Company Profile

 

Q1: Are you a trading company or a manufacturer?

We are Integration of industry and trade, our company has a history of 40 years. We have been specializing in the production of a series of photovoltaic electrical products, such as circuit breaker, pv combiner boxes, pv connector, surge protector, pv fuses, pv tool accessories and etc.

Q2: If OEM is acceptable?

We can provide OEM and ODM services. We have many different specifications and appearances for customers to choose.

Q3: Do you provide sample? Free or charge?

We can provide free samples to customers, but only one piece, but customers need to bear the freight. For some special products, we also offer free samples. Considering their particularity, we usually refund the sample fees to customers after they place formal orders.

Q4: How long is your delivery time?

Our delivery time is determined according to the purchase quantity. Generally, it is about 3-40 days, less than 300 pieces within 5 days, 300-2000 pieces within 7-15 days, 2000-20000 only within 15-40 days.

Q5: How is the weather resistance of the distribution box? Can it be used outdoors for a long time?

It adopts UV stabilizer + PC/ABS composite material. Through ISO4892-2 ultraviolet aging test, the outdoor service life is ≥ 10 years. An optional UV-resistant coating can further enhance the weather resistance.

Q6: Does it support DC photovoltaic applications?

The entire series supports the DC1500V system. It is equipped with an internal slot for islanding protection and has passed the TUV photovoltaic-specific certification.

Q7: What are the specific test conditions for the IP65 protection level?

According to the IEC60529 standard, IP65 indicates complete dust-proof (level 6) and water-resistant (level 5). It means that it can resist low-pressure water jets (with a nozzle diameter of 12.5mm and a flow rate of 30L/min).

Q8: Is there a pre-installed cable hole in the box? What is the range of the hole diameter?

The standard configuration includes 6 detachable knock-down holes with diameters ranging from Φ20 to Φ50 mm (position adjustable), and additional waterproof cable connectors can be installed (optional).

Q9: What are the installation specifications for DIN rails?

Standard configuration is 35mm standard rails (EN60715), compatible with all modular circuit breakers/surge protectors. Special requirements can be customized with 15mm or 75mm rails.

Q10: What about the material and pressure-bearing capacity of the transparent window?

It is made of 5mm thick impact-resistant polycarbonate (transmittance ≥ 92%), which can withstand 50J mechanical impact.
