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 Sudan that is Sudanese Electricity Distribution Company (SEDC), Ministry of Energy and Petroleum. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
