Model-specific values such as input current, voltage range and number of MPPTs are given in the datasheet; array design is done according to these values. The manufacturer states remote monitoring capability for the series; electrical limit values and certificate documents are collected in the datasheet on the product page.
Which projects is it suitable for?
For vegetable and fruit packing facilities, industrial roofs and mid-sized commercial buildings in Antalya, a 20 kW string inverter both lets you split the investment and ensures that generation does not stop completely in the event of a fault.
Use in Antalya and Solar Nexo support
The Mediterranean climate is advantageous in terms of sunshine duration; according to PVGIS data, 1 kWp of capacity in Antalya theoretically produces about 1,656 kWh per year. Salt and humidity should be considered on the coast, and dust and temperature fluctuations inland. Operating temperature limits and protection class values are given in the datasheet; the mounting point is chosen accordingly.
Solar Nexo manages the process from site survey to commissioning: roof and grid study, panel-inverter matching, installation, monitoring connection and technical support afterwards. You can download and review the technical sheet from the documents on the page and request a quote from Solar Nexo for your project.
