I have noticed that the maximum charge rate of our E2 has dropped from previously being ~7kW to now being a maximum of around 6kW. The first time I see this reduction occurring is on 3rd November 2024. The EVSE was reaching 7kW as recently prior to this on 15/10/25.
This time span correlates to our lines company installing new transformers and voltage regulator in our area in late October which has caused issues with our solar’s generation and export levels since due to high grid voltage in our area. Is this issue also responsible for the compromised charging levels we are experiencing?
Could you please send your charger’s serial number to our support team at support@evnex.com so we can investigate your charger’s logs?
The charging current can be affected by other house loads (if it is reaching the max supply allowance).
It will also depend on grid supply voltages. We would need to check how much current your vehicle is requesting and multiple by the supply voltage under load.
Once we had a chance to check your charger’s logs we should be able to see what is happening.
Awaiting your reply but in the meantime a charging session starting at 11:00pm Tuesday night (1st July) and running to 7:00am the following morning was at less than 6kW so combined with the new functionality on the phone app that prevents customising start/finish times we ended up with a less than complete charge into our Polestar2.
We paid the extra $s for what was supposed to be an upgrade from our previous 7kW Juicepoint EVSE in part to use the solar diversion capability of the Evnex but we are now using the Juicepoint EVSE to resolve shortfalls in the Evnex unit’s performance. A prompt resolution of these issues would be appreciated.
Just updating for any readers, there was a fault appearing which was causing the charger to derate prematurely, which was addressed in the new firmware. The charger has been updated and is working at full capacity
