522kWh 240kW Liquid Cooled DirectCurrent Charger Battery Storage High Power Fleet Infrastructure Deployment Commercial

Overview

The 522kWh 240kW Liquid Cooled DirectCurrent Charger Battery Storage is a factory-integrated PV BESS charging station uniting 522kWh of LFP storage with a 240kW DC charger. The all-in-one cabinet embeds EMS control, solar energy storage and bidirectional power flow to serve commercial fleet electrification with minimal on-site assembly. This consolidation delivers predictable performance, faster deployment and a smaller land requirement than distributed systems, which is critical for depots and forecourts where space and grid capacity are both scarce. The 522kWh LFP reserve decouples charging demand from the utility connection, so the 240kW output can charge vehicles at full rate while the EMS shifts load away from expensive peak windows and prioritises stored solar energy.

The all-in-one cabinet coordinates PV harvesting, 522kWh LFP storage and 240kW DC delivery under a single EMS that maximises renewable self-consumption. Off-grid capability keeps commercial fleet vehicles moving during outages, while peak shaving and factory integration reduce both energy bills and deployment time. The bidirectional PCS shifts inexpensive off-peak and solar energy into the 522kWh reserve and discharges it when tariffs and demand peak, turning the storage asset into an active cost-control tool. Housed in a weatherproof, IP-rated enclosure with full BMS and thermal protection, the integrated station complies with IEC 61851 and IEC 62619, delivering dependable high-power charging and grid-friendly operation from one compact, quickly installed unit.

Key Advantages

• All-in-one integration: battery, PCS, EMS and DC charger are factory-assembled and pre-commissioned in one cabinet, enabling fast, low-risk installation and a single point of maintenance accountability.
• Space efficient: the compact integrated footprint suits commercial fleet depots, retail forecourts and urban charging hubs where land and grid capacity are limited.
• Peak shaving: 522kWh LFP storage and a bidirectional PCS shift load away from expensive peak periods to cut demand charges and stabilise on-site power.
• Solar-ready: MPPT PV input maximises renewable self-consumption and reduces long-term energy cost by storing daytime generation for later charging demand.
• High-power charging: 240kW DC output delivers rapid charging with CCS2 connectors and OCPP 1.6J connectivity for mixed commercial fleets and public users.
• Resilient operation: seamless off-grid and grid-connected modes, LFP safety, integrated thermal control and IP55 protection keep the station available through outages and harsh weather.

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.

Technical Specifications

Application Scenarios

• Commercial fleet depots requiring high-power charging while reducing grid demand charges through stored solar and off-peak energy, keeping vehicles ready between duty cycles.
• Off-grid and weak-grid locations where solar energy storage sustains continuous EV charging without a strong utility connection or costly grid reinforcement.
• Public and highway charging hubs needing scalable PV BESS charging station capacity that eases pressure on the local grid during busy periods.
• Microgrid and demand-management projects balancing renewable generation, battery storage and EV loads to optimise energy cost, resilience and reliability.
• Retail, workplace and depot sites favouring a single, quickly installed all-in-one integrated cabinet with a compact, low-maintenance footprint.

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.
