Is Deye or Sunsynk better for South Africa?

They are the same inverter. Sunsynk provides dedicated SA warranty support from Johannesburg; Deye relies on the importer/distributor. If your installer has a good relationship with their Deye distributor and can provide a 5-year warranty, Deye saves R3,000–R5,000 over Sunsynk for identical hardware.
