FAQs

Are you a factory?

No, we’re a brand that works exclusively with one factory where we hold technical shares. The factory focuses on production; we focus on everything else — quality control, order management, logistics, and long-term support. This gives you factory-direct consistency with brand-level accountability.

What types of solar products do you offer?

We supply inverters, energy storage battery packs, all-in-one energy storage systems, and full kits of solar panels + inverters + battery packs. Contact us to request a quote for your specific setup.

How does you ensure product quality?

We ensure quality at every stage:

  • Rigorous testing – Each unit undergoes 100% factory testing before shipment

  • International certifications – CE, RoHS, MSDS, UN38.3, and STA Report

  • Warranty –5 years standard warranty with technical support

This guarantees long-term, stable performance.

What is your production capacity?

We maintain ready stock for immediate delivery and have flexible production capacity to handle large rush orders. For specific volume inquiries, please contact us with your requirements.

Can you guarantee on-time delivery?

We will evaluate delivery feasibility based on your order and production schedule, and only make commitments we can keep. Once we commit, we fully honor it.

Do you support OEM or customized solutions?

We offer ODM/OEM services, but for custom work on electrical architectures, intelligent strategies, and underlying processes, we’ll need to assess your requirements first to determine feasibility.
