Frequently Asked Questions
Is the DEYE SUN-15K-G05 suitable for the Middle East climate?
Yes. DEYE inverters are rated for high ambient temperatures and dusty conditions common across the Gulf, North Africa and the wider MEA region, with IP-rated enclosures for outdoor installation in shaded areas.
What is the Anti-PID function?
The Anti-Potential Induced Degradation (PID) function protects PV modules from performance decline, extending their operational lifespan and maintaining high efficiency over time.
What monitoring options are available?
The inverter supports multiple monitoring options including GPRS, WiFi, Bluetooth, 4G, and LAN connectivity, plus RS485 and RS232 communication interfaces.
What is the MPPT voltage range?
The SUN-18K-G05 series operates with an MPPT voltage range of 200-1000V, providing flexibility in solar panel selection and system design.
Does it support zero export?
Yes! Zero export functionality allows you to manage energy consumption and comply with grid export limits, maximizing self-consumption.
