How to determine Pool size


Does the price include installation?

No, the price doesn't include installation. Installations are all different and require varying length of cable, time and distances to be travelled. In addition to this installations need to be done by a qualified electrician to issue a valid Certificate of Compliance (COC) for your insurance. We will gladly recommend a qualified local installer, please ask your Sales Consultant for more information.

Do we offer installation?

No, but we do have recommended installers throughout Southern Africa who will be able to assist you with your installation and sizing your generator.

Does the price include delivery?

All prices exclude delivery. We will gladly get a price on delivery for you.

Do I need anything else to connect the solar panels?

You will need solar panel mouting brackets. These vary depending on the type of roof you have.
6m of cable is supplied with the kit, if you need more than this you'll need to purchase more.
Up to 16m = 4mm, 2 core cable
Up to 60m = 6mm, 2 core cable

If you use the wrong thickness of cable, the performance of the pump will be affected.
