SINACON PV Inverter

Better Derating

Made for harsh environments:

Most utility scale projects are in “solar belts”

Dessert areas with extreme temperatures

Tropical climates with highest humidity

Installations close the coastHigher Energy Output:

Later derating at higher

ambient temperature

More energy harvest at

higher altitude

Effective also with high

ambient humidity

SINCAON PV Inverter

Designed for harsh environments

The SINACON PV inverter is used in medium and large PV plants. In order to achieve high

profits, the SINACON PV inverter is equipped with 3-level IGBT modules for input

voltages of up to DC 1500 V and thus optimized for high efficiency.

The integrated DC and AC distribution makes the SINACON PV inverter cost efficient.

Standardized interface for easy plug and play reduce engineering hours.

Unique Selling Points:

Designed for harsh environments

IP 65

Maintenance free liquid cooling

Late derating

Extreme high quality according to Siemens standards

Grid Management of SINACON PV Inverters

The requirements of the grid security management can be met by parametrization of the

functions in the SINACON PV Inverter by :

- Remote Access via VNC

- Modbus TCP Interface

- Powerlink Interface

Connection Conditions can be set:

Static Grid Support available

Dynamic Grid Support available

Shutdown behaviour can be configured for voltage/ frequency dips / rises

Grid Voltage/ Frequency Monitoring available

Connection Conditions

Connection Conditions can be set (Eg):

> If Grid Voltage above UC0390 or below UC0400, grid disconnected

> If Grid Frequency above UC0410 or below UC0420, grid disconnected

We have to leverage our collective

intelligence and curiosity!

Socrates:

“The secret of change is

to focus all of your energy,

not on fighting the old,

but on building the new”

Socrates (470 – 399 BC) was a Greek philosopher
