Renewable Energy
Over 36 Years of Building American Enclosures
Outdoor Electrical Enclosures for Solar, Wind, Battery Storage, and EV Charging Infrastructure
American Products designs and manufactures outdoor electrical enclosures built for the demands of renewable energy — rugged, weatherproof, and engineered to protect critical equipment in remote and exposed environments. Every enclosure is made in the United States, and our solutions are available in NEMA-rated configurations for projects requiring documented environmental protection standards.
From solar combiner protection and battery energy storage systems to EV charging station communications, we build enclosures that keep renewable infrastructure running reliably.
Outdoor Electrical Enclosures for Every Renewable Energy Application
Our renewable energy enclosure portfolio spans a range of deployment environments and application types. Each product line is matched to a specific use case — so you’re getting an enclosure engineered for your environment, not a general-purpose box adapted to fit.
AP Freedom — Controls, SCADA, and Communications Enclosures
The AP Freedom line is our primary enclosure for controls, SCADA systems, and communications equipment at renewable energy sites. Whether you’re protecting switchgear and combiner systems at a solar facility or housing the communications backbone at an EV charging station, AP Freedom delivers in a modular, field-deployable form factor — complete with climate-controlled environments and battery storage capability, including lithium battery configurations.
Available in three configurations:
AP Patriot — All-in-One Communication Backup System for Renewable Energy Sites
The AP Patriot is built around uptime. Designed for backup power, battery-adjacent, and SCADA applications, it’s a strong fit for battery energy storage system (BESS) deployments and renewable energy sites where reliable, continuous communication and protection is the priority.
AP Battery — Purpose-Built Battery Enclosures
The AP Battery line is our dedicated solution for battery storage applications, including outdoor battery enclosures for distributed energy storage deployments.
AP Fort — Walk-In Shelters for Utility-Scale Installations
When the scale of a renewable energy project calls for a walk-in shelter rather than a standard enclosure, AP Fort is the answer. Designed for utility-scale control rooms and large battery energy storage installations, AP Fort provides hardened, weatherproof protection for high-value equipment at the site level.
AP Fort is the right fit for:
- Utility-scale switchgear and combiner installations
- Large battery energy storage system (BESS) sites
- Remote renewable energy facilities requiring on-site equipment shelter
AP Minifort — Compact Enclosures for Distributed Nodes
The AP Minifort is a compact, NEMA 3R-rated outdoor enclosure built from aircraft-grade aluminum and designed for field deployment in demanding environments. At renewable energy sites, it’s a fit for distributed nodes along a combiner string and for edge communications enclosures at EV charging stations where a full-size shelter would be overkill.
C-Liberty — Small Distributed Enclosures for Renewable Applications
The C-Liberty is a compact, NEMA 3R and 4X-rated fiber distribution enclosure designed for high-density connectivity in a space-efficient footprint. In renewable energy deployments, it supports distributed communications nodes, including charger-to-network communication along EV charging corridors and smaller fiber nodes along a combiner string.
Custom Solutions — Engineered to Your Project Requirements
Renewable energy projects often have requirements that standard enclosures can’t fully address: unique footprints, specialized climate control, integrated power distribution, or site-specific configurations. Our engineering team can design and build an outdoor electrical enclosure around your exact specifications — manufactured in the U.S. and delivered on schedule.
We have worked with solar and wind energy companies to develop enclosures tailored to the demands of remote and environmentally exposed installations. That experience carries into every custom engagement.
Matching the Right Enclosure to Your Application
Renewable energy infrastructure spans a wide range of deployment types. Here’s how our product lines map to the most common applications in this market.
Switchgear and Combiner Systems and Communication
AP Freedom and AP Patriot are the primary enclosures for controls and SCADA systems associated with switchgear and combiner strings. For utility-scale installations requiring a walk-in control room, AP Fort is the right fit.
Battery Energy Storage Systems
EV Charging Station Communications
AP Freedom and AP Patriot handle the controls and communications backbone at the station level. For distributed communications nodes along a charging corridor — charger-to-network communication, edge enclosures at individual stations — AP Freedom’s modular configurations provide the flexibility needed.

Our background in telecom and electrical infrastructure gives us a deep understanding of what it takes to protect sensitive electronics in remote, outdoor, and environmentally demanding environments. That expertise translates directly into renewable energy enclosure solutions.
Flexible, Scalable Manufacturing
Renewable energy projects vary enormously in scale, from a single distributed node to a utility-scale installation with dozens of enclosures. We build to order in both standard and custom configurations, and our manufacturing flexibility means we can scale with your project.
NEMA Enclosure Ratings Explained
If you’re specifying an outdoor electrical enclosure for a renewable energy application, understanding NEMA enclosure types is essential. The National Electrical Manufacturers Association (NEMA) defines enclosure ratings that describe the level of environmental protection a product provides. Here’s what the most relevant ratings mean for renewable energy deployments:
NEMA 3R
NEMA 3R enclosures are designed for outdoor use and provide protection against rain, sleet, and ice formation. They are a common choice for renewable energy applications where protection from precipitation is the primary concern, but corrosion resistance is not required.
NEMA 4
NEMA 4 enclosures provide a higher level of protection than 3R — including resistance to windblown dust and rain, splashing water, and hose-directed water. They are suitable for outdoor renewable energy installations in more demanding weather environments.
NEMA 4X
NEMA 4X enclosures offer all the protection of NEMA 4, with the addition of corrosion resistance. A NEMA 4X stainless steel enclosure is a common specification for coastal or high-humidity environments where corrosion is a long-term risk — including many solar and wind energy sites.

Contact our team if you need help selecting the appropriate rating.
Are your enclosures BABA-compliant for federally funded renewable energy projects?
Our enclosures are manufactured in the United States. If your project has BABA compliance requirements, contact our team to discuss your procurement needs and we can provide the necessary documentation.
What is a NEMA 4 enclosure?
A NEMA 4 enclosure is a weatherproof electrical enclosure designed for indoor or outdoor use. It provides protection against windblown dust and rain, splashing water, and hose-directed water. It is a step above NEMA 3R in protection level and is commonly specified for outdoor renewable energy installations in demanding weather environments.
What is the difference between a NEMA 4 and NEMA 4X enclosure?
Both ratings provide the same level of protection against water and dust. The key difference is that NEMA 4X enclosures also offer corrosion resistance, making them the preferred choice for coastal installations, high-humidity environments, or any site where long-term exposure to corrosive elements is a concern.
Can you build a custom outdoor electrical enclosure for a renewable energy project?
Yes. We design custom solutions for renewable energy projects with specific footprint, climate, power, or integration requirements that standard enclosures can't fully address. Contact our team to discuss your project.
