Hi,

Is there a known "ready to use" device available that can connect via 485 into my B3?

I'd rather use a factory made device if I can.

Contacted alpha recently and when I (eventually) got a reply, they confirm Mobus TCP isn't possible.

Thanks.

I’m rocking a B3 too, for what it’s worth. It’s functional but you can sorta tell Alpha have moved on and aren’t taking older kit with them.

A bit like Samsung really.

It’s a shame as I’d have loved the opportunity to build a robust development for modbus tcp.

@dxoverdy do you happen to know the Modbus slave address / ID for your b3 inverter? I have tried 85 and no luck!

Thanks.

dxoverdy commented 8 months ago

The default of 0x55 worked for me and 100% of other folk I know of.

I’d be looking elsewhere for faults to be honest. Regards Dan

@dxoverdy I've got it working. I am however struggling to find the correct registers for the following:

Consumption in watts (total load for the house in watts) - is this the value of the battery + grid + solar combined?

Grid and solar total energy consumed / exported?

Battery load (charging vs discharging)

Any ideas / hints? Thanks.

Those are exposed in the ten second schedule
