常见问题

Do you offer bulk or wholesale orders?

We need 500 units of custom 48V to 12V 50A converters with special waterproof connectors for our fleet. Can you customize this?

A: Yes, absolutely! Daygreen provides extensive OEM and ODM custom engineering services for bulk orders. Please email your technical specifications, required connector type, quantity, and destination to sales@daygreen.com. Our engineering team will review your requirements and provide a custom proposal and quote promptly.

Can I connect two of your 12V to 24V converters in parallel to double the output current?

A: No, our standard DC-DC converters cannot be connected in parallel for output current expansion unless specifically designed with active current sharing. Instead, we recommend selecting a single higher-amperage model (such as our 50A or 60A models) that meets your total load requirement safely.

Where is my order, and how long does shipping to Europe take?

A: You can track your order directly in this chat by selecting 'Track my order' and entering your order number and email. For European destinations, standard delivery usually takes 7-15 business days depending on carrier and customs clearance. Once dispatched, tracking updates are automatically emailed to you.

What is your warranty policy if the converter fails during installation?

A: Daygreen stands behind our products with a comprehensive warranty against manufacturing defects, alongside a 30-day return policy for unused items in original packaging. If you encounter any technical issues, please contact our technical support at sales@daygreen.com with your order number and wiring photos for immediate diagnosis or replacement assistance.
