Solar power is a suitable energy source that helps charging stations reduce their dependence on grid power and allowing them to further optimize their electricity usage and reduce costs.

​Delta provides a series of residential and commercial photovoltaic inverters that can convert solar power to AC power with max. 99% energy efficiency. This, in addition to the standard grid, can be utilized to supply energy to connected EV chargers or energy storage devices.

To prevent sudden impacts on the grid, an energy storage system combining a power conditioning system (PCS) with a battery system can help EV charging station with peak shaving and load shifting functionality.

The Delta Power Conditioning System (PCS) is a bi-directional energy conversion inverter that converts power between energy storage and grid and manages power quality. Featuring high availability and configurability, it supports grid applications and controls energy dispatch exactly when required.

Delta offers a series of AC and DC chargers from 7 kW (AC) for home charging, 22 kW (AC) and 25 kW (DC) for commercial charging, to 100 and 200 kW (DC) public fast charging.

With different power ratings, interfaces, OCPP protocol support, and authorization management, Delta’s EV chargers are suitable for all charging sites and applications, providing better features for EV drivers.

To help charging service providers balance electricity safety, reasonable costs and service accessibility when building EV charging infrastructure, Delta includes EV chargers into the scope of load management and energy dispatching from the perspective of high-energy-consuming equipment. By charger grouping, prioritization, and scheduling to limit the maximum current output and leverage time-of-use electricity prices, DeltaGrid® EVM ensures reliable charging services under existing power facilities.
