Contact Us / Request a Datasheet
One line: Send the model number and destination market — you get specifications, the matching certification files and a quotation, not a generic brochure.
What to send us
To quote accurately, we need four things:
- Model numbers you are evaluating (e.g.
HE200-7200-F,HE300-12000-F,HE310-5000-F) — or describe the load and we will suggest models. - Quantity per model and order frequency.
- Destination market / country — this determines which certification files apply and whether the model can be shipped there.
- Application — residential backup, commercial site, irrigation, standby for a workshop, etc.
What we will send back

Role: supplier and exporter of solar inverters and LiFePO4 energy-storage systems.
Which channel to use: WhatsApp for anything time-sensitive — model check, stock, lead time. Email for datasheets, certificate files and quotations, so that you have a written record you can forward internally.
Contact address: the address above is where we receive correspondence and where goods are handed over for export. Buyers who want to verify the entity record can check the Unified Social Credit Code on China's National Enterprise Credit Information Publicity System.
Before you send
Two things worth knowing:
- Certification is model-specific. A CE certificate covering HE200-7200-F does not cover an I5 (IP54) variant or a HE300 model. Tell us the exact model and we send the right file. Full list on the certifications page.
- Battery models currently have no UN38.3 report. This restricts air and sea transport for lithium battery products. Ask before planning logistics.
