Question 1

How does the IQ EV Charger 2 work with the Storm Guard option?

Accepted Answer

The objective of Storm Guard is to prepare the home for any possible outages, by fully charging the home battery and EV before the storm sets in. In case of a storm alert, profile is set to Full Backup and EV charges at 100% from excess solar, followed by grid. Profile change/toggle is deactivated, and the user must toggle Storm Guard off in order to change the profile.

Question 2

How does the IQ EV Charger 2 work with Full Backup Profile?

Accepted Answer

The Full Backup profile will keep the home battery fully charged for possible grid outages. In this profile, IQ EV Charger 2 will charge the EV to 100% using the excess solar energy and will not discharge the home battery.

How do I setup and use an RFID/NFC tag to authenticate charging sessions?

Accepted Answer

Purchase a tag that operates at 13.56 MHz. It needs to be ISO 14443 A/B or ISO 15693. You can even use an existing tag that follows the mentioned protocol and operates at the 13.56 MHz frequency.Register this tag with your IQ EV Charger 2 on the Enphase App. To do this, go to menu -> settings -> IQ EV Charger  -> Authentication. Follow the instructions on the app screen.You can then use the registered tag to authenticate charging sessions.Watch a video on RFID tag registration and usage (to be linked to video)

Question 59

What is Dynamic Load Balancing?

Accepted Answer

Dynamic load balancing - The IQ EV Charger 2 can adjust its charging power based on home consumption, preventing overload on the contracted per phase power/ fuse rating, protecting the home, and avoiding the need for expensive upgrades.The system monitors the overall electricity usage and compares it with the configured contracted power of the home.  If household appliances (e.g., air conditioning, ovens, or heat pumps) are consuming a lot of power, the IQ EV charger 2 automatically reduces its charging rate to prevent overloading the contracted per phase power/fuse rating.  When other appliances use less power, the charger can increase its output, ensuring the EV gets the fastest charge possible while staying within safe power limits.  Whenever the power difference is more than 200W per phase, the IQ EV Charger 2 will respond in under 30 seconds. For any larger power changes greater than 1000W per phase the response will be in less than 20 seconds.To enable dynamic load balancing, the IQ EV Charger 2 and the IQ Gateway or compatible third-party meters such as Linky/P1 needs to be connected to the same network.If you own an IQ EV Charger 2, learn how to enable dynamic load balancing for the site.Know more about Dynamic Load Balancing and the benefits for an installer and homeowner.

Question 60

How can I control access to my IQ EV Charger?

Accepted Answer

You can setup app-based and RFID based authentication with the IQ EV Charger. Go to Menu -> Settings -> Select your IQ EV Charger -> Security Allow App-based authenticationAdditionally, you can add a tag for RFID/NFC based authentication.To do this, go to menu -> settings -> IQ EV Charger  -> Authentication. Follow the instructions on the app screen.

Question 62

My EV is only charging on one phase or at low power. Why?

Accepted Answer

The IQ EV Charger 2 is built to maximise solar usage for EV charging. You can use solar to charge your EV even during cloudy days. See below for how this is possible To enable solar usage even during low light conditions, make sure you enable automatic phase switching. To do this, Menu -> Settings -> EV Charger -> Preferences -> Automatic phase switching

Question 63

My EVSE is supporting 3Phase charging, but why is my EV charging only on 2 phases?

Accepted Answer

The charging behaviour controlled by the OBC(n Board Charger) in the Electric vehicle. Some of the PHEV only support charging in Single Phase or Two Phases.Additionally some EVs though they support Three-Phase charging, they intelligently manage phase usage based on battery temperature, state of charge, or grid conditions. Ex - In cooler climates or during battery conditioning, the car may temporarily reduce phase usage.Hence recommend to check with the EV manufacturer to get clarity on the charging behaviour.Sample Linky adapter:Sample Type A to Type C converter:

Question 64

Why is my EV not charging in Green Charging  mode?

Accepted Answer

I. Please ensure your charging modes are set right. Go to Menu -> Settings -> Profile   Set the profile to Self-Consumption   Pick “Green Charging” as the charging mode   Note that under Green Charging,  EV charges with all the excess solar power available.  Battery is used as a supplement only when the toggle is enabled.Grid power is never used.If an Add-on schedule is set, it overrides the green charging algorithm to charge at the maximum set current, irrespective of the available power source, while still prioritising the available surplus solar.
