Modbus Sunspec Three Phase Inverter not giving values

[GJW]

Hi all,

Can anybody help me out getting Sunspec Three Phase running?

I’m mainly doubting if settings are not correct:
Block Length I tried different values, but cant find what value it should be
Start address 40000 looks fine (with a poller I got some correct data)
Refresh? is it miliseconds or seconds?

UID: modbus:inverter-three-phase:d13e522b99:46dfccd10c
label: Three Phase Inverter
thingTypeUID: modbus:inverter-three-phase
configuration:
length: 50
refresh: 5000
maxTries: 3
address: 40000
bridgeUID: modbus:tcp:SE5000TCP

Many thanks!

maybe this helps a bit
