eSpire 280 Energy Storage System

Safe Technology & Multi-level Protection

The solution uses the best-in-class Tier 1 Lithium Iron Phosphate (LFP) chemistry for
the highest level of safety, thermal stability, and reliability; An integrated, multi-level
Battery Management System (BMS) monitors, optimizes, and balances the system.

Advanced Liquid Cooling for the Extended Battery Lifespan

The unique liquid cooling system optimizes the battery thermal performance by 3
times, which extends the battery lifespan and increases your investment.

Built-in Microgrid Controls with Adaptive EMS / Fleet Management

Ability to integrate with solar, genset, wind, micro-turbines, utility, or other distributed
energy resources. Intelligent software to reduce electricity cost, prepare for resiliency,
and maximize return on investment. Remote operation & maintenance.

Easy & Flexible to scale (Easy scalability)

This outdoor rated, modular solution can be expanded up to 4.2 MWH capacity
easily (Max. 15 unit in parallel).

Turnkey System for Fast Install

Fully integrated, pre-configured package system reduces on-site installation
time; includes inverter(s), battery trays, racks, BMS, microgrid Controller,
HVAC, fire suppression, and outdoor rated enclosure. Off-grid and Back up
package available.
