120kW Solar DC EV Charger BESS 261kWh PV Energy Storage Commercial Fast Charging Station

120kW Solar DC EV Charger BESS 261kWh PV Energy Storage Commercial Fast Charging Station

Product Overview

The MIDA 120kW Solar DC EV Charger is a commercial fast charging station built around a 261kWh LiFePO4 battery energy storage system with integrated PV solar input. This BESS charging solution combines a bidirectional PCS, intelligent EMS, and CCS2 DC output to deliver clean, high-power EV charging while lowering grid dependence.

Storing solar and off-peak grid energy in its 261kWh bank, the station dispatches up to 120kW of DC fast charging on demand. Its solar-integrated PV design enables peak shaving and partial off-grid operation, functioning as a sustainable microgrid asset for commercial sites.

Core Advantages

• PV Solar Integration – Direct solar input charges the 261kWh BESS with clean energy, maximizing renewable self-consumption.
• 120kW DC Fast Charging – CCS2 DC output delivers rapid EV charging from stored energy without grid upgrades.
• Peak Shaving – The EMS discharges stored energy during peak tariffs to reduce commercial demand charges.
• Energy Storage Buffer – The 261kWh LiFePO4 bank smooths solar variability and supports sustained charging demand.
• Liquid Cooling – Active thermal management sustains stable output and extends battery life.
• 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.
