Solar Charging
Planning to charge with solar?
The E2 Core includes solar charging functionality as standard. It can prioritise excess solar generation and blend solar with grid electricity when required.
The E2 Flex provides the same core smart charging experience without solar functionality enabled by default. Solar charging can be added later through a software upgrade — without replacing the charger or arranging another electrical installation.
E2 Flex
Smart charging now, optional solar upgrade later.
E2 Core
Solar charging included from installation.

“Steve Meredith was the electrician who attended to this job for us. To say he was professional and went above and beyond to help us out is an understatement. Steve pointed us in the right direction as to what was needed and was not only spot on but helped us immensely as we didn't know what we didn't know. Thanks to Gibson Electric and to you Steve. Awesome work and truly appreciate your time.”
