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 DEYE BOS-W suitable for hot climates like the Gulf?
Yes. The BOS-W uses LiFePO4 chemistry with a BMS and thermal management designed to operate safely in the high ambient temperatures common across the Middle East and Africa.
What inverters is the BOS-W compatible with?
The BOS-W is designed to work with Deye SUN-50K-SG01HP-EU-BM4 and SUN-80K-SG02HP3-EU-EM6 inverters for complete C&I energy storage solutions.
How long can the battery sit without charging?
Thanks to low self-discharge, the BOS-W can sit for up to 6 months without charging while maintaining safe operation.
