Warranty Condition:

A certified electrical wireman or master electrician with a current Department of Labor registration is required to install all inverters and batteries. Once installed, a current electrical certificate of compliance (COC) for the installation of the solar or backup system is required. The installation needs to adhere to SANS 10142 in its entirety. If a warranty claim is filed without installation images, a current COC, and documentation that the item was installed by a licensed wireman or master electrician, it may be denied and become void.
