What began as a local battery maker in Greece has become a global energy tech leader, innovating how the world stores, manages, and uses power. At Sunlight Group, we don't just build batteries, we build the future of energy, driven by our belief in energy for good.
Lithium-ion batteries have become the gold standard for residential solar energy storage, representing over 85% of new installations in 2025. Their superior energy density, long lifespan, and minimal maintenance requirements make them ideal for most homeowners.
Most of our enclosures are designed to NEMA3R and rated for outdoor use. White powder coating and quality manufacturing ensure a robust enclosure that will survive even the harshest conditions.
A 48V LiFePO4 battery requires 16 cells in series, delivering 51. 2V nominal voltage for compatibility with 48V infrastructure. Its advantages in longevity, safety, and efficiency make it superior to lead-acid.
Repairing solar batteries effectively is essential for saving time and money. This guide offers comprehensive steps for troubleshooting common issues such as slow charging and total failure.
Our advanced and innovative equipment enables us to manufacture the best solar battery enclosure as per your requirements. We have specially engineered vents, gaskets, and more.
This project is located in Northern Europe and adopts a large-scale containerized energy storage solution to support utility-scale energy storage and grid stability.
Minimum cabinet height = Rack height (to top of rail) + Battery height + Space above battery (12" ideal) + Charger height + 6" (for space above charger) Chargers need room to breathe and batteries need extra room above for maintenance (watering and testing).
For cost-efficiency, calculate $/kWh/cycle rather than upfront price. Liquid-cooled cabinets typically offer 15% lower lifetime costs despite higher initial investment. Demand transparent cycle life testing reports (≥6,000 cycles at 80% DoD) and validate thermal runaway.
