What is a microgrid system?

A microgrid is a localized energy system that can operate independently from the main grid. It typically includes generation sources (solar, wind, generators), energy storage, and smart controls to optimize energy production, consumption, and storage for a specific facility or community.

What are the benefits of energy storage systems?

Energy storage systems provide multiple benefits including: reducing energy costs through peak shaving, providing backup power during outages, improving power quality, enabling greater use of renewable energy, participating in grid services, and increasing energy independence.

What are mobile solar containers used for?

Mobile solar containers are transportable energy systems used for: construction site power, remote operations, event power, emergency response, agricultural operations, mining sites, and temporary facilities where grid connection is unavailable or impractical.

What is the difference between BESS and ESS?

BESS (Battery Energy Storage System) specifically refers to systems using battery technology for energy storage. ESS (Energy Storage System) is a broader term that includes all types of energy storage technologies including batteries, pumped hydro, compressed air, flywheels, and thermal storage.

What types of batteries are used in energy storage?

Common battery types for energy storage include: Lithium-ion (Li-ion), Lithium Iron Phosphate (LFP), Flow Batteries, Lead-acid, and emerging technologies like Solid-state batteries. The choice depends on application requirements, cost, lifespan, and performance characteristics.
