FAQ Section
Q1: What makes the Deye SUN-(3.6-6.2)K-G04 series ideal for residential roofs?
A: The series features 2 independent MPPT trackers, allowing solar panels to be installed on two different roof faces (e.g., East-West) without cross-string power loss. It provides flexible power ratings from 3.6kW up to 6.2kW on a single-phase 230V connection.
Q2: What is the benefit of the 80V start-up voltage?
A: With a low 80V startup and 70V–500V MPPT range, the inverter turns on earlier in the morning and stays operational later in the evening, capturing significantly more kilowatt-hours during low-irradiance and cloudy days.
Q3: Does this inverter support Zero Export (Anti-Backflow)?
A: Yes. When installed with an external smart meter or CT, the SUN-3.6-6.2K-G04 can automatically modulate solar output to match household consumption, preventing excess power from exporting to the grid where regulations prohibit feed-in.
Q4: Is the inverter noisy during peak operation?
A: No. Thanks to its fanless natural convection cooling design, the inverter operates silently with noise levels ≤35 dB, making it suitable for residential living areas and quiet outdoor settings.
Q5: How can I monitor the inverter's daily performance?
A: The inverter supports plug-and-play communication modules (Wi-Fi, 4G, LAN, Bluetooth). You can monitor real-time generation, historical energy yield, and system health remotely via the Deye Cloud mobile app or web portal.
