Quick and easy to install. As long as there is a hot water tank with immersion heater, there is no need for any replacement. Typically installed by an electrician in a couple of hours – no mess and no fuss. No lengthy or unsightly cables are involved. The Energy Meter also runs on mains electricity, ensuring reliable, uninterrupted communication for trouble-free and low energy use without having to replace batteries. Free-E adjusts the flow of energy to the immersion heater automatically as home consumption varies. This ensures only excess generated power is used to heat the domestic hot water tank. Even on cloudy days, Free-E adjusts the immersion consumption quickly to ensure it only uses free electricity. No need to monitor the system once installed – simply enjoy using free hot water. However, a clear back-lit display shows the PV generation breakdown for the property of export, import and energy used for hot water generation, if required. Free-E is made from high-quality components but, in the unlikely event of a problem, every Free-E comes with a three-year warranty for complete peace of mind. Unlike many other systems, Free-E uses innovative technology to ensure it does not create any electronic interference. Therefore, it is fully compliant with European regulations (EMC). Intuitive commissioning allows for simple set-up, while a self-check feature confirms correct installation of the Energy Meter. An intelligent self-protection system prevents over-current and overheating. Plus, wireless communication – using 868 IBM band with listen-before-talk technology – allows trouble-free installation of multiple systems in a small area.
