New inverters are continuously introduced to the market; unfortunately, we can't get access to test every single one that comes out.
We do have an emulator for the following, which many inverters are trying to be compatible with:
- LG RESU LV Battery CANbus Communication
- Pylon LV Battery CANbus Communication
- Pylon HV Battery CANbus Communication
- BYD HVS Battery CANbus Communication
Have a look at the manufacturer’s inverter datasheet to see if they are compatible with what is listed above or reach out to the manufacturer directly to verify.
We can develop a new CANbus profile to suit your inverter/charger equipment if. Make sure you can provide the protocol document (not the product sales/install datasheet).
However, please be advised that this is a non-trivial requirement and will need developmental effort and it is ideal to have access to their technical departments which can assist with any clarifications.
- For a straightforward interface without complex communication, we allocate 2.5 working days of development and a couple of revisions to resolve testing issues (if there are any).
- For profile development that needs to be fast-tracked (less than 6 weeks) to suit your project timeline and does not slot into our development rollout schedule, this will require an additional 2 working days to prepare a dedicated branch to allow this release.
If you want to request a new protocol, please email us with a request alongside the protocol document required so we can verify if the above estimate would be appropriate.
Below is the list of requirements needed for us to push with the testing. Once accomplished, we can then verify that it works.
- Acquire the manufacturer's protocol document.
- Review the document to determine the complexity and if suitable.
- Implement proof of concept (PoC) firmware.
- Gain access to a test bench/environment with inverter hardware equipment to test PoC.
- Run tests:
a. connectivity - inbound / outbound
b. operational - charge run/limited/off
c. operational - discharge run/stop
d. telemetry to the device (soc, temperature, volt, current, error flags, etc.)
e. remote configurable settings (target max charge volt, max charge current, discharge volt cutout, discharge max current)
- Ideally, have access to technical support from the inverter company which can explain behaviour when it does not match their documentation.
- Merge the proof of concept firmware into the next WatchMon Supervisor firmware release.
- Test supervisor with firmware to confirm works as expected when OK and in fault.
- Retest supervisor for normal operation.
- Release the beta build to the community with new functionality.
