Vehicle limit
The onboard AC charger caps useful power even when the EVSE can provide more.
Australia · evidence-based compatibility
Start with the EV and energy system you already own.
A 22 kW wallbox is not a 22 kW charging result. BecSpec separates vehicle onboard charging, home phase/supply, existing solar inverter, stationary battery, solar optimisation, load management and smart charging so one feature never masquerades as another.
What this resolver keeps separate
Site limit
Single-/three-phase supply and the installed circuit determine what the EVSE can actually offer.
Solar & battery functions
These require explicit ecosystem relationships, meters/controllers and sometimes firmware or operating-mode prerequisites. The inverter and battery you select are used to reject unsupported ecosystem assumptions.
Evidence-fit ranking
Leave the charger blank to compare the bounded charger cohort. Ranking uses the functions you request and your selected system context first; useful AC rate is only a secondary tiebreaker. There are no review, price or affiliate scores.
V2X
V2H/V2G stays unavailable or unknown unless vehicle capability, charger interoperability and the Australian market pathway are separately evidenced. Historical CHAdeMO trials do not automatically establish a current installation route.
Australian EV charging guides
These guides answer the common questions that sit behind the compatibility checker without collapsing them into one generic charger recommendation.
3 phase EV charging: 7 kW vs 11 kW vs 22 kW
Why a 22 kW wallbox does not guarantee 22 kW charging, and how the vehicle onboard charger changes the result.
Solar EV charging and inverter compatibility
How PV-surplus charging, meters, inverter ecosystems, stationary batteries and tariff control fit together.
