3 Frequently Asked Questions about “High Altitude solar inverter Selection - BlackVolt Energy Storage”

What happens if a central inverter reaches a high altitude?

The maximum permissible DC voltage of the central inverter decreases. The maximum AC power of the central inverter decreases. In altitudes above 2,000 m MSL, special ambient conditions occur which have an impact on the operation of the central inverter. For these altitudes, there are special order options for the central inverter.

How to choose a central inverter?

For these altitudes, there are special order options for the central inverter. You must also take into account the impact of the air density on the DC voltage and on the AC power of the central inverter when selecting the device type. With increasing altitude, the air density reduces and thus the electric insulation effect of the air.

How does altitude affect electrical insulation?

With increasing altitude, the air density reduces and thus the electric insulation effect of the air. Due to the reduced electric insulation effect of the air, creepage or partial discharge may result. In order to prevent such electrical discharges, the DC voltage must be reduced.

High Altitude Photovoltaic Inverter Selection

To handle high/medium voltage and/or power solar PV system MLIswould be the best choice. Two-stage inverters or single-stage inverters with medium power handling capability are best suited for string

Does Altitude or IP Enclosure Rating Affect Inverter Derating?

This self-preservation mechanism is known as derating. While many system owners are aware of thermal derating due to high ambient temperatures, two other critical environmental factors

Heat, Altitude, and Derating: Sizing Inverters for Reality

Real sites face summer heat, thin air at high elevations, dust, and tight enclosures. Inverter derating under these conditions can trim available AC power and reduce efficiency. This

Precautions for the use of inverters
