Solar Charge Regulator

Solar Charge Regulator

Product name:PWM solar charge controller 30A
Model No.:NC48- 30D
Working principle:PWM Solar Charge Controller is a photovoltaic (PV) charge controller that tracks the PV array to deliver the available current for charging batteries. When charging, the Controller regulates battery voltage and output current based on the amount of energy available from the PV array and state-of-charge of the battery.

Q1:What is a Solar Charge Controller? Why do I need one?

A charge controller, or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged.

Q4. 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.

Q5. What’s the price terms can you offer for us?

A: We can accept EXW, FOB, CIF and so on.

Q6. Where is your main market for your products?

A: Most of our products are exported to Southeast Asia, Europe.
