Q1: Are you a factory?
A: Yes, we are the top 10 power supply manufacturers in China, with over 7000 square meters production area. We focus on inverters, solar panel regulators, solar generators and solar power system solution. We cooperate with some famous brands all over the world, can provide customized production or add your logo on products.

Q2: What is the function of solar panel regulator?
A: Solar panel regulator is the core control part of solar panel system. It is an automatic control equipment that controls the multi-channel solar panels to charge the batteries and the batteries to supply power to the load by solar inverter.

Q3: How much is solar panel regulator?
A: Tell me your requirements, such as regulator types mppt or pwm, voltage, charging current, quantity, and whether there are other functional requirements. We will give you the most favorable ex factory price. Solar panel regulator factory direct sales, no middlemen earn price difference.

Q4: MPPT or PWM, Which solar panel regulator is better?
A: There are two main types of solar panel regulators on the market: MPPT and PWM. MPPT solar panel regulator is suitable for solar panel system greater than 2kW. Because of its powerful function, it can save you whole set solar system costs by reducing other costs. PWM solar panel regulator is suitable for small-scale solar panel system which does not need many functions and has a small budget, PWM is very cost-effective. Don't know how to choose PWM or MPPT, contact XINDUN.

Q5: How to solve the solar panel regulator technical problem?
A: We will provide market and product training services, 24 hours after-service consultancy just for you and to make your problem to solveeasily.
