The Renault Twizy - Charging via a Variac for Solar

Charging the Twizy at home can sometimes be a problem with grid tied solar panels because the mains voltage can be too high. In this video I used a 20 Amp Variac to regulate the mains supply to an acceptable 230vac from our 251vac incoming to the house. This allowed the Renault Twizy to charge perfectly. I bought the Variac from Eastern Transformers and Equipment Ltd in the UK Open-Type Variable Autotransformer (Variac) for Panel Mounting 1ph 20A Renault Twizy - Won't charge if the mains voltage is too high.
