Post Subject: Equi=Tech? Truly pure power?Posted by oxric on: 3/8/2011

I have come across this company mentioned in a preview on '6moons,' and the information on the company's website suggests that this is in theory really a complete solution, and one that makes sense even to the non-engineer that I am to AC problems.

It addresses the problem at the source in a manner which makes it less accessible than Purepower and also, in so doing, means that it does not fall in the neat category of domestically standard and approved electrical devices, although it is possible to obtain authorisation for its use in a domestic environment after appropriate authorisations have been obtained from the local health and safety authorities, correct notification of one's home insurance provider and use of an approved engineer/electrician. In short it requires substantial investment (about $10,000 for the basic 5WQ or $12,500 for the reviewed wall panel units in the US), delay in getting the necessary approvals and it is certainly to be considered a permanent solution.

As a matter of principle, but this is me, I object to throwing money at companies such as APS PurePower, which seem to have questionable quality control and fairly poor treatment of customers, actual or potential. On the other hand a complete solution that would cost even $13,000-15,500 inclusive of installation (not such a large amount when one considers that at least a couple of PurePower owners posting here required 3 of these units in their systems), is certainly a contender and one that I would use if the installation is part of my long-term system and it delivers in terms of performance. Well, it would be nice if there was a distributor in Europe but I am sure that will happen in due course.

Here we have a much more interesting solution. Before anyone scrambles up the chimney screaming "But we do not know what it sounds like!," well that the point of this post, to see if anyone has actual experience of such a system, maybe in a professional environment, and whether they can comment.

For those who are allergic to 6moons and scientific jargon, I would briefly summarise, based on my reading of the technical data on their website, that balanced power operation means splitting 120v down two wires in opposite phase and seemingly in one fell swoop rejecting all ground and common noise problems outside the system.
