12 Safety Protections
| 1.Automatical Voltage Switch | 2.Over charging and over discharging protection | 3.Overload protection | 4.Short Circuit Protection |
|
Ldsolar controller can switch the system voltage according to the battery voltage automatically
|
Ldsolar controller can prevent the battery from over charging and over discharging and increasing the battery life. | Ldsolar controller will cut off output ,if the curent of output is more than 1.1 times rated current | When the solar panel or the Load is short circuit,Ldsolar controller can stop charging or turn off the output immediately.It can prevent battery from damaging |
| 5.Reverse Connected Protection | 6.Battery Over Voltage Protection | 7.Auto Temperature Compensation | 8.Over Temperature Protection |
| If the polarity of battery or solar panel is reversely connected ,Ldsolar controller will not be destroyed.After correcting the connection,Ldsolar controller will work normally. | When the voltage of battery was more than 16.5V(12V system),Ldsolar controller will turn off charging and output. | The in-built sensor in Ldsolar controller can sense the outside temperature and regulate the battery charging and over discharging.It can increase battery life upto 30% | When the temperature of inside controller is uptp 85℃，the controller will stop charging and discharging. |
| 9.Lighting Protection | 10.Multiple load work modes | 11.Prevent Reverse Flow of Current | 12.Battery Type Selection |
| Ldsolar controller could protect small induction thunder | Ldsolar controller can automtically detect when the day sets and night begins and set a working time.It can switch on /off the output automtically | During nighttime when voltage of battery is more than that of solar panel,current could start flowing from battery to panels,This could be very harmful for solar panel.Ldsolar controller ensures that the current always flow from panels to batteries,and never in the reverse direction. | Ldsolar controller is deigned for multiple battery type-Sealed,Gel,Flooded,LiFePO4 and LiO2 to ensure efficient charging. |

Customized large-diameter red and black terminals (Patented)
*Customized large-diameter port is more suitable for solar systems that require large-diameter wires to reduce the voltage drop and losses in wires
*The red and black design allows customers to distinguish positive and negative more intuitively, and good customer experience
*The shrapnel is designed in the crimping frame to avoid breaking the wire and causing poor contact
