Soluzione Solare at Intersolar 2025: Where Italian tech meets the PV global market

Details

The ENV 4 is an economy ambient temperature sensor  designed for Sunmeters where particular measurement accuracy is not required. With a single device, you can monitor three critical parameters ; irradiance, module temperature and ambient temperature through the Sunmeter, without adding extra hardware to your PV monitoring system.

This ambient temperature sensor for PV modules features a sensor design that allows simultaneous readings from two locations (for example, the module backsheet and the surrounding air), improving the depth and accuracy of your PV system analysis. The analog output ensures full compatibility and easy integration with the Sunmeter platform, while the rugged, UV-resistant housing guarantees reliable operation in all weather conditions.

Designed specifically for outdoor use, the ENV 4 offers fast response times, good thermal sensitivity and plug-and-play connectivity, making it a compact and durable ambient temperature sensor for professional PV applications.
