Energy Manager FAQ
Our Wired and Wireless Energy Managers are monitoring devices which enable load balancing and solar charging. If you don’t have solar panels then the EM still provides load balancing.
The Wired EM is compatible with both the Home Basic and Home Plus EV chargers, while the Wireless Energy Manager is compatible with the Home Plus EV charger.
The Wired EM is a wired connection from the consumer/fuse board to the charger, it can be a good option when the charger is installed quite close to the consumer board.
The Wireless EM uses LoRa (Radio) technology to communicate with the charger. The Wireless EM has 2 modes –
1. In Standard Mode the Wireless EM has a range of up to approximately 65m.
2. The range in Long Range Mode is up to approximately 80m.
Long Range mode is only supported when using an external USB-C power supply.
Load balancing is a safety feature which automatically balances the power consumption between your house and your electric vehicle charger, to avoid overloading your fuse. For example, if your home has a 60A fuse, and you turn on the electric ovens, electric showers and other high draw appliances and try and charge your vehicle same time, there may not be enough load available for the charger to charge at the maximum rate (which is 32A). When this happens, the electric charger automatically lowers the charge rate to avoid overloading your supply. This is commonly referred to as dynamic load balancing.
You will need to purchase a Simpson & Partners Energy Manager (EM) to enable load balancing.
There are three different solar charging modes:
• Eco: Only charges if there is solar surplus above the minimum threshold of 1.4kW, if not it stops charging
• Eco Max: Pulls from the grid if the surplus falls below the minimum threshold, to bump it up to just above the threshold to continue charging
• Max: Uses a combination of solar surplus and grid energy to charge at the maximum possible rate
Simply select your solar mode from the app schedules page.
So, for example, you could set up two schedules –
1. Use Eco during the day to only charge with solar (if there is sufficient surplus).
2. If you still need to charge the car, select a grid off peak time for the second schedule.
