EV charging
Wallbox vs portable EV charger for a South African home?
A fixed AC wallbox with a CoC and load management is the durable home answer for regular overnight charging; a portable Mode 2 / Mode 3 lead is a travel and temporary tool, not a substitute for a compliant dedicated circuit. Choose based on weekly kWh, DB capacity, estate rules and whether you need the point during load shedding.
Updated 27 October 2026 · Illustrative ranges — not a formal quote, credit decision or legal advice.
Answer first: If you charge at home most nights, budget a dedicated AC point (often ~3.6–7.4 kW single-phase, sometimes three-phase) installed by a registered person with a CoC. Keep a portable lead in the boot for visits and emergencies — charger cost · charger overview · wiring / CoC · DIY limits.
Comparison table
| Factor | Fixed wallbox | Portable lead |
|---|---|---|
| Compliance story | Dedicated circuit + CoC | Often shared plugs; riskier long-term |
| Charge rate | Usually higher, adjustable | Often limited by lead / socket |
| Load management | Common with smart wallboxes | Rare / manual |
| Estate / insurance | Easier to declare | Harder to defend after an incident |
| Travel use | Stays home | Wins for road trips |
Load shedding and solar pairing
A wallbox on the non-backup board simply stops during Stage unless you planned otherwise. Solar self-use daytime charging often beats evening grid rates — schedule accordingly — EV from solar · load management · charge cost · EV guide.
Connectors in SA
Type 2 AC dominates home wallboxes; CCS2 is the common DC public standard. Confirm your vehicle inlet before buying adapters as a lifestyle — connectors · apartments · estates.
When portable is enough
- Low weekly kilometres and a robust outdoor socket already on a correct breaker (still have an electrician confirm).
- Rentals where the landlord forbids a fixed point — get that refusal in writing — landlord / tenant.
- Second vehicle / guest occasional use alongside a primary wallbox.
Commissioning habits
- Measure voltage drop and breaker loading with a clamp meter at full charge rate.
- Label the circuit; photograph the CoC page.
- Set a solar or TOU schedule in the app on day one.
- Test behaviour at Stage start if the point is on essentials (usually it should not be unless sized).

Worked weekly kWh maths
A 40 kWh usable EV battery topped from 30% to 80% three times a week is about 60 kWh/week. At home on a 7.2 kW wallbox that is under nine hours of charge time, easy to park on daytime solar or off-peak TOU. The same energy on a weak portable lead stretches into overnight grid peak more often — charge cost · Cape Town TOU · EV from solar.
Public DC vs home AC
Public CCS2 stops (GridCars, Chargify hotel sites attributed to the City Lodge >120 PR, SAEV Charge Richmond snapshots among peers) are for travel. Home AC should cover the weekly baseline. Do not size a hybrid solely to avoid every public session — EV guide · Chargify / City Lodge notes · SAEV Richmond snapshot.

Single-phase load budget sketch
Main breaker 60–80 A, geyser 3 kW, oven 3 kW, wallbox 7.2 kW — coincidence trips are predictable. Load management that throttles the EV when the stove draws is usually cheaper than a rushed three-phase upgrade — load management · three-phase EV · NMD / phase cost · NMD explained.
Guest and Airbnb use

Apartment and estate constraints
Basement bays, visitor bays and HOA rules can block a wallbox even when the DB has capacity. Get written consent before ordering hardware; portable leads on shared circuits remain a last resort with electrician sign-off — apartments · estates · sectional title.
Solar-first scheduling
Set the wallbox to daylight or surplus modes when the hybrid app allows it. Evening peak charging on TOU tariffs can erase the home-charging win — Cape Town TOU · Homeflex · monitoring.
CoC and handover photos

Portable as travel kit, wallbox as home infrastructure
A Mode 2 portable on a domestic socket is a temporary bridge: slow, thermally stressed plugs, and usually no load management with your hybrid. A fixed wallbox on a dedicated circuit with CoC, correct RCD type and optional solar/TOU scheduling is the home pattern — home charger cost · wiring / CoC · DIY risks · EV from solar.
Load shedding and hybrid interaction
Wallboxes that ignore SoC and Stage will flatten the pack. Prefer chargers that pause on backup or respect a household load limit — SAEV Charge and peer wallboxes with scheduling among GridCars / public DC networks for travel days — load management · TOU / prepaid · EV guide.
Insurance and estate rules

Quick questions
Is charging from a kitchen plug OK?
Not as a long-term plan — shared circuits, heat and earth-leakage trips are common failure modes.
Will a wallbox work during load shedding?
Only if it is on a backup board that was sized for it — most homes keep EV charging off essentials.
Do I need three-phase?
Only if coincidence peaks and charge-rate targets demand it — try load management first.
