The solar junction box is a key component in the photovoltaic power generation system, which is responsible for connecting the circuits of multiple solar panels to form a network of electricity to ensure the smooth flow of electricity from each panel to the inverter. The main functions of this device include preventing local failures, improving power generation efficiency, protecting panels and facilitating maintenance. It has an independent current and voltage signal acquisition function, which can adjust and monitor the current and voltage of each panel in time, so as to improve the power generation efficiency. At the same time, the bus box provides an independent protection function for the photovoltaic cell, when the solar panel overcurrent, overvoltage and other failures, can be cut off in time to avoid damage to the solar panel and inverter and other equipment. In addition, the bus box is usually equipped with current, voltage, temperature and other sensors, which can monitor the working status of each solar panel and transmit the data to the centralized control system in order to detect and repair faults in time. The design of the solar junction box also takes into account lightning protection, with multi-level lightning protection function to ensure that lightning strikes do not affect the normal output of the photovoltaic array

. Its protection level reaches IP65, meets the requirements of outdoor installation, and has remote monitoring function

. Therefore, the solar junction box not only optimizes the system structure, improves reliability and maintainability, but also enhances the safety and stability of the photovoltaic system

FAQ

A. Are your inverters pure sine wave output?

Q: A Yes, All are true pure sine wave.

A: What kind of output you can do?
Q: Normally we produce inverter with 110V 115V 120V 220V 230V 240V, 50/60Hz self-adaption. If you have special requirements, please tell us for engineer consulting.

A: What' s the difference between low frequency and high frequency inverter?

Q: Low frequency inverter has various protections, strong ability to adapt to the environment. more reliable, with voltage regulation.

A: What's the difference between pure sine wave inverter and modified sine wave inverter?
Q: Pure sine wave output inverter is just as good as the Public power grid. Even better. Low repaired rate, long lifespan, Without harmonic pollution, enviromental-friendly and appliances protected.
Modified sine wave output has a negative impact on appliances and can't load inductive load, such as air contition, refrigerator and etc. Certain motor control circuits don't like the modified wave.

A: What appliances your inverters can load?
Q: Our inverter can be used in household, Office, agricultural appliances and other inductive load such as refrigerator, air conditioner, water pump, etc.

A: Can you print our company logo on inverters, nameplates and packaging?
Q: Yes, we accept OEM orders.

A: How to choose a right inverter?
Q: Tell us your demand, then our sales will recommend a suitable inverter to you.

A: How to solve the technical problem?
Q: 24 hours after-service consultancy just for you and to make your problem to solveeasily.

A: Do I Need A Power Inverter?
Q: Actually, no. This is the only component of a solar energy system that is not absolutely required. However, if you don't use one, you will not have 220 or 230 volts AC and will have use battery power alone. This might be acceptable in a small RV or cabin, but most people want to use normal AC appliances.

A: What's The Difference Between 12, 24, And 48 Volt Inverters?
Q: This refers to the input voltage from the battery bank. The main consideration is that at higher voltages the current is less so that you can use smaller wires between your solar panel array and your battery bank. Of course, when you decide on a system voltage, the Solar Panels, Inverter, and Battery Bank all need to use the same voltage.

A: What to do if the product is broken?
Q: If any product is faulty, you can send the picture or video to us, we sill study it and supply the spare parts of PCB board free for after sale service.
