Matthew happily took the time to explain what was possible and why, the options available. He lives and breathes this stuff, very knowledgeable, yet not pushy at all. The installers were first rate and did a great job with good consultation. The equipment has all worked without issues so far and we had a power meter installed in our switchboard so we get full information via the internet and the inverter. We purchased 6.6kW solar panels into a 5kW Fronious inverter, with Fronious power meter to monitor consumption, a Daikin US7 heat pump for heating and cooling and a Sanden heat pump hot water system. Our total energy consumed has dropped massively, sorry have not worked it out exactly, as well as the total cost of energy. Only have gas for cooking left to go. Give them a call and talk about what nan be done. Wayne
