10MWh Modular LFP or Sodium Storage Systems — Uses 29% Less Land

Parasol Elite Power's BESS platform is sold in 10 MWh sets — two 5 MWh all-in-one 20 ft containers paired with one power booster container. Available in four C-rate configurations and a DC-output variant that eliminates the power booster entirely.

Product Overview

Purpose-Built for Behind-the-Meter Power

Every Parasol BESS deployment starts with a 10 MWh set: two 5 MWh all-in-one 20 ft containers, each housing cells, BMS, thermal management, and controls, paired with a single power booster 20 ft container for AC output. That's 3 containers per set versus the 4 required by traditional systems — a 29% reduction in land use that accelerates site permitting, reduces civil work, and lowers total installed cost. Scale to any project size by adding sets.

System Configurations

System Configurations

All four configurations store 10 MWh per set — the C-rate determines how fast that energy charges and discharges, setting the peak power output and discharge duration. Select the rate that matches your application's power and duration requirements.

DC output:power booster not required — (2) 5 MWh all-in-one containers only
0.25C
2.5 MW
4-hour discharge

Long-duration energy shifting, renewable firming, and peak demand management over extended windows. Ideal for utilities, microgrids, and facilities with broad daily load variation.

AC: (2) 5 MWh all-in-one + (1) power booster
0.3C
3 MW
~3.3-hour discharge

Balanced long-duration configuration for behind-the-meter energy shifting and backup applications requiring extended run time at moderate power output.

AC: (2) 5 MWh all-in-one + (1) power booster
0.5C
5 MW
2-hour discharge

The most common behind-the-meter configuration. Balances energy capacity with power output for peak shaving, backup power, and grid independence applications.

AC: (2) 5 MWh all-in-one + (1) power booster
1C
10 MW
1-hour discharge

High-power configuration for demand charge reduction, frequency regulation, and applications requiring full capacity discharge within one hour.

AC: (2) 5 MWh all-in-one + (1) power booster
DC Output Option

DC Output Configuration

Specify DC output and the power booster container is not required. Each 5 MWh all-in-one container delivers DC directly to your bus — reducing footprint, eliminating AC conversion losses, and simplifying integration with DC-coupled generation sources, EV charging infrastructure, and industrial DC loads.

No Power Booster Required

DC output eliminates the third container per set, reducing site footprint and capital cost.

Higher System Efficiency

Bypass AC conversion stages entirely. DC-coupled systems achieve higher round-trip efficiency than AC-coupled equivalents.

Direct DC Bus Integration

Native interface with DC microgrids, solar arrays, fuel cells, and DC loads without additional conversion hardware.

Key Features

Engineered for Behind-the-Meter Performance

LFP Cell Chemistry

Lithium iron phosphate chemistry delivers superior thermal stability, long cycle life, and safe operation in demanding industrial environments.

All-in-One 20 ft Container

Each 5 MWh container integrates cells, BMS, thermal management, fire suppression, and controls in a standard 20 ft ISO footprint.

Modular Scalability

3 containers per 10 MWh set versus 4 in traditional systems — 29% less land use. Add sets to reach any project capacity; each set is independently operable, simplifying phased deployment and future expansion.

Active Thermal Management

Precision liquid cooling maintains optimal cell temperature across all operating conditions, maximizing cycle life and performance.

Advanced BMS

Cell-level battery management system monitors state of charge, state of health, and temperature across every cell in the stack.

Parasol EMS Integration

Deep integration with the Parasol Energy Management System enables coordinated dispatch, demand response, and real-time optimization.
