Warranty

Powerstar voltage optimisation units have up to 10 year warranty from date of purchase.

Our warranty includes parts and labour for the period. It excludes damage due to overloading the Powerstar system (i.e. if your company purchases and installs a 300kVA Powerstar system and loads it to 400kVA, this will damage the system).

We 100% guarantee how much you will save 

Minimum savings are guaranteed as per our proposal.

If you do not achieve the full guaranteed saving percentage (i.e. you achieve 9% instead of the guaranteed 10%) then we will provide a one-off payment to compensate for the difference between your actual savings and our guaranteed savings. (based on the site and usage remaining the same).
