Daisy-chain AC battery inverters for comms?

#1

Post by ivan »

I now have 2 x ME3000SP AC-coupled battery inverters running in parallel - supplying electricity to my house when there's no PV power.

I am sure I've read somewhere that it is possible to use a single wifi logger to collect data from both inverters (I have a wifi dongle on one of the inverters, but not on the other). I am guessing I can connect the two inverters together (hopefully by linking the two RS485 ports - as both have their canbus ports connected to batteries). Is it as simple as this? Or am I being over-optimistic?

I utilise the data for my Home Assistant panel - so I can see at a glance whether I'm importing/exporting and how much power the inverter is consuming or providing. Would be good to duplicate this for the second inverter.
