We are totally dissatisfied with Harrisons. We opted for a GivEnergy Battery (because Musk is a tyrant) and 14 Aiko panels and have had no savings at all, plus we keep having short power outages as evidenced by all the appliances having to be re-set, approximately once a week. They say it is the data upgrades that are causing it, or can you send a photo of the problem, but the technicians and sales people have no experience of the GivEnergy product. It turns out we were the first ones to install it with the team in Auckland, although they only informed us of that when they had the head honcho overseeing the installation to ensure the first one went well. It didn't. They had to re-wire their initial job when we were plunged into darkness the next day. They don't know anything about the product, they don't provide any satisfaction via their call centre, they have no advice on how to set up the app to maximise our savings, no follow-up on questions asked, no idea of the optimal reserve setting for the battery or why. What a waste of $25K. Clearly just a process of selling in the product and nothing else matters when they have the money. If they had a zero option I would be giving that.
