Installation of our Hybrid and Off Grid Solar System packages

As a battery manufacturer our focus in on the engineering and ongoing further development and making improvements to our product range. We have established partnerships around the country with solar based electrical contractors that can carryout the installation and commissioning of our solar packages. We require a 50% deposit to proceed with an application (with respect to grid connected systems) off grid systems do no require any pre-approvals and to procure and secure all the equipment required for the installation. Such as solar panels, mounting hardware, voltage optimisers, PV inverters, battery inverters and other components. We do not stock or keep any such equipment on our premises this is negotiated and purchased directly from the electrical wholesaler network once the deposit is paid and delivered to the electrical contractor nominated for the installation.

We require a further 30% deposit to be paid on or before the installation date so that the equipment can be delivered to site. The balance of 20% needs to be paid NET 7 DAYS after the completion of the installation and commissioning in full.

This 50% deposit is non refundable should the customer decide to cancel after 7 days of paying the deposit, as all equipment for the job would have already been procured from the wholesale network and this equipment is not able to be returned.
