An improper sequence order can damage the controller!
Emergency Announcement:
At present, some sellers like E***N, they sell the similar 40A 50A 60A controllers with very low price,but their
fake 40A 50A 60A are very light and have no heat dissipating teeth on the bottom. they are not real 40A 50A
60A.You can do the test if you already bought them ! Please don't buy their cheaper controllers to save money
If you don't believe it, you can buy our controllers and their controllers for comparison!
Package Includes:
1 x 20A 12V/24V Auto PWM Solar Charge Controller. CityTech BD
