Powering the Future of Energy Management with Reliable Display and Embedded Computing
Delivering rugged, high-performance displays and industrial-grade computing solutions for the next generation of energy infrastructure
The Challenge of a Decentralized, Digital Energy Grid
The global shift towards renewable energy, electric mobility, and smart grids creates immense opportunities, but also significant technical hurdles. Energy systems—from EV charging stations to solar inverters and battery storage units—are being deployed in harsh outdoor environments where standard electronics fail.
They demand absolute reliability, clear visibility in direct sunlight, and robust connectivity for remote monitoring and control. A failure in the user interface or control computer can lead to lost revenue, user frustration, and critical gaps in our energy infrastructure.
LMTEK delivers the rugged, high-performance core—sunlight-readable displays, all-weather touch screens, and industrial-grade SBCs—that enables you to build resilient and intelligent energy management systems.
Our Integrated Solutions for Energy Management
Explore how LMTEK's product ecosystem provides the critical building blocks for next-generation energy applications
Sunlight Readable
1000+ nits high-brightness displays with optical bonding for perfect visibility in direct sunlight
All-Weather Durability
IP65-rated protection with vandal-proof design and extreme temperature operation
Industrial Computing
Rockchip, NXP, and STM32 platforms with comprehensive I/O and connectivity options
Application Scenario 1: Electric Vehicle (EV) Charging Stations
The Challenge
EV chargers are public-facing terminals exposed to extreme weather—rain, snow, and intense sunlight. The user interface must be intuitive for non-technical users, responsive in all conditions, and durable enough to withstand potential vandalism. The system needs to reliably process payments and communicate with network management platforms.
The LMTEK Solution
We provide a complete, weather-proof HMI solution. Our all-in-one, IP65-rated HMIs are a perfect fit for rapid deployment. Alternatively, build a custom solution by combining:
High-Brightness (1000+ nits) TFTs with Optical Bonding
Guarantees perfect readability even in direct, bright sunlight
Rugged, Vandal-Proof PCAP Touch Screens
Thick cover glass with all-weather performance (wet finger/glove support)
Versatile SBCs (Rockchip or NXP)
Run user interface, manage charging logic, and handle secure network communications
Application Scenario 2: Solar Inverters & Energy Storage Systems (ESS)
The Challenge
Technicians servicing solar farms and battery storage facilities need a local interface to diagnose issues, monitor performance, and configure settings. These devices are often in sealed, non-ventilated enclosures where internal temperatures can soar. The interface must display complex data clearly and provide reliable control.
The LMTEK Solution
Our components are built for extreme temperatures and data-rich environments.
The Control Core
Our wide-temperature (-30°C to +80°C) SBCs from NXP and STM32 are engineered to operate reliably inside sealed enclosures. They provide essential industrial I/O like CAN bus and RS485 to communicate with the power electronics and sensors.
The Data Interface
Pair the SBC with a cost-effective industrial TFT display and a precise touch screen. This combination gives field technicians a clear, responsive tool for on-site management, reducing service time and improving system uptime.

Application Scenario 3: Smart Grid & Substation Control Panels
The Challenge
Modernizing the grid requires intelligent devices at the substation level for real-time monitoring, fault detection, and remote switching. These control systems must be exceptionally reliable, secure from cyber threats, and have a very long operational life (10-15 years).
The Human-Machine Interface (HMI) must be clear, unambiguous, and dependable for critical operations.
The LMTEK Solution
We provide the stable, long-life foundation for critical infrastructure.
Unmatched Reliability & Longevity
Our NXP-based SBCs are the gold standard for applications demanding long-term stability. We offer a guaranteed 10-year+ lifecycle and strict Product Change Notification (PCN) policies.
Secure & Connected
These SBCs provide the processing power and secure communication interfaces (like Gigabit Ethernet with TSN support) needed to integrate with SCADA systems.
Clarity for Critical Decisions
Combine them with our industrial-grade TFTs to build HMI panels that provide operators with clear, reliable data for safe grid management.

Frequently Asked Questions
What makes a display "sunlight readable"?
It's a combination of two key factors: high brightness (typically over 1000 nits) to overpower ambient light, and optical bonding to eliminate internal reflections, which dramatically boosts contrast and clarity.
Can your touch screens really work in the rain?
Yes. Our advanced PCAP touch controllers use sophisticated algorithms to differentiate between a user's finger and water droplets, ensuring reliable touch input even during wet conditions.
Do you offer solutions that can be powered by DC voltage from a battery system?
Absolutely. Most of our SBCs and HMI solutions support a wide DC voltage input (e.g., 9-36V), making them ideal for direct integration into battery-powered systems like ESS and off-grid applications.
