SunReadFarm EV solar charger

Solar voltage stabilized direct charge uninterrupted, battery synchronous pressure measurement controller


SunReadFarm Technology Co., Ltd established in 2018, is located in Taichung City, Taiwan.
Our company focuses on the R&D, production and sales of controllers for solar regulated charging. A new-architecture solar controller is very suitable for outdoor use of cars .

1. Simple BMS Controller for Solar Stabilized Charging.
2.The battery can be charged up to a single solar voltage regulator. Multiple battery voltage points can be set to control the     voltage.
3.Solar energy stabilized direct charge is uninterrupted, the battery voltage is detected synchronously, the 
   charge reaches the specified battery voltage value, and the charge is stopped.
4.Normal battery voltage, battery full voltage. The battery is charged only when the power consumption
   drops at the specified voltage point, and the charging is safer.
5.The controller charging method is fast charging mode.The maximum current power supply when charging.
6. Suitable for lithium batteries, lead-acid batteries, etc. Can be used for  car charging generator backup.
7.100% priority is given to using solar energy.


Applied to lithium battery:          maximum chargeable voltage when connected in series = 4.2 X N
                                                                                                       Normal voltage can be set = 3.7 X N
                   When the normal battery voltage drops, the maximum current power supply when charging.
                 Multiple battery voltage points can be set.reaches the specified voltage value, the charging will stop.
                                                                                                       battery full charge stop set=4.2X N -0.1Vtg
                     Solar charging current / lithium battery rechargeable current = 0.1 ~ 0.9 (small value, high safety)

       Equipped with self-developed remote battery voltage detection technology, the controller can synchronize the battery voltage when the voltage is regulated and directly charged. Supports wires up to five meters in length, and the battery can accurately control the voltage to the second decimal place.

Battery two step protection :
  1. Charge the battery not to exceed the chargeable charging voltage, and the battery will not overvoltage.
  2. Charge only when the normal battery voltage is drained
  3. The battery is never under pressure.Therefore, it can reduce the battery DoD and increase the temperature of the battery after high current output. Prolong battery life.Increase the running distance of the equipment.
This product has passed Ce FCc electronic product safety certification. Simply connect the positive and negative two power lines of the solar panel to the controller, and after converting to a suitable voltage, connect the positive and negative two wires to the battery of the mobile device. . Easy to install.

The charge controller can be used to charge the battery with solar voltage stabilization.
