“Sales team was flexible and helpful. The installation was complicated but the installer went the extra mile to get it done. Needed support on a couple of settings, was happy to take my calls to help me.”

“The PSW team were responsive and helpful during the quote and pre-install stage answering all the niggly consumer questions swiftly. The install team were efficient and professional also in and out of the house in a couple of days, providing updates during the installation. Post install has been good too with the team contacting me to check on the system and ensure we are happy with it. Highly recommend PSW. They were recommended to me by a colleague and I'm very happy with the outcome. Well done PSW team. A good business delivering a great service.”

“From quote to installation in under three weeks. The crew were on time, tidy and talked me through the Tesla app before they left. Bills have gone from $480 a quarter to basically zero.”

“Got four quotes and PSW were the only ones who didn't pressure me. The itemised quote made it easy to compare exactly what I was getting. Install was done in a day and the follow-up service has been great.”

Battery StorageiStore battery explained: the 7kWh model for WA homes
If you've been quoted an iStore battery, or you already run one, there's a change worth knowing about. iStore is moving its home battery from the current 5kWh module to a new 7kWh model, and the two don't physically mix. This page explains what the iStore battery is, what the move to 7kWh entails, and where it sits compared to the batteries we fit in Perth homes.

EV ChargingFronius Wattpilot Flex: the EV charger to match your Fronius ecosystem
If your home already runs on a Fronius inverter, the Wattpilot Flex is the charger built to work with it. It charges your car from the surplus solar your Fronius system is already measuring, switches itself between one and three phases to catch every bit of that surplus, and runs through one app. This is a reference page for our Fronius customers. Fronius isn't part of our core charger range any more, but plenty of Perth homes we've installed run on a Fronius inverter, and for those homes the Wattpilot Flex is the natural match. We supply and install it on request.
