The Irish government provides minimum technical specifications for charging points that Ohme chargers are required to meet. One requirement for single-phase AC chargers, like Ohme chargers, is for the incoming electrical supply to the property to equal 230+\/- 10% volts. This means that the incoming electrical supply to the property (via your local electrical substation) must be between 207 volts to 253 volts for the charger to operate.<\/p>\n\n\n\n

What are Voltage Errors?<\/h2>\n\n\n\n

If the voltage level is higher than 253V or lower than 207V, Ohme will temporarily pause charging, and resume charging once the voltage levels are at a suitable level again. The charger will also show a red flashing \u2018error\u2019 light when these voltage issues are detected to alert you to this – these are recorded as \u2018Over-voltage<\/strong>\u2019 or \u2018Under-voltage<\/strong>\u2019 errors for your Charger.<\/p>\n\n\n

If you have a Home Pro charger, you can check the live voltage reading when the charger is plugged in by tapping the \u2018Next View\u2019 button twice to see this screen.<\/p>\n

If you notice the highlighted number is above 253V, this means the charger has an \u2018Overvoltage\u2019 error, and if it is showing below 207V, this means the charger has an \u2018Undervoltage\u2019 error.<\/p>\n<\/div>\n

How to solve Voltage issues<\/h2>\n\n\n\n

If you believe your voltage levels may be too high, or too low, and this is affecting your charging, the ESB will be able to test the voltage levels at your home and help to adjust the voltage to the correct level. You can begin this process here – Voltage Issues & Quality of Supply<\/a><\/p>\n\n\n\n

To ensure accurate testing, it is important for the ESB to monitor the voltages over the course of a few days, as a single reading may not pick up the issue. This is because the voltage levels fluctuate throughout the day and night. During this monitoring period, we recommend to continue using the charger as usual during this monitoring period.<\/p>\n\n\n\n

Once the high or low voltage level has been confirmed, the ESB will help resolve the issue at your local substation.<\/p>\n\n\n\n

Should you continue to experience any voltage issues after the ESB has confirmed the local levels have been adjusted, please contact our Customer Care team below to confirm this with any supporting reports from the ESB, and we can help action the next steps to get you charging again.<\/p>\n\r\n\t\t\t
