Solar Junction Box Specification

Solar Project Capacity

Solar energy can reduce electricity bills

• Generating your own power: generate electricity from sunlight, reducing your reliance on the power grid
• Government incentives: Government incentives can help reduce the initial investment
• Net metering: With a net metering system, you can sell any surplus energy
• Protecting against price fluctuations: Solar energy can help protect your budget from unpredictable power price fluctuations.
• Save Money on Electricity Bills: you can cut down on how much you rely on regular electricity from the grid

Solar array junction box (AJB)

A solar array junction box (AJB) is a vital component of a solar power plant that serves several purposes. They're also known as PV combiner boxes.

Solar array junction box (AJB) is a vital component

Combines multiple strings: AJBs combine multiple strings of solar panels into a single string, reducing the number of wires needed.

Protects the inverter: AJBs protect the inverter from damage caused by fluctuations in the output from the solar panels.

Grounds surges: AJBs prevent sudden surges caused by lightning strikes during cloudy or rainy conditions and immediately ground the surges.

Choosing a solar array junction box:

• They combine the DC voltage from multiple solar panels into a single array output.
• They block reverse current from flowing from the battery to the solar panels at night or when there's low radiation.
• They can be made from materials like thermoplastic (ABS) or polycarbonate.
• The junction box should have features like fuses or MCBs for overload protection, and a surge protection device (SPD) to protect against lightning and electrical surges.
• The IP rating indicates how well the junction box protects against dust and water. A higher IP rating is better for harsh environments.
