Full operation without replacing transformers or upgrading the grid connection

Electromobility without grid upgrades: a smarter way forward

The adoption of electromobility does not have to mean costly grid reinforcement. PV SERVICE PLUS demonstrates that by combining large-scale battery storage, rooftop photovoltaics, and intelligent energy management, it is possible to operate electric vehicles even where grid capacity is limited.

A major public infrastructure operator is preparing the transition to a sustainable, zero-emission fleet. The electrification plan includes electric trucks, but the site is limited by a grid connection of just 110 kW and 160 A, which is insufficient for modern charging infrastructure.

PV SERVICE PLUS designed a solution that enables full operation without replacing transformers or upgrading the grid connection. The system integrates battery storage, photovoltaic generation, and a proprietary EMS (Energy Management System) that controls energy flows in real time and optimizes costs.

The installation includes ten Huawei CNI battery units operating as a single system, delivering 1 MW of power and 2 MWh of capacity. This supports nine AC charging stations (18 charging points) and one DC fast charger serving two vehicles simultaneously.

A 99 kWp rooftop solar system covers part of the daily consumption and charges the batteries when vehicles are not present. Using locally generated electricity improves operational efficiency and increases energy independence.

The EMS system considers operational schedules, vehicle departures, weather forecasts, and energy market signals. The entire solution is modular and ready for future expansion.

This approach is ideal for municipalities, public services, transport companies, and industrial sites where grid capacity is insufficient. With smart energy management and storage, electromobility infrastructure can be deployed without waiting for grid upgrades.

It is not just a technical solution—it is energy freedom, giving investors full control over consumption and costs.
