  • 1-Year Warranty
  • Warranties: All inverters and batteries must be installed by a qualified electrical wireman or Master electrician with a valid registration with the Department of Labour. A valid electrical certificate of compliance (COC) must be issued once installed, specific to the installation of the backup or solar system. The installation must be compliant with SANS 10142 and ALL its parts. Any warranty claim submitted without installation photos, a valid COC, and proof of a qualified wireman/master electrician installing the unit, can be rejected and will render the warranty claim null at the void.
