The guide states that the table lists the registers accessible to the client \"on base 0\" and that the server ID is 255; its data-format chapter defines SINT32/UINT32 as high word first, so this file uses zero-based addressing with high word first. The PDF was read from a mirror of the vendor document (devicelib.my-gekko.com); the reference and revision are the vendor's own. The guide's section on the Modbus interface says the external system writes the degraded setpoints 4005/4006, so those two rows are RW here even though the register table marks the whole block read-only -- the seed follows the descriptive text and says so in the row descriptions. Left out: \"Energy Active TOT\" (3203) and \"Energy Reactive TOT\" (3219), both int64 in the guide, because the app has no 64-bit integer type; session energy (4012, uint32) carries the same value for a charging session. evcc's charger/schneider-v3.go drives the same addresses with function codes 03/06, which is how the table is to be read."
