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.
WE STARTED AS CUSTOMERS
Before Moonday became a manufacturer and energy solutions supplier, we were customers ourselves.
And we encountered a problem.
Products didn't always match what had been promised.
A battery might arrive with different cells, a different BMS or different internal components from those specified during the purchase.
On paper, everything looked right.
Inside the battery, sometimes it wasn't.
And that's a difficult problem for any distributor or installer. You can't open every battery you purchase just to check whether you're getting what you paid for.
We thought there had to be a better way.
So we built one.
Nice to meet you
We're Moonday Energy.
An energy storage company based in China, working with installers, distributors and energy professionals around the world.
We supply battery storage systems, inverters, all-in-one solutions, BESS, solar products and EV charging solutions.
But Moonday didn't actually start with the idea of becoming another energy supplier.
It started because we were customers ourselves.
CLOSE TO WHERE THINGS ARE MADE.
Moonday operates from Guangzhou, at the heart of one of the world's most important manufacturing regions.
Being close to our manufacturing and supply partners allows us to communicate directly, follow production closely and respond quickly when something needs attention.
At the same time, we work with distributors, installers and energy companies across international markets.
Close to production. Close to our partners.
Because a picture says more than words
THE PEOPLE BEHIND MOONDAY
Jirka De Kuyper
Nicolas Serrano R.
Founder and CEO
Founder & International Markets
Different backgrounds. One shared frustration with how complicated sourcing reliable energy products could be.
I came to China 15 years ago for what was supposed to be a three-year project. Three years somehow turned into fifteen.
I fell in love with the country, its energy and its ability to turn ideas into reality. That experience—and everything I learned about manufacturing along the way—eventually helped shape Moonday.
Nicolas came to China for what was supposed to be one year of study. More than 15 years later, he’s still here.
His deep understanding of Chinese culture, combined with a clear sense of what international customers expect, makes him a natural bridge between both worlds.
