Q1: What's A PWM solar charge controller ?
A :PWM solar charge controller stands for “Pulse Width Modulation”. These operate by making a connection directly from the solar array to the battery bank. During bulk charging, when there is a continuous connection from the array to the battery bank, the array output voltage is ‘pulled down’ to the battery voltage. As the battery charges, the voltage of the battery rises, so the voltage output of the solar panel rises as well, using more of the solar power as it charges. As a result, you need to make sure you match the nominal voltage of the solar array with the voltage of the battery bank. *Note that when we refer to a 12V solar panel, that means a panel that is designed to work with a 12V battery. The actual voltage of a 12V solar panel, when connected to a load, is close to 18 Vmp (Volts at maximum power). This is because a higher voltage source is required to charge a battery. If the battery and solar panel both started at the same voltage, the battery would not charge.
Q2. May I take some samples to test before placing the order ?
A: Yes, but customers need to pay for the sample fees and express fees, and it will be returned when next order is confirmed.
Q3. What’s the price terms can you offer for us?
A: We can accept EXW, FOB, CIF and so on.
Q4. Where is your main market for your products?
A: Most of our products are exported to Southeast Asia, Europe.PWM Solar Charge Controller China
