The most common reason that your Splitvolt Splitter Switch has turned off (breaker tripped) during a charging cycle is because charging is set at a rate of more than 5.7KW, or 24 amps. Charging at rates higher than 5.7kw or 24 amps on a 30 amps circuit is against the recommendation of the NEC (National Electric Code).
Our splitter switch is equipped with an Thermomagnetic Breaker to prevent over-current, which prevents such misuse. When it trips, it is protecting your home!
Most car manufactures do not have an easy way to limit the charge rate, with the exception of Tesla and Polestar. While other car manufactures are adding this ability all the time, it is not universally available to all cars. Please contact your car dealership for charge rate settings, or contact our support at help@splitvolt.com.
If you know or can limit the charge rate to stay below 5.7kw or 24 amps, then it will usually resolve the breaker tripping issue.
