SunReadFarm EV solar charger


Uninterrupted solar voltage stabilization direct charging,

Controller synchronization battery instant voltage
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 automatic buck-boost and MPPT  regulated charging. A new-architecture solar controller is very suitable for outdoor use of Electric Vehicles .

1. Simple solar BMS controller.
2.The battery can be charged up to a single solar voltage regulator. Multiple battery voltage points can be set to control the voltage.The maximum current power supply when charging.
3.Solar voltage stabilized direct charging without interruption, battery synchronous pressure measurement.
4.Normal battery voltage, full battery voltage. When the battery reaches the specified voltage value, the charging will stop.
5.The battery is charged only when it is drained, which makes charging safer.
6.The controller charging method is fast charging mode.
7. Suitable for lithium batteries, lead-acid batteries, etc. Can be used for outdoor power generation, car charging       
    generator backup, and EV charging.
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 charging controller can be applied to electric vehicles, locomotives, golf carts, and industrial equipment requiring constant voltage input. The products are exported to the United States, Canada, Europe and major global markets.
