What Barnex works with
Barnex works with Deye, Growatt and Victron hybrid inverters, and others are added with a JSON map without new firmware. EV chargers: OCPP 1.6J, ElectroS, Sungrow, Teltonika, Eveus. Up to 10 boilers with a resistive element. Single-phase mains.
Inverters
| Brand | Support | Models | |
|---|---|---|---|
| Deye | Native support | hybrid, SG01HP3 3-phase HV, SG04LP3 3-phase LV | Native support: Modbus TCP and the Solarman V5 logger protocol. Reads PV, load, grid, battery, SOC, voltage and energy counters. On three-phase models, control and breaker protection use one phase only (L1). |
| Growatt | Native support | GEN4 hybrid (TL-XH), SPH-6000 | Native support with automatic identification. |
| Victron | Native support | Cerbo/Venus GX | Native support through Cerbo/Venus GX. |
| Luxpower / EG4 | Via a JSON map | LXP/SNA hybrid (EG4) | Through a JSON register map, Modbus RTU. |
| SRNE | Via a JSON map | HF2430U60-100 | Through a JSON register map, Modbus RTU. |
| SolaX | Planned | — | Can be added with a JSON map; a ready map does not exist yet. |
| Solis | Planned | — | Can be added with a JSON map; a ready map does not exist yet. |
| Fox ESS | Planned | — | Can be added with a JSON map; a ready map does not exist yet. |
EV chargers
| Charger | Support | Connection | |
|---|---|---|---|
| OCPP 1.6J | Native support | OCPP | Any charger with OCPP 1.6J. Version 2.0.1 is not supported. |
| ElectroS | Native support | WebSocket | Locally over WebSocket or through the manufacturer's cloud; read and control. |
| Sungrow Wallbox AC007E / AC011E / AC22E | Native support | Modbus TCP | Control over Modbus TCP. |
| Teltonika TeltoCharge | Native support | Modbus TCP | Control over Modbus TCP. |
| Eveus | Native support | HTTP JSON | Over HTTP JSON; the map is still being verified on real hardware. |
| HTTP-JSON charger from barnex-maps | Via a JSON map | HTTP JSON | Any charger with a published map in the bobyk/barnex-maps repository pairs without new firmware. |
Loads
Boiler with smooth regulation
A resistive heating element through an SSR, a step of about 1%.
Relay-type load
Heat pump, air conditioner, pump: only 0 or 100%.
EV charger
Current from 6 to 32 A, single-phase mains, up to 4 chargers.
What else you may need
- A boiler node if you want to heat a boiler with Lite: Lite has no power output of its own.
- An inverter reachable over Modbus (Deye, Growatt, Victron or another with a JSON map).
- An EV charger from the compatibility list.
It suits you if
- You have single-phase mains
- A hybrid inverter reachable over Modbus: Deye, Growatt, Victron, or any with a JSON map
- From one to ten boilers with a resistive heating element
- An EV charger from the compatibility list (OCPP 1.6J, ElectroS, Sungrow, Teltonika, Eveus)
- You want control that works without the cloud or internet
It does not suit you if
- Three-phase EV charging or three-phase breaker protection: planned, only single-phase mains today
- An inverter without Modbus access: Lite needs it, own CT clamps arrive with DIN and Power
- An inverter that cannot be set to output priority Solar, Grid, Battery: heating stays blocked until the installer confirms
- You need protection against switching on with an empty tank: there is none, only the tank temperature limit
- One boiler on a tight budget: Solar Vampire costs less
Sales start at the end of February. Features are being finalised, so details may be refined.
