Stringbox
The Stringbox system can be switched in the simplest case by the AC-Fuse. It is highly recommended to use a emergency button, to safe valueable seconds in case of fi re.A high level system can use a HMZ, which functions as emergency button, but also as central station same time, without additionalexternal controllers. The HMZ owns several in- and outputs to connect for example smoke sensors, external fi re alarm system or even further slave emergency buttons.Please ask for further informations for the producht brochure.
Emergency button and central station (HMZ) or only emergency button (HMDK)

SAFETY AND FIRE PREVENTION SYSTEM
CLEAN AND SAFE ENERGY
The new SolteQ-Stringbox - quick and easy !Easy to install: Connecting the string cables to the Stringbox and the Box with the inverter - that‘s all !Alternative to the popular SolteQ-BFA-System, which works on module level, the new Stringbox can be used for retrofi t or also for new systems. The Stringbox works on string level and makes a shortcut to the string if the button will be pressed.
Power down the PV-System by pressing theemergency button or switching off the AC-Switch
or
automatically by smokesensoror other sensors
Power on again easy by turning the key
... without any damages on the modules
... for new installations and for retrofi t.
up to
20 years*
*waranty upgrade for the elec-tronic components possible
Safe and autarkic power down of the System !Each string gets his own Stringbox. The string is beiing short-circuited by a real mechanical safety contact, so there are absolutelyZERO VOLT in the system, on the roof and on all cables.Even on a loss of the supply cable of the stringboxes, for example by fi re or cutting via axe or switching of the supply of the building, the safe power down process is guaranteed by internal stored energy.In every possible case the power down will be done.
Fail-Safe-Function + full automatic power down within 50mS !!
14 ways for safe power down
The Solarmodules will be switched off one by one if 1. the grid energy supply of the building is switched off 2. the fuse is switched off 3. the datacable of the BFA-System is damaged by fi re 4. or is cuttet by knife 5. the master or slave emergency button is pushed 6. a alarm signal from a fi re central or smoke sensor is setted 7. the datacable will be cuttet from the roof 8. the modules fall down from the roof 9. one of the system components fail (fail safe) 10. the water sensor gives an alarm 11. the arc detector gives an alarm 12. remote controled by SMS or handy app 13. by the inverter, if it gives an alarm 14. over a temerature sensor on the inverter ... and keeping switched off up to turning the key again !Easy power down, also for maintenance and service works - Single string power down
Even service and maintenance works can be done with zero dangerous of high voltages. A single string or even the complete solarsy-stem can be power downed easily only by pressing the button. The works can be done and after that the system can be start up againeasily by turning the key.
Automatic power up after grid supply loss
A short loss of the grid voltage up to 2 seconds will have no effect. If the grid supply fails longer period and comes back, the BFA-System starts up the system automatically again.
Automatic power down in case of fl ood
The fl ooding sensor is for territories which are endangered by fl oodings. The sensor detects the water and sends a signal to the cen-tral station which switches the modules off. DC-Arcs will be killed automatically this way.
Integrated string diodes
Every stringbox includes a string diode. This makes it possible to connect some strings parallel without infl uence to each other. In case of a system power down by the stringboxes there will be no short cut to the inverter.
Every PV-System should
have an emergency button !

SAFETY AND FIRE PREVENTION SYSTEM
COMPONENTS & VARIANTS
1. The emergency button & basic station HMDK
With a emergency button the system can be power downed from the entrance of the building. Important seconds can be safed this way.
Contact load: max. 50 StringboxesWith Switch-Relay: No Limit
2. The emergency button as central station HMZ
The emergency central button HMZ is in same time the basic station of the BFA-system. This includes all inputs and outputs.
Inputs: • external alarm input for fi re station or smoke sensor • Additional emergency buttons (Slave)Outputs: • potential free contact
The potential free contact can be used for the display, gate control or other things.

3. The Stringbox for new systems or for retrofi t
Each string gets it‘s own stringbox. This way guarantees that each string will be short cutted independently of the solarsystem.The count of boxes is not limited.

SAFETY AND FIRE PREVENTION SYSTEM
COMPONENTS & VARIANTS
Connect diagramm
The connection is very easy: All Stringboxes will be connect in row or parallel to the data cable, independing of the solarsystem. A Central Station HMZ can handle up to 50 Stringboxes directly. If more boxes are used only a switch relay is needed, and the totalcount of boxes is not limited.To a Central Station HMZ slave buttons can be adapted, for example on several entrances of a building.Anschlussbild des BFA-Systems:

CONNECTION & INSTALLATION
Inverter neutral !
Results no short cut at the inverter by
integrated string diodes.
Works independent from
the solar system !
Each String gets a Stringbox. The Stringboxes are connected via data cable.The power down process will be started via a central button HMZ.The power down will be done by short cutting of each string cable by it‘s Stringbox.

SAFETY AND FIRE PREVENTION SYSTEM
ACCESSOIRES
Smoke sensor If a building has no fi re alarm system it can be used simply a smoke sensor for fi re detection and power down the solar system automatically. Re-commended: one smoke sensor in every room, fl oor, stairway etc.
Slave emergency buttonEmergency buttons should be installed on every entrance of the building.There can be connected unlimited counts of buttons as needed.Available in several colours and customized inlay it wanted. Dimensions: 133x133x36mm
GSM/SMS-ModuleBy using a SMS module in case of fi re a message can be send to one or more telephone numbers.
Illuminated display „Solarsystem power down“With the display the status power down can be shown, so the fi remen can see direktly from distance „everything is OK, we can work!By a integrated battery the illumination can work power failure proof even if there is no more power from grid available.The Display is readable also from distances up to 50m.
Technical dataDimensions: 42,5 x 22,5 x 6,5 cmProtection class: IP54Power supply: 230V/ 50/60Hz (24/100/110V/ 50/60Hz) Power failure proof“
Telephone dialer In case of Alarm a alarm mes-sage will be send to a telephone number.
FlashlightsThe xenon fl ashlights can be mounted everywhere inside and outside, where the fi reman can see it well.The robust plastic casing (IP34) protects from envi-ronmental infl uences. Operates only with Display.
Available in colours: red, yellow, bluePower supply: 12V via display
Flooding sensorThe new fl ooding sensor detects a fl ooding and triggers the central station to switch the system off.For connection to the central sation (Master-Emergency-Button)
Arc detektor Every arc will be detected safe at his beginning and give the signal to power down the system. So the arc will be killed and a fi re will be possibly avoided.
