PWM Solar Controller 10A20A30A Solar Controller 12V24V USB Photovoltaic Street Light System Controller

1. This charge controller is the ability to automatically identify the system voltage level. This means that the controller will be compatible with a wide range of solar panels and battery systems, allowing for greater flexibility and ease of use.
2. The Automatic Temperature Compensation feature ensures that the controller is able to adjust its charging parameters based on the temperature of the battery system, resulting in optimal performance even in extreme weather conditions.
3. The charge-discharge control parameters are fully adjustable, allowing you to customize the charging and discharging process to suit your specific requirements. This enables you to maximize the lifespan of your battery system and maintain optimal performance.
4. The Battery Low Voltage Disconnection (LVD) feature protects your battery system from damage due to over-discharging, while the overcurrent protection provides an extra layer of safety and ensures that your system is protected from electrical surges and overloads.
5. The Battery reverse connection protection and overcurrent protection features add yet another layer of safety and ensure that your system is protected from damage due to accidental mistakes or electrical faults.
6. Four-stage PWM charging: strong charging, lifting, floating charging, balance;
7. Lithium battery, colloidal, open, and user mode four types of battery charging procedures are optional.
8. The use of liquid crystal display screen design, dynamic display equipment running data, and working state.
9. With real-time electricity statistics function.
10. With battery temperature compensation function.

1:how can we guarantee the quality?

A:  Always a pre-production sample before mass production;

Always final Inspection before shipment;.

2:How can I make sure it's a secure transaction?

A: ****** can protect buyers' interests, all of our transactions will go through the ****** platform. As you do the payment, the money will go directly to the ****** bank account. After we send you the items and you confirm the detailed information, ****** will release the money.

5: I'm very sensible in price, I am a wholesaler of battery packs if I sell your battery pack in my city, the profit is very low, can I get a cheaper price? and I can see your competitor sells cheaper than you.

 A: It is highly suggested that you can have a comparison with our competitor. Indeed, there are also some suppliers that provide low-priced battery packs but use cheap materials. Pls pay attention to the cycle life and the warranty, and we have an anti-vibration design and communication design. maybe you know the price of a cylindrical cell is far low than a prismatic cell. besides, we also provide cylindrical cell solutions, pls contact us directly and we will tell you more. Most Importantly, we can give you a professional solution according to your local market. low profit? Don't worry about that, our engineering team will help you to solve it.
