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 Yemen that is Public Electricity Corporation (PEC), Ministry of Electricity and Energy. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Frequently Asked Questions
Is the Growatt WIT 29.9-50K-XHU 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 WIT 29.9-50K-XHU 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 WIT 29.9-50K-XHU, 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 WIT 29.9-50K-XHU 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.
What batteries does the Growatt WIT 29.9-50K-XHU pair with?
WIT 29.9-50K-XHU is compatible with Growatt's LFP battery range — most commonly the ARK XH, ARK HV, or APX HV stack depending on model and topology. Battery sizing depends on your daily backup load; a typical UAE villa uses 10–20 kWh of usable storage. Contact Growatt MJS Solutions for a tailored sizing recommendation.
What's the lead time for the Growatt WIT 29.9-50K-XHU 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 WIT 29.9-50K-XHU perform in UAE summer rooftop temperatures?
The WIT 29.9-50K-XHU 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.
