Welcome to the Solar Electric Vehicle Charging Guide with ChargeHQ! Ever dreamt of powering your car with the sun’s rays? With electric vehicles (EVs) marking a new era in eco-friendly travel, it’s crucial to know how to charge them in the greenest way possible. This guide is your roadmap to setting up an EV charging system that harnesses surplus solar energy, all seamlessly managed by ChargeHQ. Here, we’ll explore how to integrate a smart charger, compatible with the OCPP 1.6 protocol, into your setup. Managed by ChargeHQ, this system guarantees efficient, intelligent charging for your EV, blending cutting-edge green technology with smart innovation. Dive in and discover how to make your electric vehicle truly solar-powered!


How Does Solar Electric Vehicle Charging Guide with ChargeHQ Work?

Solar EV charging utilises solar energy captured by rooftop panels, directly charging your electric vehicle (EV). At the heart of this system are smart chargers, like OpenEVSE, and solar energy management systems such as ChargeHQ. These components work in harmony to ensure that your vehicle is consistently powered by clean, renewable solar energy. The smart chargers efficiently manage the energy flow, giving priority to solar power when it’s available, while ChargeHQ optimizes the overall energy usage. This integration not only fuels your EV with eco-friendly energy but also furthers the commitment to a more sustainable future.


Smart EV Chargers: The Gateway to Efficient Charging

Not all EV chargers are created equal. Smart chargers, unlike their ‘dumb’ counterparts, can be controlled through APIs or standards-based protocols like OCPP 1.6. This smart technology ensures your EV only uses excess solar energy, providing an efficient and cost-effective charging solution.


Smart Centralised Management: The Brain Behind the Operation

To effectively use your surplus solar energy, a smart management system is crucial. It aggregates data from your solar system and smart charger, calculating the excess solar energy available. This system then directs your charger to use only this surplus, ensuring your EV is truly solar-powered.


The Benefits of Solar EV Charging:

  • Eco-Friendly: This method maximises the use of renewable energy, reducing your carbon footprint.
  • Cost-Effective: By using surplus solar power, you decrease your reliance on the grid, saving on electricity bills.
  • Convenience and Control: Manage your EV charging remotely, giving you greater control and flexibility.


Hardware & Software Requirements

For a smooth solar EV charging setup, it’s essential to have the right hardware and software in place. Begin with a charger that’s compatible with the OCPP 1.6 protocol, ensuring seamless communication and efficient operation. Additionally, you’ll need an inverter that aligns with the requirements of your chosen management system. For instance, if you’re using ChargeHQ, refer to their compatibility guide to select an appropriate inverter. Here’s a straightforward guide to help you kickstart your solar EV charging journey:

Step-by-Step Guide to Setting Up Your Solar Electric Vehicle Charging Guide with ChargeHQ


Step 1: Install the OpenEVSE Charger

First, assemble the OpenEVSE charger. It’s designed for ease of use, but make sure a qualified electrician handles the installation for safety and compliance. Once installed, connect the charger to your Wi-Fi for easy access and control.
