PV+ESS+EV Charging Solution

CORE BENEFITS

Make Clean Energy, Storage and Charging Work as One

Lower the Cost of Site Energy

The EMS continuously coordinates solar output, charging demand, electricity tariffs, battery SOC and grid capacity. Solar power is used first by chargers and other site loads. Surplus generation charges the battery, while low-tariff grid energy can also be stored within the site’s capacity limit. During high-price or high-load periods, the battery discharges alongside solar and the grid to reduce peak grid demand.

INTEGRATED ENERGY SYSTEM

One Control Layer Across Generation, Storage and Charging

The EMS monitors solar output, battery SOC, charging load, electricity price and grid power in real time, then adjusts the direction and level of energy flow automatically.

Solar PV

Local renewable power for chargers and site loads.

Battery Storage

Stores surplus solar or off-peak grid energy.

Power Conversion

Manages bidirectional conversion between battery and AC bus.

EV Charging

Delivers AC or DC charging within available site power.

Energy Management

Executes dispatch, peak shaving and capacity control.

SMART ENERGY DISPATCH

Dynamic Decisions Based on Real-Time Site Conditions

Dispatch is continuously optimized around solar output, battery SOC, tariffs, grid limits and vehicle demand.

01

Solar First

Solar supplies active chargers and site loads first. Surplus energy charges the battery or, where permitted, is exported.

02

Off-Peak Charging

The battery can charge from the grid during lower-tariff periods while total site demand remains within its limit.

03

Battery Peak Shaving

Stored energy supports charging peaks and reduces maximum power drawn at the grid connection.

04

Grid Support

The grid supplies remaining demand when solar and stored energy are insufficient, maintaining reliable charging service.

FREQUENTLY ASKED QUESTIONS

Planning a Solar, Storage and Charging Project

Can battery storage completely replace a grid upgrade?

It depends on the charging load profile, available grid capacity, battery output and required discharge duration. Storage can often reduce or defer an upgrade, but sustained high-power charging may still require additional grid capacity.

Does every integrated charging solution require solar PV?

No. Battery storage and charging equipment can operate as a standalone storage-and-charging system. Solar PV can be added where site conditions allow to reduce grid purchases and increase renewable-energy use.

Can chargers continue operating during a grid outage?

Only a system designed for island operation, with suitable switching equipment and sufficient stored energy, can continue supplying selected chargers or critical loads during an outage.

How are battery power and energy capacity determined?

Sizing considers the grid-power shortfall, charging-peak duration, tariff structure, solar production, cycling strategy and the required SOC reserve.

Does zero-export control remove the need for grid approval?

Usually not. A system electrically connected to the public grid must generally comply with local approval, protection, metering and power-quality requirements.
