Hardware is the foundation of product performance. To improve the core performance and operational stability of the OD series PWM solar controllers, LDSOLAR has carried out a major upgrade to the product's core hardware, upgrading the chip from the original 32-pin to 48-pin, and canceling the display driver chip at the same time.

To meet users' needs for remote monitoring and intelligent connection of solar controllers, LSOLAR has upgraded its OD series PWM solar controllers by adding an optional RJ45 interface function. Users can choose to match with external WiFi/Bluetooth modules according to their needs (Note: After selecting the RJ45 interface, a pair of USB interfaces will be reduced).

More Convenient Data Management! OD Series Solar Controllers Support 60-Day Power Generation Statistics, Requiring Matching APP for Use

To improve the intelligence level of solar controllers and better adapt to the work needs under different lighting environments, LDSOLAR has upgraded its OD series PWM solar controllers by adding a light control recognition voltage setting function, realizing flexible adaptation of the light control function.

To enrich employees' cultural life and enhance team cohesion, LDSOLAR organized a three-day team building trip to Luoyang, Henan Province, from October 31 to November 2, 2025. Centered around the theme "Ancient Capital Luoyang & Sacred Laojun Mountain," the activity successfully combined natural scenery, historical culture, and team bonding.

Lead-acid batteries are widely used in solar systems, and the stability of their system voltage is crucial to battery performance and service life. To solve the problem of voltage fluctuation that may occur during the use of lead-acid batteries, LDSOLAR has upgraded its OD series PWM solar controllers by adding a lead-acid battery system voltage lock function.

As a common energy storage device in solar systems, lithium batteries' charging effect is directly related to battery life and the overall performance of the system. LDSOLAR is well aware of the importance of lithium battery charging technology. Recently, it has fully optimized the lithium battery charging algorithm of the OD series PWM solar controllers, realizing the function of controlling charging termination through current, which greatly improves the safety and effectiveness of lithium battery charging.

During the use of solar controllers, the adaptation of baud rate directly affects the communication efficiency between the equipment and other systems. To meet the personalized needs of different users in baud rate selection, Wuhan Welead New Energy Co., Ltd. has upgraded its OD series PWM solar controllers by adding a baud rate interface, allowing users to select the baud rate according to their actual needs.

Recently, Wuhan Welead New Energy Co., Ltd. announced a major upgrade to its OD series PWM solar controllers. Among them, the highly concerned models OD2410C, OD2420C, and D2430C have been officially upgraded to OD2410S, OD2420S, and D2430SE, with the core highlight being the addition of a practical current display function.

As we embrace the golden autumn, with osmanthus blossoms filling the air, we are delighted to celebrate the coinciding National Day and Mid-Autumn Festival. The entire team at LDSOLAR extends our warmest greetings and heartfelt gratitude for your continued trust and partnership.

Not only the product itself, but also the packaging design of the TD2106 MPPT solar controller has poured the team's care. Every detail from transportation protection to environmental protection concept shows the brand's ultimate pursuit of user experience.
