<p>In the process of using <a href="https://www.pvsolartech.com/solar-charge-controller-and-accesories" rel="noopener noreferrer" target="_blank"><strong><a href="https://www.pvsolartech.com/solar-charge-controller-and-accesories" target="_blank">solar controller</a>s</strong></a><strong>,</strong> we often encounter the system not working properly. The fault of the solar controller is the first component that should be checked in the whole system accessories. We can check from the following aspects.</p><p><br></p><p><br></p><p><strong>The charging indicator is abnormal.</strong></p><p>1. Check if the solar cable has fallen off.</p><p>2. The environment around the solar panel, whether there are trees covering the solar panel.</p><p>3. Whether the maximum current of the solar panel exceeds the maximum withstand current of the solar controller (some customers add solar panels later)</p><p><br></p><p><br></p><p><strong> The indicator light of the battery is abnormal.</strong></p><p>1. Remove the solar panel, check the battery voltage with a multimeter, and check whether the battery is scrapped (very low voltage)</p><p>2. If the battery voltage is too high, the load will not output and enter the high voltage protection state.</p><p>3. Check whether the battery is immersed in water or short-circuited.</p><p><br></p><p><img src="https://img80003070.weyesimg.com/uploads/q67dg84v.allweyes.com/images/15663551256304.JPG?imageView2/2/w/1000/q/100/format/webp" alt="Street light PWM solar charge controller 12V 24V Solsum 6.6F"></p><p><br></p><p><br></p><p><strong>The load indicator</strong></p><p>1.
