Industrial and Commercial Energy Storage System

GreenMore commercial and industrial energy storage systems cover storage inverters, outdoor integrated cabinets and containerized BESS, with flexible configurations from 50 kW / 100 kWh to multi-MWh. With conversion efficiency up to 98.7%, each system helps companies cut demand charges and peak tariffs, protect production continuity, shorten payback time and move toward low-carbon operation. What Commercial Storage Does Peak shaving and arbitrage Discharge at high-price peaks and charge in low-price valleys to lower the electricity bill. Backup and power reliability Carries critical loads through outages and voltage dips so production is not interrupted. PV self-consumption Stores surplus on-site solar for use after sunset and raises renewable share. Microgrid and grid services Supports off-grid sites and can provide frequency and capacity support to the grid. Configuration Range Form factor Typical scale Best for Outdoor cabinet 50 kW / 100 kWh and up Factories and commercial buildings with limited footprint. Integrated outdoor unit 100 kW to several hundred kWh Fast deployment of PV-plus-storage at a single site. Containerized BESS MWh to 15 MW / MWh Industrial parks, utilities and large microgrids. System Features Safe and Reliable Multi-layer protection against overcharge, overload and short circuit, with manual DC-input and AC-grid disconnection, a one-button emergency stop and redundant AC/DC control power. Efficient and Flexible A wide DC input range, efficiency up to 98.7%, MPPT tracking accuracy of 99.9% or higher and new-generation low-loss IGBT devices reduce conversion losses versus earlier designs. Wide Operating Range Operates from −40 °C to +60 °C and supports derated operation at altitudes of 3,000 m and above. Smart and Economical EMS monitors and schedules the system automatically for a design life of more than 25 years, while outdoor cabinet kits are fast to install and maintain. System Connection Diagram Related Case South Africa — 1 MW / 2 MWh Industrial & Commercial Storage For manufacturer Barloworld, production electricity made up the majority of energy costs. To bring those costs under control, the company installed a 1,000 kW / 2,000 kWh storage system using two GreenMore GM-LEG500K PCS units. The system manages peak loads intelligently, shifts maximum possible demand away from peak periods and lowers overall energy expenditure. Turnkey Service GreenMore supports the full lifecycle — site survey and load analysis, feasibility and design, equipment supply, installation, grid acceptance and O&M. Systems are sized to each site's tariff structure, load profile and space, from standardised outdoor cabinets to fully custom containerized solutions. The overall design targets a 25-plus-year service life; PCS, EMS and lithium battery components carry a 3-year warranty. Frequently Asked Questions What is a commercial battery energy storage system? It is a rechargeable lithium battery system, paired with a power-conversion system and energy management, that stores electricity for commercial or industrial sites. It is used to cut peak charges, store solar, provide backup and earn arbitrage revenue. How does commercial storage reduce energy costs? The system charges during low-price periods or from on-site PV and discharges during expensive peak periods, lowering both energy and demand charges. Savings depend on the tariff structure, load profile and system sizing. Can it keep production running during a power outage? Yes. Configured for backup, the BESS detects the outage and supplies critical loads from stored energy, switching automatically and restoring to the grid without interrupting essential equipment. Should I choose an outdoor cabinet or a containerized system? Outdoor cabinets suit smaller capacities and sites with limited space, with fast on-site installation. Containerized systems suit MWh-scale storage, offering factory integration, easier scaling and lower balance-of-system cost for large projects. How efficient is the power-conversion system? GreenMore PCS reach up to 98.7% conversion efficiency with MPPT tracking accuracy of 99.9% or higher, and low-loss IGBT devices keep round-trip energy loss to a minimum. What warranty and support are provided? The overall system is designed for a 25-plus-year service life, while PCS, EMS and lithium battery components carry a 3-year warranty.
