Pv Controller

Pv Controller

Product name:PWM solar charge controller 40A
Model No.:CL12/24- 40DU
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.

About 40 amps pv solar charge controller

1. Intuitionistic LED indicators show the system battery capacity,charging and discharging state of battery.

2. Having the protection functions as over charging,over discharging ,overload,short circuit and reversed connection.

3. Tandem type PWM charging makes the charging efficiency increase by 3% to 6%,compared with non-PWM charging.

4. The parameters of charging and discharging have been set during the production(special parameters need to be told in advance),so no need to adjust the parameters.

5. You can set the working mode of the load.

6. Prevent battery from discharging to battery at night.

FAQ

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.

Q2:Do I always need a charge controller?

Not always, but usually. Generally, there is no need for a charge controller with the small maintenance, or trickle charge panels, such as the 1 to 5 watt panels. A rough rule is that if the panel puts out about 2 watts or less for each 50 battery amp-hours, then you don't need one. 

4 Q:What kind of payment do you accept?

A:We accept T/T, Paypal, Western Union for samples order.

5. Q:What kind of controller you mainly manufacturer?

A:We mainly produce PWM solar charge controller, MPPT solar charge controller.

6 Q:Can we print our company logo on product and package?

7 A:Yes,but quantity of order is required. And we also need you to offer the Trademark authorization to us.
