6 FAQs about [1500v PV string inverter parameters]

Which solar modules are suitable for 1500V PV applications?

SEMIKRON offers complete module portfolio for 1500V PV applications. These modules are ready to be used in string and central inverters. Hence, a wide power range in solar installations is covered. SEMITOP and MiniSKiiP platforms are well suited for small and medium power applications.

Is 1500V a good voltage for solar inverter?

While 1500V is becoming the mainstream for solar inverters (central and string), this new voltage requires careful consideration with respect to creepage and clearance of the power modules and the DC link assembly as well. Also, the new requirement from solar inverter is to operate at near zero power factor.

What is the minimum string size of a PV inverter?

The minimum string size, then, is 15 modules. The maximum string size is the maximum number of PV modules that can be connected in series and maintain a voltage below the maximum allowed input voltage of the inverter. The Module Voc_max is calculated using the coldest temperature when the modules produce the highest expected voltage.

What is the difference between a 1000v and 1500V inverter?

Increasing the system voltage from 1000V to 1500V increases the output voltage of the inverter. While the open circuit voltage is 1500V, extracting full power or Maximum Power Point (MPP) voltage range could vary from system to system and mission profile.

How many DC inputs can a PV inverter use?

If the inverter DC inputs are fully utilized, a maximum current per string of only 13 A is possible. If it is intended to install high power PV modules (500+ Wp) with DC current ratings of >13 A, only one of the two DC inverter inputs can be utilized. Consequently, fewer PV modules can be connected to the inverter.

What is a virtual central PV string inverter?

Virtual Central approach of PV string inverters – a cost benefit Compared to the traditional mounting arrangement where the inverter is fixed decentral at the end of each PV string the so called virtual central offers many benefits.
