Overload Protection and Dynamic Load Balancing

Varies the charging output dynamically based on different variables:

• Import from grid – will not allow EV charging plus household load to exceed maximum current set point. Typically 63A single-phase and 50A three-phase in most residential properties.
• Surplus solar production – the EV Wall will vary the load to exactly how much excess solar power there is available maximising self consumption and savings from solar.

Smappee’s Smart Charging Settings

The smart charging feature provides a set and forget solution for EV charging. Allowing users to choose from three different methods of charging their vehicle:

• Surplus only – pretty self explanatory. The EV Wall will charge from excess solar power and nothing else.
• Schedules and surplus – users set how much charge they want to put into their electric vehicle by a certain time. E.g., 100km of charge added on weekdays by 7am. This will prioritise the use of excess solar power during the day and then off-peak rates overnight by tracking solar product and the different electricity tariffs added in the Smappee app. With schedules and surplus enabled, the EV Wall will continue charging past the set point if excess solar is available.
• Schedules only – same as schedules plus surplus. However, this option won’t continue charging if excess solar becomes available. It will stick to the programmed amount of charge that needs to be added each day.
