In this video, I show you a power controller for resistive loads that will allow you to harness the surplus energy from your photovoltaic installation in your electric water heater or a conventional radiator. It's a recently developed device that will add a lot of value to your photovoltaic installation. Instead of exporting the excess photovoltaic energy from your installation, you can divert it to your electric water heater so you can have free hot water with those surpluses. Along with the power controller, I show you a smart meter, which will be responsible for indicating how much surplus energy you have in your photovoltaic installation. I'll leave you the link to the manufacturer's website in case you want to learn more. https://www.iammeter.com/ I hope you find the video useful.
