Intelligent 20A 12V/24V Solar Charge Controller Metal Case Auto-ID PWM Regulator Time-Control Solar Power Panel Battery Lamp Light-Control Overload Protection


Stock 0
The product is the new generation of intelligent solar charge and discharge controller, it has strong stability and high service life. This series is 12V/24V automatic identification, with automatic detection battery voltage function, PWM charging way and comprehensive protection function: overcharge, over-discharge, over-current, short-circuit, reversed. Custom design about adjustable control parameters is accepted.

The solar controller has household type and street lamp type in the design of an organic whole.
The solar controller has 12V, 24V auto identification of the design.
The solar controller has light control and time control (street lamp type).
The solar controller has the overcharge, discharge, over current, short circuit, answer back and protective measures.
The solar controller has the power-down protection, it means the controller can auto save the parameters we set before when there no power.
With the Strong charging and equilibrium charging, floating three-step PWM control charging ways.
CE and RoHS certificated to offer safer and reliable use.

Note: if the 24V battery loss bad, voltage is less than 17V, connected to the controller may recognition for 12V system. (such as the discovery of battery under-voltage, controller still output normal, need to change battery).

Safety Advice:
1.The controller has reverse connection protection, but still it is strictly prohibited to pick back, and then against load there is some damage.
2.Joint battery found controller doesn't work properly or doesn't work, must be timely inspection line, not allowed at the moment it is to pick up panels (panels and battery at the same time meet back and may damage the controller).
3.Battery has lots of energy, it should avoid battery accident short circuit at any time.
