PWM Controllers
High-Voltage PWM Digital Solar Controller 96V-614V – Top China Suppliers & Factory Solutions
This advanced PWM digital solar controller, available from reputable China suppliers and manufactured in our state-of-the-art factory, caters to a range of voltage specifications including 96V, 144V, 240V, 360V, 537V, and 614V. Designed to precisely manage the charging process from photovoltaic panels to batteries, this controller is an essential intelligent housekeeper for high-voltage photovoltaic systems, ensuring optimal performance and reliability
Description
It adopts the highly efficient PWM charging mode, which can dynamically adjust the charging current and voltage according to the real-time status of the battery, making the charging process more scientific and reasonable. It has a very wide voltage input range, which can automatically adapt to the voltage changes under different lighting conditions, and can work stably in both sunny days and cloudy days.
In terms of battery protection, it performs well and can effectively prevent the battery from overcharging and over-discharging. Overcharging will damage the internal structure of the battery and shorten its service life; over-discharging will cause the battery capacity to drop. This controller can accurately control and improve the charging efficiency, so that more solar energy can be converted into electricity and stored. At the same time, it provides reliable protection for all kinds of photovoltaic power supply systems, ensuring stable operation in complex environments and greatly extending the service life of the battery and the entire photovoltaic system.

Frequently Asked Questions
Q
What is PWM charging mode and why is it beneficial for solar systems?
PWM (Pulse Width Modulation) charging mode dynamically adjusts the charging current and voltage based on the real-time status of the battery. This makes the charging process more scientific and efficient, helping to maximize the amount of solar energy converted and stored while protecting battery health.
Q
What system voltages does this PWM controller support?
This controller supports a wide range of system voltages including 96V, 144V, 216V, 240V, 360V, 480V, and 600V, making it compatible with various small and medium-sized off-grid solar power systems.
Q
How does the controller protect the battery from damage?
The controller provides multiple layers of battery protection, including overcharge protection (which prevents damage to the battery’s internal structure) and over-discharge protection (which prevents capacity loss). These features significantly extend the service life of the battery and the entire photovoltaic system.
Q
Can this controller operate in extreme outdoor environments?
Yes. The controller is designed for environmental adaptability and can operate within a temperature range of -20℃ to +70℃. It also features PV array reverse connection protection and night-time anti-reverse charging, making it well-suited for complex outdoor environments.
Q
Does this controller support communication interfaces for remote monitoring?
Yes. The controller optionally supports data communication functions including RS-485 interface and MODBUS communication protocol. This makes it suitable for distributed power supply scenarios such as communication base stations and street light monitoring systems.
Q
Is this controller suitable for cost-sensitive solar projects?
Absolutely. The controller is designed with digital technology for fully automatic operation and a simple control strategy, keeping costs low. It is an ideal solution for low-cost PV power generation scenarios where extreme efficiency is not the primary requirement but reliable, stable operation is essential.
