Safe and Reliable Operation Equipped with overcharge, overdischarge, short circuit, overload, and reverse connection protection devices to ensure safe and reliable solar charger controller operation. Efficient Charging The tandem type main charging circuit greatly improves charging efficiency, enabling smoother and more efficient charging. Realtime Battery Status An LED indicator shows realtime battery status for convenient monitoring and timely charging decisions. Flexible Operating Modes Three operating modes are available: normally open mode, pure light control mode, and light control plus timing mode, providing flexibility for different application scenarios. Practical use scenarios Offgrid solar lighting: ideal for outdoor lighting such as garden, walkway, or security lights where light control and timing can optimize charging and usage. Remote monitoring and sensing: suitable for remote sensors or small solarpowered devices that require reliable charging and status monitoring. RVs, camping, and mobile setups: supports flexible operation modes to adapt to varying lighting conditions and timing needs while maintaining safe charging behavior.
