The challenge
Charge fleets on your own power
EV charging adds large, peaky loads. Solar and storage keep those loads off the expensive grid peak.
Multiple chargers running together create demand spikes that raise grid charges and can exceed the connection limit.
Charging from the grid at peak hours undermines the cost case for electrifying a fleet.
Depots and car parks want to scale charging without a costly grid upgrade.
How it works
How solar EV charging works
PV, storage and chargers managed as one site under an energy management system.
- 01
Solar generation
Rooftop or carport PV feeds the site during the day.
- 02
Buffer storage
The battery stores surplus PV and buffers charging peaks.
- 03
Smart charging
Compatible charger controls can prioritise available PV and battery power according to the approved site logic.
- 04
EMS control
Project-configured load management coordinates the battery and chargers against the approved grid-connection limit.

PV + storage
Tongwei modules and Hithium C&I battery storage selected against the measured or forecast charging demand.
EV charging interface
EV chargers are not part of the current Sunket Supply product range; charger selection and local installation remain with a qualified charging partner.
Integration coordination
Battery, charger and EMS data points, protocols, control permissions and responsibility boundaries are confirmed per project.
FAQ
Frequently asked
Can I add EV charging to an existing PV site?
Existing PV can be integrated with chargers and storage where the equipment interfaces are compatible. Load-management controls and grid limits are confirmed per project.
Does the battery have to power the chargers fully?
No. The battery buffers peaks and shifts solar while the grid still contributes. Project-configured control logic coordinates the mix within the available permissions and power limits.
Which charger types are supported?
Compatibility cannot be stated by charger category alone. The local charging partner must confirm the charger model, protocol, EMS interface, power limits and approval requirements before the integrated control scope is agreed.
