Features

  • High-capacity LiFePO4 storage supports commercial duty. The cabinet packs energy for factories, shops and micro-grids, sustaining daily charge and discharge.
  • Engineered thermal management sustains throughput. Active air cooling and monitoring maintain safe cell temperature under sustained commercial cycling.
  • Integrated EMS delivers peak shaving and backup. It coordinates PV, battery and load for demand-charge reduction, time-of-use arbitrage and seamless backup transfer.
  • Modular architecture scales with the project. Capacity grows by adding cabinets or racks without replacing core components as the site requirement evolves.
  • Remote monitoring enables proactive operation. Over CAN/RS485 operators track health, energy flow and alerts from a central platform.
  • Multi-level safety protects the installation. Cell, module and system protection safeguard the cabinet for continuous commercial use.

Applications

  • Commercial & Industrial Backup: Powers essential loads such as lighting and equipment during grid outages.
  • Peak Shaving: Releases stored energy during high-tariff hours to cut demand charges.
  • Solar Self-Consumption: Pairs with PV through integrated MPPT to store daytime solar for later use.
  • Outdoor & Remote Sites: IP54 outdoor cabinet suits yards, depots, and sites without indoor space.
  • Microgrid & Off-Grid: Supplies buffered three-phase power where grid access is limited.
  • Small C&I Facilities: Compact footprint fits stores, workshops, and branch sites with limited room.

Energy Management & System Architecture

The SW-eBock-200F is built around 314Ah LFP cells that store 200.96kWh and release it across a 500–730Vdc output range with up to 157A of continuous charge and discharge current. The integrated PCS converts the DC battery energy into AC for site loads, while the built-in MPPT captures solar and the STS manages transfer between sources.

An energy-management layer coordinates charging and discharging to make the most of stored energy, drawing from PV or the grid and serving connected loads. Intelligent control keeps the air-conditioned cabinet within its operating window, balancing generation, storage, and consumption so the system runs efficiently through daily commercial cycles.

Grid, Backup & System Integration

The SW-eBock-200F supports grid-connected operation and can back up essential loads through its integrated STS, keeping equipment running when the utility supply drops. With IP54 outdoor protection and a compact footprint, it integrates into existing C&I electrical setups without a dedicated battery room.

For savings, the cabinet enables peak shaving by discharging stored solar during expensive tariff periods and supports solar self-consumption through its MPPT. Parallel expansion lets operators add cabinets to build a larger bank, and the integrated architecture can combine with PV or generators as the site's energy needs grow.

Warranty

LiFePO4 batteries for 5 years, hybrid inverters for 2 years, and solar panels under the supplier policy of a 10-year product warranty plus 30-year linear power warranty. If you experience any quality issues within the applicable warranty period, please contact us and we will arrange a replacement or repair promptly.

Frequently Asked Questions

Can this cabinet be installed outdoors at my site?

Yes. The SW-eBock-200F is an outdoor-rated air-cooled cabinet with IP54 protection for a cool, ventilated location, and its compact 1200×1250×2050mm size fits space-limited sites.

How much energy does it store and what can it power?

It stores 200.96kWh from 314Ah LFP cells and delivers up to 157A continuous charge and discharge across a 500–730Vdc range, covering essential commercial loads during outages or peaks.

Can I add more cabinets to increase capacity?

Yes. The cabinet supports parallel expansion, so you can connect additional units to grow stored energy and current as your site's demand increases.

How is the battery protected from overheating or fire?

It uses multi-level safety with fuse protection and a two-stage fire-suppression system, plus air-conditioned cooling and an innovative temperature design that helps extend battery life.
