The Zappi EV charger is well-known for its eco-friendly features and its compatibility with renewable energy sources. However, some Zappi users have encountered a consistent issue – the charger not delivering the expected 7kW charging rate.

In this in-depth guide, we will explore common reasons behind the Zappi charger’s inability to consistently charge at 7kW and provide detailed solutions to ensure you enjoy a seamless and efficient home charging experience.

Understanding the Zappi Charger

To effectively troubleshoot and address the issue of a Zappi charger not reaching 7kW, it is essential to comprehend how the charger operates.

The Zappi charger is a smart and adaptable charging solution designed to optimize EV charging while minimizing the impact on your household’s energy consumption.

It adjusts its charging speed based on various factors such as the available power supply and the electrical load within your home.

Now let’s take a look at the most possible issues why your Zappi charger might have problems charging your vehicle at 7kW.

1. Check Your Electrical Supply

One of the most critical aspects affecting your Zappi charger’s charging speed is the power supply in your home. To charge at the desired 7kW rate, you must have a 32-ampere supply. Here’s what you need to do:

  • Reach out to your energy provider or a qualified electrician to verify that your home’s electrical supply is capable of supporting 32A charging.
  • Examine your electric service panel to ensure your home’s wiring and circuitry can deliver the required current without any limitations.

2. Monitor Household Loads

The Zappi charger is programmed to adjust its charging rate if there is a high demand for electricity elsewhere in your home. Here are steps you can take to address this issue:

  • Plan your Zappi charging to occur when other significant household appliances, such as dishwashers, washing machines, and heating systems, are not in operation. This ensures that more power is available for your EV.
  • Employ a smart plug to stagger the operation of these appliances to prevent high simultaneous loads.
