Firmware fragmentation risk

Deye ships different firmware branches for different regions (African market SKUs vs EU CE-marked). Never mix — CAN protocol implementations differ. Always match the battery brand's Deye-approved firmware version.

Frequently asked questions

QIs Deye the same as Sunsynk?

Sunsynk is a South African brand OEM'd by Deye. Hardware is identical; firmware, warranty and support are Sunsynk's. In Africa, buy Sunsynk for local warranty; elsewhere Deye direct is cheaper.
