Zappi smart EV charger which uses surplus solar power

Stuart Wright

Had this installed last week.  Zappi charges your EV with surplus solar power.  Eddi powers your emersion heater with surplus solar power.   They work together and you can set which has priority.
                                Zappi doesn't start charging until it has a minimum of 1.3kW surplus, but Eddi can put any surplus into the emersion heater.
So Eddi will work until there is 1.3kW and then Zappi will take over.   When the car is fully charged, Eddi will then take all the surplus solar (up to the limit of the emersion heater which is usually 3kW) until the water is hot enough.
