Engineering before equipment
We begin with the load and the operating requirement. Voltage, phase, current, starting demand, duty cycle, runtime, site conditions, mobility, and continuity expectations determine the configuration.
Company
We build the systems behind the infrastructure.
123eSolar is a mobile solar generator manufacturer and the mobile-power division of 123e—a family-owned engineering, manufacturing, and distribution company with roots in critical wireless infrastructure dating to 1998.
Our experience began with the components that connect and protect communications networks. It grew into custom manufacturing, technical distribution, digital procurement, and complete field-deployable power systems. Today, 123eSolar brings those disciplines together to solve a different part of the same challenge: keeping essential equipment operating wherever dependable utility power is unavailable, delayed, or impractical.
The 123e foundation
Built from nearly three decades of infrastructure experience.
The 123e story began in wireless infrastructure, where specifications matter, field conditions are unforgiving, and a small component can determine whether an entire system performs as intended.
Through 123eWireless, we learned to manufacture and supply technical products for engineers, network operators, contractors, integrators, and procurement teams. Through the 123e digital catalog and ecommerce operation, we built a practical bridge between engineering information, product selection, quoting, ordering, and fulfillment.
123eSolar extends that same operating philosophy from individual components to complete power platforms. We apply the discipline of infrastructure manufacturing—clear specifications, controlled configurations, serviceable construction, responsive support, and accountable delivery—to mobile energy systems.
Why 123eSolar exists
Remote power should be engineered as a system.
A field power requirement is rarely solved by choosing a solar panel, battery, inverter, or generator in isolation. The real problem includes the load, electrical interface, operating schedule, available solar resource, site conditions, deployment constraints, required autonomy, and consequences of an interruption.
123eSolar was created to address that complete problem.
We combine deployable solar generation, onboard energy storage, intelligent power controls, automatic backup generation, remote visibility, and a rugged mobile platform into one coordinated system. Each element has a specific role. The value comes from engineering those elements to work together around the application.
This is not residential solar placed on a trailer. It is purpose-built mobile power for equipment and operations that need to work beyond the practical reach of the grid.
What makes us different
One company from first requirement to field deployment.
Integrated power architecture
Solar production, energy storage, power conversion, controls, backup generation, monitoring, and the mobile structure are treated as parts of one operating system—not as unrelated components assembled after the fact.
Manufacturing accountability
Our background is in building technical products for infrastructure customers. That experience shapes how we approach component selection, assembly, testing, documentation, service access, and configuration control.
A direct path to a person
Customers can move from research to technical discussion, configuration, quoting, procurement, and support without being passed between disconnected organizations. The people helping define the system remain connected to the people responsible for delivering it.
The 123e ecosystem
Engineering, manufacturing, and procurement working together.
123eWireless
Infrastructure manufacturing experience
123eWireless designs, manufactures, tests, and supplies RF, fiber-optic, AISG/RET, and related connectivity products for demanding communications environments. That history gives the broader 123e organization firsthand experience with network infrastructure, field deployment, technical specifications, custom configurations, quality control, and delivery schedules.
123 Ecom
A practical procurement layer
The 123e catalog and ecommerce platform organizes a broad technical product library into searchable specifications, part numbers, account-based pricing, quoting, ordering, and fulfillment. It supports straightforward purchasing when a product can be specified and ordered directly.
123eSolar
Engineered mobile-power systems
123eSolar addresses requirements that cannot be solved from a shopping cart. Its role is consultative and engineering-led: understand the application, establish the design basis, select the appropriate architecture, define a controlled configuration, and prepare the system for its intended deployment.
How we work
Bring us the operating requirement.
The most useful first conversation is not about a model number. It is about what must be powered, where it must operate, how long it must run, and what must happen when conditions change.
01
Define the load
We establish the equipment being powered, its electrical interface, normal consumption, starting or surge demand, operating schedule, and criticality.
02
Understand the site
We consider location, solar exposure, temperature, terrain, access, mobility, deployment frequency, environmental conditions, and service constraints.
03
Establish the continuity requirement
We determine the required operating autonomy, acceptable interruption risk, backup strategy, monitoring needs, and response expectations.
04
Configure the system
We use the design basis to coordinate generation, storage, conversion, controls, backup power, communications, and the physical platform.
05
Document and support the build
The resulting configuration should be represented by its own approved specifications, drawings, options, documentation, and support information rather than by broad claims that may not apply to the delivered system.
Who we serve
Power for work that cannot wait for the grid.
123eSolar platforms are intended for commercial, industrial, institutional, and infrastructure applications where mobility, resilience, deployment speed, or remote operation matters.
- Wireless and telecommunications infrastructure
- Construction and temporary facilities
- Emergency response and disaster recovery
- Government and public infrastructure
- Remote monitoring and security
- Agriculture and field operations
- Industrial and environmental projects
- Temporary or transitional power requirements
Every application presents a different combination of load, location, runtime, and operational risk. That is why we focus on the engineering requirement before recommending a platform.
Our approach
Make sophisticated systems easier to specify, buy, and support.
The idea behind 123e has always been simple: technical work does not need to be made more difficult by the company supplying it.
For standard products, that means accurate information, searchable part numbers, responsive service, and an efficient purchasing process. For engineered systems, it means asking the right questions, explaining the architecture clearly, documenting what is being proposed, and staying available after delivery.
“Easy as 1-2-3” is not a claim that the engineering is simple. It is our commitment to make the customer’s path through that engineering clear.
Start a conversation
Tell us what has to keep running.
Send us the load, electrical requirements, operating schedule, site conditions, mobility needs, and continuity expectations. Our team will help turn those requirements into a defined mobile-power configuration.
