Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in Morocco that is ONEE Morocco. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Frequently Asked Questions
Is the DEYE SUN-M30G4-EU-Q0-I suitable for the Middle East climate?
Yes. The SUN-M30G4-EU-Q0-I is rated -40 to 65 °C, with derating above 45 °C, which covers the heat and dust of the Gulf, North Africa and the wider MEA region. Mount it in shade for the best summer output. Its IP 67 rating handles dust and humidity.
How many panels can I connect?
Each microinverter supports 1 solar panel (up to 700W), with single MPPT tracker for optimization. Multiple units can be connected per branch (17/13/10 units depending on model).
What is the <100ms AC discharge feature?
This safety feature ensures AC fast discharge in less than 100ms, complying with the new DIN VDE V 0126-95 standard to protect human safety during maintenance or emergencies.
Is the DEYE SUN-M40G4-EU-Q0-I suitable for the Middle East climate?
Yes. The SUN-M40G4-EU-Q0-I is rated -40 to 65 °C, with derating above 45 °C, which covers the heat and dust of the Gulf, North Africa and the wider MEA region. Mount it in shade for the best summer output. Its IP 67 rating handles dust and humidity.
Is the DEYE SUN-M50G4-EU-Q0-I suitable for the Middle East climate?
