261kWh 120kW Liquid Cooled DirectCurrent Charger Battery Storage High Power Fleet Infrastructure Deployment Commercial
Overview
The MIDA 261kWh 120kW integrated EV charger merges solar PV, an LFP battery, and smart energy management to provide dependable clean-energy charging for commercial fleet and public infrastructure deployment. As a complete PV BESS charging station, it captures renewable generation, stores it efficiently, and dispenses fast direct-current power through a CCS2 connector. The bidirectional PCS and EMS work together to enable peak shaving, off-grid operation, and optimized solar self-consumption across the entire charging site.
Rated at 261kWh storage capacity and 120kW charging power, this solar energy storage station supports peak shaving, load shifting, and resilient off-grid operation when utility supply is constrained. The 261kWh LFP battery sustains extended charging cycles, and the 120kW DC output keeps vehicles moving with minimal downtime. Its bidirectional PCS enables seamless islanding, so the PV BESS charging station continues serving commercial fleets during grid outages or capacity shortfalls. The onboard EMS continuously optimizes solar self-consumption, battery health, and dispensing schedules. This integration reduces total cost of ownership while ensuring the integrated EV charger meets stringent uptime and safety expectations across demanding commercial infrastructure deployments.

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.
