Splitvolt EV charger displays E08 and refuses to charge; may occur after a lightning storm or power surge.

Safety first: After a surge event, internal components may be compromised. If you smell burning or see smoke, keep the breaker OFF and do not reuse the charger.

• Verify supply voltage: Have a qualified person measure the line-to-line voltage at the outlet. Ensure it matches the Splitvolt charger's rating (typically 208–240V). If voltage is too high, contact your utility or electrician.
• Power-cycle after surge: Turn the breaker OFF for 5 minutes, then ON. This can reset some surge detection circuits if they have not been permanently damaged.
• Inspect for visible damage: With power OFF and charger unplugged, look for burn marks or melted plastic at the plug or housing. Any visible damage means the unit should be replaced or professionally repaired.
• Use surge protection: For future protection, consider a whole-house surge protector or a panel-mounted surge device installed by an electrician.
• Persistent E08: Indicates likely failure of the input surge protection network or control board. Internal board replacement is required; contact Splitvolt support.
