Frequently Asked Questions

Popular questions about Xinhongye wire

Choosing the right wire size depends on several factors:
  • System current: Generally, you should choose wire that can handle at least 25% more than the system's maximum current
  • Distance between equipment: Longer distances result in more losses, so larger wire should be used
  • Voltage: High-voltage systems require wire with sufficiently high voltage-resistant insulation
  • Installation environment: Outdoor installation should use wire with sun and rain resistant properties
For typical solar systems, we recommend:
  • Connecting solar panels to inverter: Use PV wire 6mm²
  • Connecting battery systems:
    • Small systems (less than 5 kWh): Use 25mm² wire
    • Medium systems (5-10 kWh): Use 35mm² or 50mm² wire
    • Large systems (more than 10 kWh): Use 70mm² wire
Our team is happy to provide consultation to choose the right wire size for your system.

Xinhongye wire is specially designed for outdoor use and has excellent resistance to harsh environments:
  • UV resistant: Insulation contains special additives that resist UV radiation from sunlight, preventing cracking, brittleness, or rapid deterioration
  • High temperature resistant: Can operate at temperatures up to 120°C without deterioration
  • Low temperature resistant: Remains flexible even at temperatures as low as -40°C
  • Water and moisture resistant: Good moisture-proof insulation, suitable for installation in high humidity areas or areas that may contact water
  • Oil and chemical resistant: Insulation is resistant to various oils and chemicals that may be encountered in the working environment
  • Ozone resistant: Does not deteriorate from ozone gas in the air
From testing and actual use in Thailand, Xinhongye wire can withstand Thailand's hot and humid climate excellently and has a lifespan of over 25 years.

PV (Photovoltaic) wire differs from regular wire in several ways, specifically designed for use in solar systems:
  1. Special insulation: PV wire has specially designed insulation that resists UV radiation from sunlight, heat, cold, moisture, and harsh outdoor environments
  2. High operating voltage: PV wire supports high voltages up to 1000V or 1500V, which is higher than regular household wire (220V)
  3. Wide temperature tolerance: Can operate in a wide temperature range from -40°C to 120°C, which is wider than regular wire
  4. Special thick insulation: PV wire insulation is usually thicker than regular wire to better withstand outdoor environments
  5. High flexibility: Designed to be highly flexible, easy to install and route
  6. Halogen-free: Most are manufactured halogen-free, not producing toxic gases when burning
  7. Specific standards: Manufactured according to specific standards for solar systems such as PV1-F, UL, TÜV
Using regular wire instead of PV wire in solar systems may cause the insulation to deteriorate quickly, short circuits, or be dangerous. Therefore, only PV wire that is specifically designed should be used.

Battery cable must be larger than PV wire for the following main reasons:
  1. Higher current: Battery systems have much higher currents than solar systems, especially during peak discharge. Batteries may discharge hundreds of amperes, while solar systems typically have no more than 15-20A per string
  2. Lower voltage: Batteries usually have low voltage (12V, 24V, 48V), requiring high current to get the same power, according to the formula P = V x I
  3. Energy loss: Energy loss in wire is proportional to the square of current (I²R), making systems with high current require large wire to reduce loss
  4. Heat: High current generates more heat in the wire. Large wire helps dissipate heat better
  5. Continuous use: Battery systems must supply power continuously, especially at night or when there is no sunlight
For example, a 48V 5kW battery system may need to discharge up to 104A (5000W ÷ 48V = 104.17A), requiring wire of at least 35mm² or larger, while a solar system with voltage of 600V will have only 8.33A (5000W ÷ 600V = 8.33A), where 6mm² wire is sufficient.

QES Energy can sell Xinhongye wire at a cheaper price than elsewhere due to several factors:
  • Direct import from factory: We import products directly from the manufacturer, not through distributors, reducing costs in this part
  • Order quantity: We import large quantities, getting lower costs
  • Efficient cost management: We have an efficient management system, reducing unnecessary expenses
  • Online sales system: We focus on selling through online channels, reducing the cost of having multiple storefronts
  • Reasonable profit policy: We focus on selling large volumes with reasonable profit per unit rather than focusing on high profit per unit
We intend to deliver quality products at reasonable prices to promote the use of clean energy in Thailand without compromising product quality or standards.
