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.
