261kwh 522kwh 240kW CCS2 DC DC EV Charger Station with Solar Panel BESS Charging System

Product Overview

The MIDA 261kWh 522kWh 240kW CCS2 DC EV Charger Station is a solar-integrated battery energy storage charging system that combines high-capacity LiFePO4 storage with DC-to-DC fast charging. This BESS charging system pairs a bidirectional PCS with an intelligent EMS and rooftop solar panels to deliver clean, high-power EV charging anywhere.

Storing solar and off-peak grid energy in its 261kWh to 522kWh battery bank, the station dispatches up to 240kW of DC output for rapid vehicle charging. Its solar-integrated design supports peak shaving and off-grid operation, functioning as a self-sufficient microgrid charging asset.

Core Advantages

• Solar Panel Integration – Onboard PV coupling charges the BESS with clean energy, maximizing renewable self-consumption and enabling off-grid charging.
• 240kW DC Fast Charging – High-power CCS2 DC-to-DC output delivers rapid EV turnaround from stored energy.
• High-Capacity Storage – The 261kWh-522kWh LiFePO4 bank buffers energy for sustained high-demand charging.
• Peak Shaving – The EMS discharges stored energy during peak tariffs to reduce demand charges and grid strain.
• Liquid Cooling – Active thermal management sustains stable performance under continuous high-power operation.
• Long-Life LiFePO4 – Automotive-grade cells deliver 6000+ cycles with IEC62619-compliant safety.
• Smart EMS – Real-time monitoring coordinates solar, storage, and charging for optimal efficiency.

Frequently Asked Questions (FAQ)

How does a solar PV DC-DC charging pile work?

A solar PV DC-DC charging pile takes DC power directly from photovoltaic arrays (and optional battery storage) and feeds it to the EV through a DC-DC conversion stage, avoiding double AC/DC conversion losses. This maximizes solar self-consumption and lowers the cost of every kWh delivered.

Can the solar DC charger operate off-grid?

Yes. Off-grid and hybrid models combine solar input with battery storage so the station can charge EVs at remote sites, fleets and locations with weak or no grid connection, switching seamlessly between solar, storage and grid where available.

What happens when there is not enough sunlight?

The intelligent energy-management system automatically blends solar, battery storage and grid power to maintain a stable charging session. Priority is given to solar and stored energy, with grid power used only as a top-up, keeping charging uninterrupted day or night.

Which connector and protocol standards are supported?

Solar DC-DC piles support CCS2 as standard (CCS1 for North America), with OCPP 1.6J/2.0.1 for network management. This allows the solar charging station to join any smart charging or energy-optimization platform.

Does solar charging reduce operating costs?

Significantly. By generating and consuming clean energy on-site, a solar PV DC charging station reduces grid electricity purchases, cuts demand charges and improves ROI, while supporting corporate sustainability and carbon-reduction goals.

Is OEM/ODM and system sizing support available?

Yes. MIDA helps size the PV array, storage capacity and charger power for each site, and offers OEM/ODM customization for branding, connectors and regional certification.
