Core Advantages of the GNEE 30kW 51.2kWh Outdoor Energy Storage Cabinet
Built for Harsh Outdoor Environments
IP55 protection against dust and driving rain, an anti-corrosion coated steel enclosure, and a –20°C to +55°C operating window (with optional air conditioning for extreme tropical heat) keep the system running through desert summers and monsoon seasons alike - the conditions that kill ordinary indoor-designed battery racks within two years.
Intelligent EMS with Remote Monitoring
The built-in EMS supports solar self-consumption, time-of-use arbitrage, peak shaving, and backup priority strategies - configurable from a local touchscreen or remotely via the 4G/WiFi cloud platform. Fleet operators can monitor cabinet-level status, alarms, and revenue data for multiple sites from one dashboard.
Scalable from 51.2kWh to MWh-Class
Start with one cabinet, expand up to 8 cabinets in parallel (409.6kWh, 240kW) as your load grows, or step up to GNEE's containerized BESS and box-type substations for utility-scale projects. Your investment today is the first building block of a larger microgrid tomorrow.
True All-in-One Integration - 70% Less On-Site Work
Inverter, LFP battery, BMS, EMS, distribution unit, and fire protection are pre-wired and factory-tested. Your site crew only needs to mount the cabinet, connect PV/grid/generator/loads, and power on. For remote projects where skilled electrical labor is scarce and expensive, this plug-and-play outdoor battery backup eliminates the biggest cost and risk in the whole installation.
One-Stop Power Equipment Supplier, Not a Cabinet Assembler
We manufactures the complete power chain around your storage system: pad-mounted and distribution transformers, medium/low-voltage switchgear, distribution boxes, and compact box-type substations. Whether your project needs a step-up transformer for PV integration, a custom LV panel for load distribution, or a full containerized substation - you source it from one accountable manufacturer, with matched interfaces and a single warranty path.
Application Scenarios: Where a 30kW 51.2kWh Battery Backup Pays Back Fastest
Backup Power for Commercial Sites in Weak-Grid Areas
Factories, cold-storage facilities, hotels, hospitals, and commercial buildings in weak-grid regions across Africa, Southeast Asia, the Middle East, and Latin America lose real revenue with every outage. The 30kW/51.2kWh cabinet detects grid failure and transfers to battery power in under 10 milliseconds - fast enough that computers, refrigeration, and production lines never notice. Paired with solar PV, it recharges for free every sunny day instead of burning diesel.
Off-Grid Power Supply for Farms, Telecom Stations, and Remote Facilities
Where no utility grid exists, the cabinet forms a standalone power station with a PV array and an optional diesel generator as last-resort backup. A typical configuration - 30kW PV + 51.2kWh battery - reliably covers 120–180 kWh of daily consumption, ideal for irrigation pumping, farm processing, telecom base stations, mining camps, and rural clinics.
Solar Self-Consumption and Peak Shaving for Industrial Users
In markets with high feed-in tariffs lower than retail tariffs, or with demand charges, the system stores midday solar surplus and discharges during evening peaks - cutting electricity bills by 30–60% for facilities on time-of-use tariffs. Peak shaving also flattens demand spikes that trigger expensive maximum-demand penalties.
Microgrid Energy Storage Unit
The cabinet serves as the core storage node in a small microgrid, coordinating PV, grid, generator, and loads through its EMS. Multiple cabinets parallel into larger microgrids for industrial parks, island grids, and remote communities.

FAQ
How long can a 51.2kWh battery backup run my loads?
At the full 30kW output, the usable energy (≈48.6kWh at 95% DoD) runs about 1.6 hours. For typical mixed commercial loads of 8–12kW, it covers 4–6 hours - and with solar charging during the day, the backup becomes effectively unlimited in sunny regions.
Can the cabinet work without any grid connection?
Yes. In off-grid mode it forms the grid together with the hybrid inverter, supplying PV, generator, and loads. Grid connection is optional, not required.
Can I expand the system later?
Yes - up to 8 cabinets parallel to 409.6kWh / 240kW, and GNEE also supplies larger containerized BESS from 100kWh to MWh scale for future growth.
Do you support OEM/ODM and project customization?
Yes. Battery capacity, system voltage, frequency (50/60Hz), color, logo, and inverter brand (Deye, Growatt, Solis, or equivalent) are all configurable to match your market and tender requirements.
