Youda's off-grid LAB
0x70 and 0x371 come from the SEPLOS 1.0 document which says to be compatible with PYLON 1.3 and GoodWe 1.5. I had never managed to find the PYLON 1.3 protocol or higher that's why I named this protocol PYLON + in my application YamBMS because I couldn't really put a version number without having had an official document in my hands. I will now be able to update my code with the PYLON 2.0.5 protocol 😍 As you have discovered you must respond every second with an ID 0x305 what I called the inverter heartbeat in my code.

Deye Hybrid Product Series / Model Designation Codes
SG03 vs SG04 According to this video there is no difference in performance, the only difference is size and price. SG04 is more compact and cheaper.

Curious MPPT behavior
Hi, I noticed the same thing with my Deye SUN-6K-SG03LP1-EU. I spoke with the Deye service about this and they advised me to add optimizers 😐 But, since the latest firmware version: HMI: 0000-C369 MAIN: 0-4385-1515 A new “MPPT multi-point scanning” option has appeared. I haven't tested it yet but I hope it will help to have better behavior.
