The Deye MS-G(S)215-2H3 is a commercial and industrial (C&I) energy storage solution designed for medium- to large-scale solar and backup power applications. The system combines a 100 kW power conversion system (PCS) with a 215 kWh lithium iron phosphate (LiFePO4) battery pack in a single integrated outdoor cabinet. It is intended for factories, warehouses, office buildings, EV charging stations, microgrids, and other businesses seeking energy independence, peak shaving, and backup power reliability.

One of the standout features of the MS-GS215-2H3 is its integrated architecture. The system combines the Energy Management System (EMS), Power Conversion System (PCS), and Battery Management System (BMS) into one compact unit, reducing installation complexity and improving operational coordination. It supports both on-grid and off-grid operation, allowing businesses to continue running during grid outages while also optimising energy costs during normal utility operation.

The battery chemistry used is LiFePO4 (LFP), which is widely regarded as one of the safest and most durable lithium battery technologies. The system is rated for more than 6,000 charge-discharge cycles, making it suitable for long-term industrial deployment. Deye also integrates several safety features, including aerosol fire suppression, explosion-proof battery compartments, thermal management, and intelligent temperature control that keeps battery temperatures below 35°C for improved lifespan and performance.

The MS-G(S)215-2H3 delivers 100 kW AC output and supports up to 200 kWp photovoltaic input and 215kWh battery. The system allows customisation where MPPT requirement depends on the application such as DC coupling or AC coupling. The round-trip efficiency is approximately 88 percent, while inverter efficiency reaches about 97.6 percent. The system operates on a 380/400 Vac three-phase grid and supports Ethernet and 4G communication for remote monitoring and smart energy management. Businesses can use the EMS functions for peak-valley arbitrage, demand control, load tracking, anti-backflow protection, and backup power scheduling.

Scalability is another important advantage. Multiple units can operate in parallel, allowing installations to expand from a single 215 kWh cabinet to multi-megawatt energy storage plants. Up to 20 units can be connected for on-grid systems, reaching capacities of around 2 MW and 4.3 MWh.

The system is engineered for demanding outdoor environments. It carries an IP54 enclosure rating and C5 anti-corrosion protection, enabling operation in harsh industrial or coastal conditions.
