How to connect the controller with WiFi networking IOT mode?

The phenomenon that the load end of the controller cannot work normally and the handling methodThe system is connected normally, the controller shows normal charging, but there is no load discharge arrow icon, and the load bulb does not light up

Over-current protection phenomenon and solution

How to choose your right controller for your solar system-1How to choose PWM and MPPT controllerWhen choosing and using solar controllersDo you have any doubts as follows1.When choosing a solar controller, I don't know how to choose the right controller to match your solar panel.2.I don't know how to choose the suitable system voltage.3.When choosing MPPT controller, I do not know how the solar panels are connected in series or in parallel to ensure the maximum input voltage range allowed by the controller

From the previous explanation, we know that if We choose MPPT solar controller, the voltage of solar panel can not match with battery and controller ,that is to say the voltage of solar panel can be higher than the battery voltage, but cannot exceed the maximum input voltage Voc of the selected MPPT controller.

Battery overvoltage protectionThe controller is now in overvoltage protection stateThe battery is full and the warning sign flashes

Check the LCD screen, the warning icon and temperature icon flashPress the up key/menu key to come to the temperature display interfaceCheck that the current controller temperature is 83°,more than 75°Means that the controller is now over-temperature protected

Low voltage protection phenomenon and solutions

Land Dream E Series (LD-E in short) is an economical and PWM solar controller. it can not only extend the service life of battery,but also provide necessary protection over the whole system. We own its outlook design patent. The double buttons and LCD screen show you the working parameters of the whole system,clear and understandable. This series is widely applied in small solar home system.

Tracer Dream S Series adopts MPPT technology. It's also ran by 32 bits CPU,so stability and speed can be guaranteed. Based on the synchronous rectifier technology.the transfer efficiency of circuit can be increased up to 98% and the Pmax tracking accuracy up to 99.5%.So our MPPT can trace the accurate Pmax inthe shortest time (10~20s),even when the sunlight changes rapidly. It can perfectly handle extreme weather or weak sunlight.

The GD series inteligent active battery balancer automatically detects the battery voltage during the charging and dischargingprocess, adopts a bidirectional energy transfer balance, and transfers the energy ofthe high voltage battery to the low voltagebattery through energy transfer, thereby achieving equal voltage between the two batteries. High conversion eficiency and fastspeed to achieve balance. The working mode and balance parameters can be set through the meny, which is suitable for variousapplication scenarios of customers.

Tracer Dream F Series controller is based on Multi phase synchronous rectification technology and advanced MPPT controlalgorithm, adopt co-negative design, with LcD displaving running status, The MPpT control algorithm can minimize themaximum power point loss rate and loss time, quickly track the maximum power point of the PV array and obtain the maximumenergy from solar modules under any conditions; and can increase the ratio of energy utilization in the solar system by 20%-30% compared with a PWM charging method.
