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 Syria that is Ministry of Electricity Syria. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Frequently Asked Questions
Is the Growatt MAX 320K-X approved for use in the UAE?
Yes — Growatt inverters are widely used in DEWA Shams Dubai, SEWA, FEWA, EtihadWE, and SEC Saudi Arabia installations. Verify the MAX 320K-X on the latest DEWA Approved Equipment List before EPC submission. Growatt MJS Solutions can supply DEWA documentation on request.
What warranty comes with the Growatt MAX 320K-X, and is it valid in the Middle East?
5-Year Manufacturer Warranty, valid across every market we serve, including UAE, KSA, Oman, Bahrain, Qatar, Kuwait, Egypt, and the wider Middle East/North Africa. Extended warranty options are available at the time of purchase. All warranty claims are processed locally through Growatt MJS Solutions in Dubai.
How do I monitor the Growatt MAX 320K-X remotely?
All Growatt inverters and batteries integrate with the ShinePhone mobile app and ShineServer cloud platform. Add a ShineWiFi-X dongle or use the built-in WiFi (depending on model) for real-time monitoring, alerts, and multi-site management. The app supports English, Arabic, and 20+ languages.
Can I install the Growatt MAX 320K-X on a three-phase commercial site?
Yes — MAX 320K-X is designed for three-phase 400V grid connections common in UAE/KSA commercial buildings. It supports parallel installation for larger arrays, smart string monitoring, and integrates with EMS/SCADA via RS485/Ethernet. Suitable for warehouses, schools, mosques, and light-industrial rooftops.
What's the lead time for the Growatt MAX 320K-X in Dubai?
In-stock units typically ship within 1–2 business days from our Dubai warehouse. For larger orders or specific configurations, lead times of 2–4 weeks may apply. Contact Growatt MJS Solutions on +971 4 255 0887 or sales@growatinverter.com for an exact quote.
How does the Growatt MAX 320K-X perform in UAE summer rooftop temperatures?
The MAX 320K-X is rated -30 to 60 °C ambient. For UAE rooftops that pass 50 °C in summer, mount it in shade with good airflow and oversize the PV-to-AC ratio slightly to cover afternoon clipping. Its IP66 rating handles dust and humidity.
