In the rapidly evolving landscape of renewable energy and portable power, technical compliance is not merely a legal hurdle—it is a hallmark of engineering excellence. As a leading exporter, Suzhou Maili Electrical Appliance Co., Ltd. (Pass Power) integrates stringent global standards into the very architecture of our pure sine wave inverters and battery chargers.
Our CE certification ensures that every unit—from our 500W converters to 20kVA industrial inverters—meets health, safety, and environmental protection standards for the European Economic Area. Coupled with ROHS (Restriction of Hazardous Substances), we guarantee that our PCBs are free from lead, mercury, and cadmium, promoting a sustainable electronics lifecycle.
For our partners in Oceania, SAA certification is critical. We provide customized power solutions that adhere to AS/NZS standards, ensuring that our equipment survives the harsh Australian climate while maintaining grid stability in caravan and off-grid solar applications.
Suzhou Maili Electrical Appliance Co., Ltd. is a professional manufacturer and exporter in the field of power inverters, battery chargers, and power supplies for more than 13 years. Established in 2012 and certified as a high-tech enterprise, our facility covers 2,770 square meters with two advanced production lines. We have built a comprehensive quality control system and hold international certifications including CE, ROHS, IP30, and SGS.
We are not just following trends; we are setting them. Our technical trajectory focuses on efficiency, intelligence, and integration.
Implementing Gallium Nitride (GaN) transistors to reduce heat and increase efficiency by 15%.
Inverters with integrated AI for predictive maintenance and load balancing.
Bidirectional chargers enabling Vehicle-to-Home energy transfer for smart grids.
Exploring solid-state conversion technologies for ultra-compact power density.
From PCB SMT assembly to transformer winding, we control the entire process to ensure quality and reduce lead times.
Our two production lines can pivot between small-batch OEM and large-scale wholesale production within 48 hours.
Located in Suzhou, we leverage proximity to the Port of Shanghai for rapid global shipping and reduced carbon footprint.

Custom colors, logos, and industrial design chassis.
Universal, UK, EU, US, and AU socket configurations.
"I have bought 4 of these inverters and the build quality and performance is excellent. Still working well after 5 years. Easy to talk to and supportive."
- Mark Augustin, United States"I have purchased many times and am very satisfied with their product quality and after-sales service."
- Sergey Sukhotskiy, KazakhstanPure sine wave inverters provide high-quality electricity, similar to the grid, which is essential for sensitive electronics like medical devices, lasers, and appliances with AC motors. Modified sine wave inverters can cause overheating and noise in these devices.
This depends on your battery bank. Larger systems (over 3000W) typically use 48V to reduce current flow, allowing for thinner cables and higher efficiency.
Yes, we offer specialized ODM 3-stage chargers specifically programmed for Lead-Acid, AGM, and Lithium (LiFePO4) battery chemistries.
Our 3-phase units (like the 20kVA model) provide balanced power output for heavy machinery and can be integrated into high-frequency industrial grids with CE/CB certification.
