Charging Modes Explained
Boost
Charges your vehicle immediately at maximum available power.
Use when:
-
You need to charge as quickly as possible
-
You are not concerned about energy costs or schedules
Boost uses all available energy sources to deliver up to 32A, including solar and home battery systems. Surplus energy is prioritised, so export is used first before importing from the grid. This allows users to maximise charging using free renewable energy over grid power.
Eco
Eco maintains a minimum charge rate of 1.4kW, the threshold required to start and sustain charging without interruption.
Use when:
- You have solar panels installed
- You want to prioritise self-generated energy, where self generation is limited i.e. during cloudy conditions where solar generation is l.
Eco prioritises solar and home battery energy. When available self-generation exceeds 1.4kW, the charger will use all surplus energy, up to 7.4kW.
Super-Eco
Super-Eco charges using only solar and home battery energy. No power is drawn from the grid.
Use when:
- You have solar panels installed
- You want to charge using only self-generated energy
A minimum surplus of ~1.4kW is required to start charging. If export does not exceed 1.4kW, charging will not begin.
Mode: Battery-Safe
Battery-Safe builds on Super-Eco by adding protection against battery drain. It monitors system behaviour and pauses charging if the home battery begins to discharge unintentionally.
Use when:
-
You have solar panels and battery storage
-
You want to use surplus solar without draining the battery
A minimum surplus of ~1.9kW, is required to activate charging. If the grid export does not exceed ~1.9kW, charging will not start!

Selecting Charging Modes
Common Misunderstandings
“Charging is slow”
In Eco mode, charging speed depends on available self generated energy. If surplus is at or below 1.4kW, charging will be limited to 1.4kW.
“Charging keeps stopping and starting”
This is expected in Super-Eco mode as the charger responds to changes in available surplus energy. If generation is insufficient, charging will pause and the LEDs will pulse yellow.
