20A PWM Solar Charge Controller 12V 24V Lithium Battery Regulator sunyee

If you are looking for a solar controller to charge your battery and keep unnecessary damages at bay, please look no further, this PWM solar controller must be the one you are looking for. This solar controller is ideal for off-grid applications on 12V-24V systems and it uses a 3-stage algorithm—bulk, absorption and float—to increase the lifespan and performance of batteries accordingly to battery type lead acid battery (flooded, GEL and AGM) and lithium battery ( Li(LiCoMn)O2 and LiFePO4). And this is further enhanced by the programmable voltage it integrates. In addition, this solar controller can be connected to 2 solar panels, which can increase charging efficiency. It also offers a built-in LCD display, through which you can have a real-time view of the system status. And an array of built-in protections-low/over voltage, short circuit, overcharge/ over discharge, overcurrent, overload and reverse polarity protection-offer an extra layer of protection.
