Gridly
Overview
ZJ Beny doesn’t have brand recognition in Australia. What it has is a $700 open OCPP EV charger - and in a market where OCPP typically costs $1,300+, that’s a specification gap worth examining.
The unit delivers OCPP 1.6 open integration, IP65 outdoor rating, and a 5m tethered Type 2 cable. What it doesn’t deliver is load management, Australian warranty support, or the reassurance of a brand with established Australian service infrastructure. Whether that trade-off is acceptable depends entirely on the buyer.
Open OCPP at $700
The ZJ Beny 7kW is the cheapest open OCPP home EV charger available in Australia. For context:
| Charger | Price | OCPP type | Load management |
|---|---|---|---|
| ZJ Beny 7kW | $700 | Open 1.6 | No |
| Evnex E2 Flex | $799 | Closed (Evnex only) | Yes |
| Wallbox Pulsar Plus 7kW | $1,345 | Open 1.6 | Yes |
| Evnex E2 Core | $999 | Closed (Evnex only) | Yes |
For a technically capable buyer running Home Assistant who wants to integrate charger management into a home automation system, the ZJ Beny provides the key capability at the lowest available price. The Wallbox Pulsar Plus at $1,345 is the alternative that adds load management and Australian brand support - for $645 more.
What open OCPP enables on the ZJ Beny
With the OCPP endpoint configured to a compatible backend:
- Home Assistant: The OCPP integration (available in Home Assistant) can start, stop, monitor energy consumption, and set charge schedules. For HA users managing solar, battery storage, and EV charging in automation flows, this is the entry point.
- Off-peak scheduling: OCPP-based schedule management for time-of-use tariff optimisation - charge between 11pm and 6am at off-peak rates.
- Energy monitoring: Per-session kWh data accessible via OCPP, useful for tax reporting on work-related EV use.
No load management
The ZJ Beny has no CT clamp and no load management capability. For homes with limited main supply (older 40A or 60A boards) or heavy concurrent electrical loads, this creates switchboard overload risk.
Workarounds:
- Set the charger’s maximum current to a lower value (e.g., 20A instead of 32A) - reduces maximum charge speed but prevents overload
- Use the vehicle’s own scheduling to avoid charging during peak household load periods
- Install a separate standalone load management device upstream
For homes with 63A or larger main supply and no unusual concurrent loads, the absence of load management is not a practical constraint. For older homes, it is.
Support and warranty: the honest picture
The 2-year warranty is processed through ZJ Beny’s Chinese distribution network. In practice:
- Warranty claims may require shipping the faulty unit internationally
- Replacement parts are not stocked by Australian distributors
- Phone or email support operates on Chinese business hours
This is the primary reason the ZJ Beny is appropriate for technically capable buyers and not for buyers who want seamless warranty support. An installer familiar with the product can sometimes facilitate replacements faster, but there is no established AU service network.
If support and warranty confidence are priorities, the Evnex E2 Core at $999 (4yr warranty, Australian support) or the Wallbox Pulsar Plus at $1,345 (open OCPP, load management, Australian distributor) are better choices.
Who should buy the ZJ Beny 7kW
Best for:
- Technically capable buyers who specifically need open OCPP for Home Assistant or energy management at the lowest possible cost
- Buyers comfortable with the China-based warranty process
- Properties with adequate main supply where load management isn’t needed
- Price-constrained buyers who want OCPP over load management
Skip if:
- Australian warranty support is important - choose Evnex, Wallbox, or Schneider
- Load management is needed - the ZJ Beny has none; choose Wallbox Pulsar Plus or Evnex
- Brand confidence and installer familiarity matter - less known than Evnex or Wallbox in AU installer circles
