Battery Energy Storage Systems - BESS
Buy energy when it’s cheapest and store it for peak usage.
Ernest battery systems give you total control over your energy use. Store excess solar during the day or buy low cost off peak power at night, then use it during peak hours, outages, or high demand moments.
With built-in protections and smart monitoring, our batteries provide peace of mind and dependable performance year-round. Whether you’re securing milking operations, keeping hotel guests comfortable, or powering remote pumps, your energy will always be ready when you need it.
Batteries also open the door to future electrification, allowing you to charge EVs, run electric equipment, and reduce diesel dependence across your business.
Solar + Battery
Generate and store energy for peak hours, outages, or high-demand moments.
A combined solar + battery system gives you the best of both worlds – free renewable power during the day and stored energy at night or during outages. This setup ensures your operations keep running, from dairy sheds to commercial kitchens, no matter what’s happening on the grid.
By controlling when and how you use energy, you’ll cut bills, avoid peak charges, and strengthen resilience. You’ll also be positioned for a cleaner, smarter future, with the flexibility to expand as your business or farm electrifies.
With Ernest, your solar and battery system is designed to work seamlessly together. Delivering reliable, farm tough, business ready performance for decades to come.
