12/24V 50A PWM Solar Charge Regulator for RV Camper, Yacht Marine and Off-Grid Battery System-1

The PWM solar controller is used to control the photovoltaic panel to charge the battery. Adopt PWM charging mode. Compared with the ordinary solar controller, the charging speed is faster, the safety performance is higher, the charging conversion efficiency is 75 ~ 80%. It has the function of protecting the battery from overcharging and overdischarging.

• 12v/24v voltage automatic identification system.
• Athree-stage charging PWM algorithm, discharge or timing to an equalizing charge of battery.
• Prevent battery imbalance and sulfide phenomenon, improve the service life of the battery.
• Using temperature compensation, automatic adjust charging parameters.
• Rich load working mode, easy to use in all kinds of dc load.
• Have overcharge, discharge protection, overload protection, and electronic short circuit protection.
• Load using advanced methods, can start the large capacitive load.
• Use graphic dot-matrix LCD, and key man-machine interface operation.
• Browsing, dynamic interface humanization design, convenient intuitive operation.
• Level of industrial design, can be used in all kinds of bad environment.
• TVS lightning protection.

Relevant Information

During this period, the industry concentration was relatively low, with a large number of small workshop‑style manufacturers. Product quality was uneven due to the lack of unified standards and specifications. Some low‑cost products even omitted over‑temperature and lightning protection functions, causing frequent system failures. Nevertheless, this technological breakthrough drove photovoltaic systems from “usable” to “practical” and promoted the popularization of off‑grid PV systems, especially in rural and remote mountainous areas to solve electricity shortages.
