VS-AU Series(10~60A) PWM Charge Controller
With LCD display and two USB ports
VS-AU series is a PWM charge controller with LCD display and two USB ports. When the gap between solar panel working voltage and battery voltage is not big, choosing this PWM series is an equally reliable but more cost-effective solution. It is widely applied to rural Electrification and home power systems etc.,

Product Highlights
Series PWM charging mode
Full power working at working temperature range
Multiple load control modes
Adopt high quality, high-reliability international brand components
Double USB design
Segment LCD display design
Real time energy statistics function
Extensive electronic protection
The two USB ports are paralleled, the total power is 2.4A/5V, so it is 2.4A/5V too if the only USB port is used. If overloaded, there will be over current protection or even damage to the controller.

Hi
How can I set the limit for discharge voltage?
It stopped at 11.3 volt, I want it to go to 9.9 in 3s 33 p battery pack of lithium ion battery

Thanks for reaching us! Vs-au is a PWM controller, which cannot be connected to a lithium battery. At the same time, this controller can only select the battery type and cannot change parameters

Epever PWM VS-AU6024 what the max solar panel Wp can be install?
mason@epever.com –
Hi Bakti, thanks for reaching us. If your battery voltage is A, then A x 60A would be the max solar panel Wp in this case.

Hi.
I have a VS4548AU controller.
before to conect the PV system, the voltage is 35V.
When i conect the PC to the controller, the PV voltage show 12V.
The battery charge doesnt hapens.

Hi. Can this device be linked to your smartphone via Bluetooth?
chenyaohua@epever.com –
Hello sir, the VS-AU can’t be linked to smartphones via Bluetooth, since it doesn’t have a com port.
