If it is off for 24 hours, the load will automatically turn back on when the charging current stops. The load feature is a handy feature for controlling lighting. This is a feature specifically designed for lighting applications. If you have a ZHCSolar solar charge controller, it may have a load feature. When the battery voltage decreased to the over discharge level, the LED Light turns red, at this time the controller will automatically shut down the output to remind the user to recharge the battery in time Load Light Blinking When the battery voltage decreases to under voltage level, the LED Light on Solar Charge Controller turns orange/yellow. when it is full, the status indicator is green and flashing slowly. In LED Mode, when the battery is Charging, the led light indicator is green and always on. After the battery is full, the power bar will be full.īattery icon Fast Flashing Means the Battery has been fully Charged, the battery is running well.īattery icon Slow Flashing Means the battery is losing power and needs to be charged in time. In LCD, Battery icon Blinking has a very straightforward meaning, with a power bar inside, and the battery charging process will dynamically show how much power has been charged into the battery. Usually the problem is the solar panel junction box solder joints bad solder or not solder caused a broken circuit, or positive and negative terminals connected to the reverse. This situation is normal at night, you should check whether the solar panel is damaged. if there is no light, It means that the solar panel is not generating electricity. PV Light Flashing in LED means the same, if there is any power input, it will in Green always. The panel icon starts flashing to indicate that the solar controller has detected solar input, and then it will always light up to indicate continuous and stable solar input. This is the time to check if the solar panel has enough voltage or if there is a wiring error. The panel icon will not light up when the controller does not detect any power input from the solar panel. Typically, there are 3 main icons/symbols that will show up: solar panel, solar Battery and load. When some controllers do not have a display, they use led lights flashing to convey information, which we will also cover in the article.
Many users may notice that the icons on the controller display will flash, today we will reveal the secret of the flashing icons.
These carry different meanings and purposes, and learning to read the solar controller is one of the necessary steps to properly use the solar controller. You will notice that almost all solar controllers come with a display when you purchase, whether it is an mppt controller or an economic pwm controller, this display comes with a lot of information containing icons, symbols, text and numbers.
