522kWh 240kW Integrated Solar Storage EV Charging Station For Commercial Fleet Infrastructure Deployment Projects

Overview

The 522kWh 240kW Integrated Solar Storage EV Charging Station is a transportable solar energy storage and charging unit that pairs 522kWh of LFP capacity with a 240kW DC output. As a compact PV BESS charging station, this mobile EV charger supports peak shaving, off-grid operation and fast redeployment across commercial fleet sites. Every subsystem, from the MPPT solar interface to the bidirectional PCS and the EMS, is packaged for travel, allowing crews to move charging capacity to exactly where it is needed without permanent installation. The 522kWh LFP reserve captures daytime solar yield and releases it on demand, so the 240kW charger keeps operating through outages, grid constraints and high-tariff windows that would otherwise stall electrified operations.

By storing solar power in the 522kWh LFP battery, the station decouples charging from grid availability and dispatches up to 240kW on demand. Integrated peak shaving lowers operating cost, and the rugged mobile enclosure enables rapid deployment for commercial fleet, construction and emergency response scenarios. The EMS continuously balances PV generation, battery state of charge and vehicle demand, prioritising clean stored energy before drawing from the grid. With CCS2 connectors, OCPP 1.6J connectivity and full bidirectional PCS control, this mobile EV charger behaves like a permanent fast-charging hub yet can be relocated whenever operational priorities change, protecting the investment against shifting site requirements.

Key Advantages

• Rapid deployment: the wheeled or skid-mounted chassis enables relocation and commissioning within hours, with no fixed civil works, trenching or transformer upgrades required before charging can begin.
• Grid-independent charging: the 522kWh LFP battery sustains extended off-grid sessions for commercial fleet vehicles at remote, temporary or weak-grid sites where a utility connection is absent or unreliable.
• Solar integration: MPPT PV input continuously replenishes stored energy, lowering diesel, fuel and grid reliance while maximising renewable self-consumption for the mobile EV charger.
• Peak shaving: the bidirectional PCS trims demand peaks and reduces utility demand charges by discharging stored solar energy during high-load and high-tariff windows.
• High-power output: 240kW DC charging with CCS2 connectors supports fast turnaround for buses, trucks, vans and mixed fleet EVs even in field conditions.
• Rugged and safe: an IP54-rated enclosure with LFP chemistry, multi-level BMS protection and thermal management ensures reliable operation across dust, moisture and wide temperature ranges.

Integrated Solar + Storage Charging

This integrated PV BESS charging station combines solar generation, lithium battery storage and DC fast charging in one system, delivering clean, resilient energy for commercial EV fleets and microgrids.

Peak Shaving and Demand Management

Intelligent energy management stores low-cost and solar power in the battery and discharges it during peak demand, reducing demand charges, easing grid load and avoiding costly infrastructure upgrades.

Off-Grid and Grid-Connected Modes

Operating both off-grid and grid-connected, the station charges electric vehicles reliably even where grid capacity is limited, making it ideal for remote depots and renewable microgrid deployments.

Safe, Rugged and Certified

Automotive-grade LFP cells, a multi-level BMS, thermal management and an IP54/IP55 weatherproof cabinet ensure safe 24/7 commercial operation, backed by global certification and remote monitoring.

Frequently Asked Questions

What battery capacity and charging power options are available?

MIDA integrated PV BESS EV charging stations are available in 120kWh/60kW, 200kWh/120kW, 261kWh/120kW, 418kWh/180kW and 522kWh/240kW configurations. The battery capacity (kWh) buffers solar and grid energy, while the charging power (kW) determines how fast connected electric vehicles are charged.

How does the solar + storage integrated charging station work?

The system combines photovoltaic input, a lithium iron phosphate (LFP) battery pack, a bidirectional PCS and an intelligent EMS. Solar energy is stored in the battery during the day and released to charge EVs on demand, reducing grid dependence and enabling fast charging even where grid capacity is limited.

Can the BESS charging station operate off-grid or grid-connected?

Yes. Both modes are supported. In grid-connected mode it performs peak shaving and demand-charge management; in off-grid mode the solar array and battery storage power EV charging independently, making it ideal for remote fleets, microgrids and areas with weak grid infrastructure.

How does energy storage reduce charging costs and demand charges?

The battery charges when electricity is cheap or from solar, then discharges during peak charging periods. This peak-shaving and load-shifting lowers demand charges, avoids costly grid upgrades and maximizes self-consumption of renewable energy, improving the total return on investment.

Is the lithium battery safe for commercial deployment?

Yes. MIDA uses automotive-grade LFP (LiFePO4) cells with a multi-level BMS, temperature monitoring, fire suppression and IP54/IP55 weatherproof enclosures, complying with IEC/UL safety standards for reliable 24/7 commercial and fleet operation.

Where are integrated BESS EV charging stations typically used?

They are ideal for commercial fleet depots, highway service areas, microgrids, remote and off-grid sites, logistics parks and locations with constrained grid capacity, delivering fast, clean and resilient EV charging with solar self-generation and energy storage.
