Executive Summary
- Location: Logistics Hub, Guangzhou, China
- Client: Third-Party Logistics (3PL) Provider
- Solution: Max Power PV-Storage-Charging All-in-One Station
- Key Features: Dual-gun Fast Charging, No Grid Upgrade Required, Solar-Powered
The Challenge: High Demand, Limited Grid Capacity
Our client in Guangzhou operated a busy logistics park with a growing fleet of electric delivery vans. They faced two major hurdles:
- Grid Constraints: The existing local transformer could not handle the high-power demand of multiple DC fast chargers.
- Rising Costs: Heavy daytime charging led to soaring peak-hour electricity bills.
- Installation Speed: They needed a solution that wouldn’t require months of civil engineering or complex grid permits.
The Solution: Solar EV Charging Station with Battery Storage
We deployed the Max Power Battery Storage EV Charging Station, a comprehensive solution that combines solar power generation, energy storage, and ultra-fast EV charging into a single unit.
1. Harnessing the Guangzhou Sun
Guangzhou enjoys an average of over 1,600 hours of sunshine annually. We installed high-efficiency monocycle solar panels across the warehouse rooftops. This energy is fed directly into the integrated storage system, significantly reducing reliance on the grid.
2. No Grid Upgrade Necessary
One of the standout benefits of this project was the avoidance of expensive grid infrastructure upgrades. The internal battery storage acts as a “buffer,” discharging high power to EVs even when the grid input is limited.
3. Dual-Gun DC Fast Charging
Equipped with dual-gun technology, the station allows two heavy-duty logistics trucks to fast-charge simultaneously. This ensures minimal downtime for the fleet and keeps the supply chain moving.

| Installation Time | Reduced by 60% compared to traditional grid-tied stations |
| Energy Cost | 40% reduction via solar self-consumption & peak-shaving |
| Grid Impact | Zero additional load on the local transformer |
| ROI | Estimated payback period of 2.5-3 year |
Why Choose Max Power for Logistics Parks?
Our All-in-One system is specifically designed for rapid deployment in high-traffic areas like logistics hubs, highway service areas, and remote industrial zones.
- Modular Design: Easy to transport and install.
- Intelligent EMS: Optimized energy flow between PV, Battery, and EV.
- Smart Remote Management: Real-time monitoring and cloud-based management via our integrated platform. Track energy yield, battery health, and charging sessions from anywhere, reducing the need for on-site maintenance.
- Peak-Shaving & Load Shifting: The system automatically charges the battery during low-cost hours or via solar, and discharges during peak price periods, further driving down the operational costs for the logistics park.
