The Bosch manufactured Conergy CIS ensures the operators of PV plants maximum return throughout the

life. The central inverters of Conergy comply with all European Legal Norms and standards, such as German

“Medium Voltage Directives “. The entire inverter stations are design approved and comply in dimension and

layout with European Standard Requirements.

Custom tailored final product thanks to flexible combinationIn the station made of weatherproof concrete, the

new generation of Flextech IPG C central inverters

are used. Flextech will offer the complete solution

with a rated output of 1.2 MW. As a result, the

customer is provided with a final product exactly

tailored to meet its needs and requirements – with a

maximum performance and top reliability thanks to

exactly matched system technology.

Preconfigured complete systemThe interconnections of the individual components

have been pre-tested without exception.

Connections, links, the comprehensive protection

system and the certified ventilation and filter

concept are ready for immediate use. Local planning

and installation effort and expense are therefore

reduced to a fraction with the Flextech complete

solution.

Flextech CISs confirm with European directivesLike the new Flextech IPG C central inverters, the

central inverter station also complies with all

currently applicable European standards and

directives for smooth commissioning.

CONERGY CIS 1200

Every solar energy system does not supply power to the grid for approx. 50 % of its service life, for example at night.

In 20 years, this adds up to approx. 88,000 hours.

However, the transformer stations do consume power in this time; the electricity meter turns backwards. The

highly efficient amorphous transformer stations used by Conergy reduce this loss by approx. 60 %.

Flextech VisionBox.The Flextech VisionBox is the

professional system-monitoring

system with extensive functions for

data analysis, fault diagnosis and

automatic alarms.

• Ideal for solar energy systems

from 3 kW up to 18 MW

• Monitors up to 60 Conergy IPG

inverters and/or Conergy

SmartConnect

• Reports faults automatically via

VVthe display and LEDs. You can

also choose to have the alarms sent

via SMS, fax or e-mail

• Offers worldwide access to all

data via PC or Smartphone using

the web portal www.sunreader.de

• Has a standard USB connection

for simple data transfer and

software updates The Conergy

VisionBox app for your iPhone can

now be used to monitor your

system easily while you are on the

move.

Conergy SmartConnect.The Conergy SmartConnect brings

together up to eight module strings,

each with a max. of 20 A, and routes

them securely to the Conergy IPG

C or to Conergy CIS.

The Conergy SmartConnect also

enables accurate and clear

monitoring of strings using a safety

concept that is adapted to PV

technology.

• Simple module string connection

to the inverter with integrated

monitoring

• Transmits the operating data

continuously to the Conergy

VisionBox (accessory

Conergy GridControl.Conergy GridControl is the

interface between the solar power

station and the grid operator. With

this interface, the grid operator can

easily remotely control the output

of photovoltaic systems with more

than 100 kW, as required.

• Processes both analogue and

digital control signals from the grid

operator

• The output interventions made

by the grid operator can be

documented in the logbook of
