Invalid grid
Easee Invalid grid on an EV charger: no valid grid configuration detected
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
The Easee charger cannot detect a valid power grid configuration. Reboot it; if the alert stays, Easee says to double-check the electrical connections, which an electrician must do.
Safety first
Stop and check this first
- If a charger protective device tripped by itself, do not switch it back on repeatedly. Easee says to check the connections; have an electrician do it.
Safe checks you can perform
- Charger reboot
- Position of consumer unit devices
- Supply connection inspection
Leave these tasks to a qualified professional
- Do not attempt this professional task: Voltage between conductors
- Do not attempt this professional task: Connection tightness and earth continuity
What a technician must be able to justify

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Voltage between conductors
What they doThe electrician measures line-neutral, line-line where relevant, neutral-earth and line-earth at the charger terminals.
They must show youreadings for each conductor pair.
In writingvalues and the grid type identified.
Connection tightness and earth continuity
What they doWith the circuit isolated, checks terminal tightness and measures protective conductor continuity.
They must show youany point corrected and the continuity reading.
In writingconnections checked and values against wiring rules.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Charger reboot
- Who:
- you, no tools.
- How:
- reboot the charger as Easee instructs.
- Result that matters:
- whether it recognises the grid at start-up and allows charging.
- If it charges normally:
- it was a one-off; note it.
- If Invalid grid returns:
- rules out a one-off; move to the connections.
- Evidence to keep:
- app screenshot before and after the reboot.
Evidence: Error messages in the app
Position of consumer unit devices
- Who:
- you, looking at the consumer unit only.
- How:
- check that no device on the charger circuit is off or halfway.
- Result that matters:
- all charger protective devices are on.
- If one was off:
- note it and tell the electrician before switching it on if it tripped by itself.
- If all are on:
- the cause is in the connections; call the electrician.
- Evidence to keep:
- photo of the consumer unit devices.
Evidence: Error messages in the app
Supply connection inspection
- Who:
- qualified electrician.
- How:
- with the circuit isolated, inspect connections at the charger and the consumer unit, and measure voltages between phases, neutral and earth.
- Result that matters:
- wiring matches the grid type and is secure.
- If a conductor is loose or wrongly connected:
- confirms the cause.
- If everything is correct:
- review the grid configuration with Easee support.
- Evidence to keep:
- report with readings and photos of the connections.
Inspecting terminals and measuring voltage is electrician work. You do not open the charger.

Where this code applies
A code is meaningful only inside the right product and version context.
Primary scope

Known code variants
- Easee Invalid grid
- Easee invalid grid error
- Easee Invalid Power Grid Detected
- Easee red no válida
What it means
Easee defines Invalid grid as the charger having difficulty detecting a valid power grid configuration. At start-up the charger identifies how it is connected (phases, neutral and earth) to know how to deliver charge. If what it measures does not match a recognised grid type, it blocks. The alert does not say whether the cause is a connection, a missing phase or the grid type.
Warnings and stop conditions
- Mediumeditorial warning
If a charger protective device tripped by itself, do not switch it back on repeatedly. Easee says to check the connections; have an electrician do it.
Evidence: Error messages in the app
Symptoms and causes
Probable causes · in order
- Wrong or loose supply connectionPossible
Easee says to check connections if it persists. If the alert appeared after installing or changing the circuit, this is the first suspect.
Evidence: Error messages in the app
- Phase or circuit protection disconnectedPossible
If a circuit protective device is off or a phase is missing, the charger may not recognise the grid. Checking the consumer unit separates it.
Evidence: Error messages in the app
- Transient condition at start-upPossible
If after a reboot the charger recognises the grid and charges, the alert was a one-off.
Evidence: Error messages in the app
