Nice to meet you

Moonday Energy was founded with a simple mission: bringing transparency, quality, and trust back to the energy storage industry.

Before becoming a manufacturer and supplier, we were customers ourselves. During our search for reliable energy storage solutions, we discovered that products delivered by some suppliers did not always match the specifications that had been promised. The battery cells, BMS, and internal components were sometimes different from what was stated on paper.

This experience highlighted a major challenge within the industry: customers cannot easily verify what is inside every battery system they purchase.

Rather than accepting this reality, we decided to build a better solution.

By combining our own manufacturing capabilities with carefully controlled sourcing, we maintain full visibility throughout the entire supply chain. Every component is selected according to strict quality standards, and we work exclusively with Grade A battery cells to ensure safety, reliability, and long-term performance.

Today, Moonday Energy provides complete energy solutions, including battery storage systems, inverters, all-in-one systems, solar panels, BESS solutions, EV charging stations, and portable power stations.

Our commitment remains unchanged: deliver exactly what we promise and build long-term partnerships based on trust, transparency, and quality.

Moonday Energy specializes in advanced lithium battery and energy storage solutions for residential, commercial, and industrial applications. Our product portfolio includes home energy storage systems, all-in-one ESS solutions, commercial battery storage systems, and utility-scale energy storage solutions designed to support a more reliable and sustainable energy future.

Operating globally from China, we work closely with customers, distributors, installers, and project developers to deliver high-quality energy storage products backed by technical expertise and responsive support. We collaborate with trusted manufacturing partners and maintain strict quality and compliance standards to ensure reliable performance and long-term value.

At Moonday Energy, we are more than a supplier—we are a partner committed to helping our customers achieve energy independence, improve efficiency, and successfully deploy energy storage solutions worldwide.

Say hello to Biaspark, our bright and joyful firefly mascot. More than just a symbol of light, Bia carries a deeper meaning rooted in ancient Greek mythology. Her name comes from Bia, the goddess of strength, determination, and inner power, who stood beside the great forces that shaped the world. Inspired by this mythological origin, Biaspark represents the spark that guides progress — a small but powerful light that leads the way forward. With her glowing presence, she reminds us that even the tiniest spark can inspire movement, clarity, and new beginnings.
