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 Netherlands that is ACM Netherlands. 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.
