You can get it straight from the Inverter via Solar Assistant for the price of a Raspberry Pi3 and up also $58us 1 time fee (approx 150) using usb-a to usb-b cable that came with growatt. Plug and play, accessible from local ip or the cloud, also integrates to Home assistant via Mqtt, Joe.
@Sparky_SC has Solar Assistant hooked to his Growatt 5000esI've searched threads but haven't been able to confirm that Solar Assistant will work with Growatt, in particular the 3000TL LVM-ES. I wrote Pierre but haven't received an answer. He's out of the complete kits so I suppose I'll buy the Raspberry Pi when I'm in the US next week and hope for the best later.
