Here’s everything you need to know.
Who Is Sigenergy?
Sigenergy is a clean energy company that makes solar batteries, inverters, and energy management systems. It was founded in 2022 by a group of experienced engineers and executives from the solar and battery industry. Many of them came from other well-known energy companies.
Even though the brand is new, the people behind it are not.
Sigenergy focuses on products for homes and small businesses. Their signature product is the SigenStor, which combines a battery, inverter, and EV charger in one unit. The design is sleek, modular, and innovative. The company also makes a mobile app that helps you monitor and control your energy use.

Where Are Sigenergy Batteries Made?
Sigenergy batteries are made in China. The company designs, engineers, and manufactures its products at its own advanced facilities in the country. While some people might feel unsure about products made in China, the story is more complex. Quality depends on how a product is made, not where it is made.
Having their own factory matters. Some brands outsource manufacturing to third parties. Sigenergy does not. This helps them manage quality, reduce errors, and scale production more efficiently.
Sigenergy is a relatively new company, but it boasts deep experience behind it and offers batteries that meet international safety and performance standards. It also backs its products with a 10-year warranty.
Their headquarters are also in China, which allows them to keep product development and manufacturing close together.

What Does ‘Made in China’ Really Mean for Solar Batteries?
Many solar batteries on the market today are made in China. That includes parts or entire systems from some of the biggest names in the industry. China is home to most of the world’s battery supply chain. It produces the raw materials, battery cells, and many of the control systems used in energy storage.
The phrase “Made in China” does not mean lower quality. What matters more is who is making the product and how well it is designed and tested.
In Sigenergy’s case, the company meets several international certifications and performance benchmarks that are used worldwide. If a battery meets these standards, it has passed rigorous quality checks.
Sigenergy also works with partners in Europe, Australia, and the United States to make sure its products meet local market needs. This includes compliance with regional grid rules and connection standards.

Are Sigenergy Batteries Safe and Reliable?
Yes, Sigenergy batteries are designed to be safe and reliable. The SigenStor system includes multiple safety features, such as:
- Fire-resistant battery cells.
- Real-time thermal monitoring.
- Overvoltage and short circuit protection.
- Remote firmware updates.
The battery utilises LFP (lithium iron phosphate) chemistry, recognised for its high safety and extended lifespan. This type of battery is less likely to overheat and is more stable during daily use.
Sigenergy offers a 10-year warranty, which is standard in the industry. This warranty covers defects in materials or workmanship. It makes sure that the battery will retain at least 70% of its usable capacity after 10 years of everyday use.
Although the company is still relatively new, early reports from installers and distributors indicate that the product performs well and is easy to install. The modular design allows for flexibility in different system sizes, and the mobile app provides users with more control over how they use and store power.

How Do Sigenergy Batteries Compare to Tesla and Enphase?
If you’re comparing Sigenergy to better-known brands like Tesla Powerwall and Enphase IQ Battery, here’s what you should know.
Where They’re Made:
- Sigenergy: Made in China, in a company-owned factory.
- Tesla Powerwall: Assembled in the United States, with battery cells from various global suppliers, including China.
- Enphase Battery: Made in the United States with some parts sourced from China.
Reliability and Safety:
- All three brands use lithium iron phosphate battery chemistry.
- All offer real-time monitoring and built-in safety controls.
- All have passed major international safety certifications.
Warranty and Support:
- Sigenergy: 10-year warranty with 70% capacity retention.
- Tesla Powerwall: 10-year warranty with 70% capacity retention.
- Enphase Battery: 15-year warranty with 60% capacity retention.
Sigenergy holds up well on paper, but it has not been in the market as long as Tesla or Enphase. Tesla and Enphase have more field data and larger installer networks. Sigenergy is still building those relationships in different countries.
