British made quality. Micro-generation charging specialist with 3 charging settings to utilise surplus energy from your solar panels or other energy source! View Zappi's data sheet here
New V2.1 no longer needs an external hub for Wifi connection!
Fast Mode is the maximum current charged from energy via the grid, this should be the full 7.2kW unless the load management is limiting the charge current to protect the electrical installation.
ECO Mode tries to use as much surplus energy generated by your solar panels as possible. If the panels are not generating enough energy or you are using a lot of the surplus energy around your home then it will allow some energy from the grid to top up the charge to a minimum of 6amps. This means your car will always been charging even if it is only slowly.
ECO + Mode only allows EV charging from surplus energy genereated by your solar panels or other source of energy, so once the sun goes down or your batteries drain your EV will no longer charge. This is the slowest but most economical method of charging as you can charge for free!
