The Perfect Retrofit: Why It’s Time to Upgrade Your Off-Grid System

For decades, lead-acid batteries were the standard for off-grid energy. They were dependable, but a new era of efficiency and performance has arrived. The New Use Energy™ (NUE) lithium battery isn’t just a replacement—it's the seamless, high-performance retrofit designed to modernize any existing system. The most compelling reason to switch is a dramatic leap in efficiency. Traditional lead-acid batteries can be up to 20% inefficient during charging, wasting precious solar power. NUE’s lithium batteries boast an efficiency of over 95%, ensuring you capture virtually every watt your panels generate. This means more usable power from your existing solar array and a faster return on investment. Upgrading has never been easier. The NUE lithium battery is engineered to fit the same footprint as a standard Group 8D battery, making it a drop-in replacement for systems using built-in L16s battery boxes. With a weight of just 90 lbs for a 5 kWh unit, installation is simple and allows for an easy upgrade to 15 usable kWh. There are no complex communications to configure; you program it just like a standard lead-acid battery. Our battery has been rigorously tested and is fully compatible with all major off-grid, transformer-based inverter systems, including OutBack Power, Schneider Electric, MidNite Solar, and Sol-Ark. This compatibility guarantees peace of mind and makes it the perfect retrofit for your clients’ systems. NUE’s commitment to resilience is built into every design. The batteries are available in a rugged metal case or an IP67 ABS case for superior protection. For extreme climates, the Heated Battery Option ensures optimum performance down to -40°F. Checking battery status is also simple thanks to Bluetooth communications, which provides easy access to real-time data. Each battery delivers 100A of continuous current (5kW) with a 250A surge, providing ample power for high-demand appliances. With dedicated customer support from licensed installers and employees from leading inverter companies, you have an expert team ready to help you every step of the way.
