basic information
【Features】 ● Long Battery Life: Adopts a PWM charging circuit with three-stage charging: bulk, absorption, and float. The SunKeeper can use a temperature sensor (optional) for temperature compensation. It can start charging even with a 0V battery. ● High Reliability: Operates normally even at high temperatures of 70°C for solar cells. It can be connected to a junction box and used outdoors as is. Additionally, it uses a power MOSFET with low on-resistance, eliminating the need for backflow prevention. ● Easy Connection: Fits the knockout hole M20 of standard junction boxes for solar modules. The ends of the SunKeeper wires are Y terminals, allowing for easy connection to the terminal block of the solar module. *For more details, please refer to the catalog download.
