50kW High-power Energy Storage System – Commercial & Industrial Peak Shaving Solution

   A 50kW high-power energy storage system is specially designed for small and medium-sized industrial and commercial facilities (supermarkets, office buildings, small factories), integrating lithium iron phosphate batteries and bidirectional PCS. Unlike low-voltage household energy storage, this system can discharge at full power within 2 hours and has a dynamic response of less than 40ms. This 50kW high-power energy storage system supports grid connection for self-use, demand-based electricity charge management, and islanding backup. It has a daily 2-charging and 2-discharging design, and is expected to have a cycle life of ≥6000 times. Compared with similar 50kW energy storage systems, its modular cabinets can be connected in parallel to expand capacity to 300kWh.

Core Parameter Table: 

- Rated power: 50kW
- Battery capacity: 100kWh ~ 200kWh (expandable)
- Battery type: LFP (lithium iron phosphate)
- Maximum efficiency: ≥ 94% (AC side)
- Protection level: IP54

Key selling points:

1. Intelligent Demand Management: Real-time monitoring of transformer load, automatic discharge to reduce peak load, and a 25-35% reduction in basic electricity charges.
2. Black Start Capability: After power grid outage, it automatically forms a microgrid to ensure power supply for critical loads.
3. Remote OTA Upgrade: BMS and PCS algorithms can be continuously optimized to extend system lifespan.

FY Solar - Full-Spectrum Solar & Energy Storage Partner | 10+ Years Factory Direct

Company Overview FY Solar is a vertically integrated solar energy and energy storage manufacturer with over 10 years of industry expertise. We own production lines for lithium batteries and solar panels under our proprietary brand, and serve as authorized distributors for select international brands - giving buyers access to the full solar value chain from a single, trusted source.

We specialize in serving distributors, wholesalers, solar installers, and EPC contractors who need competitive pricing, reliable supply, and professional technical support.

Manufacturing & Own Brand Two core product lines are manufactured in-house under our own brand:

Lithium Batteries: LiFePO4 chemistry, residential and commercial battery packs, scalable modular design for home, C&I, and off-grid applications. MOQ: 1 unit - the lowest barrier to entry for distributors testing new markets.

Solar Panels: Monocrystalline and bifacial modules, 100W–700W+. MOQ: 1 pallet (~20–31 panels depending on wattage) - ideal for small distributors and project-based procurement.

Factory-direct supply means: no middleman markup, direct quality control, and full OEM/ODM customization capability.
