Charge HQ is a free utility and tools application available for iPhone users. Developed by Charge HQ Pty Ltd, this app aims to reduce your charging costs for electric vehicles (EVs) by utilizing solar or off-peak energy from the grid.

One of the key features of Charge HQ is its compatibility with existing equipment. Whether you own a Tesla or any other EV connected to supported wall chargers, you can use Charge HQ without the need for additional equipment. This makes it convenient for EV owners to take advantage of the app's capabilities.

The app allows you to charge your EV directly from your rooftop solar. Charge HQ communicates with your rooftop solar inverter or home battery to determine the amount of excess solar energy available for EV charging. It intelligently controls the charging process to match the available generation from your solar system.

In cases where there is insufficient solar energy during the day, Charge HQ can supplement the charging process by topping up from the grid during off-peak periods. This ensures that you always have sufficient charge for your daily driving needs.

By utilizing Charge HQ, you can charge your EV from the cheapest and greenest sources of energy, improving the payback on your rooftop solar system. Additionally, the app supports the development of more renewable energy generation and reduces fossil fuel use in EV charging.

Charge HQ also provides charge statistics, allowing you to view your charging history by day, month, or year. For those with solar, you can even see a breakdown of where the charging energy came from: solar, battery, or the grid.

Overall, Charge HQ is a valuable tool for EV owners looking to optimize their charging costs and reduce their environmental impact. With its compatibility with various equipment and intelligent charging control, it provides a convenient and efficient solution for utilizing solar energy for EV charging.
