That is normal operation. This is a PWM charge controller, It should assume 3 stage PWM charging when you connect to battery. The CHARGED light is an indication of your battery statues, it detects batteries differently, normally a strobing green light means you battery is depleted, a flashing light is 80% full. The CHARGING light is an indication that your solar panel is working and has nothing to do with the battery statues green light. the yellow light will turn on in during the day when panel is producing voltage and disappear at night. You can measure open voltage on the solar panel, open voltage measurement should be 18-22V in bright sun light. This is a 3-stage charge controller, bulk, absorption and trickle charge, with different voltages introduced to battery for each stage. When you connect charger to battery your voltage reading on battery terminal should be between 12.9V and 14.2V, indicating that the battery is receiving charge. Please keep in mind that a solar panel connected through a controller will NOT charge a dead battery. When the light is solid green, you are in the last stage and the battery is trickle charged, when full the light will blink. At this stage the charge will be cut off to the battery, the light should go off, indicating that the charge has been cut to the battery, or it could stay in permanent trickle mode charge with light blinking or solid. There are several factors that could affect the charge to your battery. If the battery is receiving charge, it should read higher than or around 13V while connected. Please test your battery at rest w/o being connected to the charge controller, to see what the voltage reading is. If your battery is in good condition, then you would need to make sure there is no lose wire. Both lights can be on at the same time, Charged LED light is “green” when battery reaches 14.2V. at this point the controller will cut off the charge to the battery to prevent overcharge. The Charging light is “yellow” when the panel is producing power to the battery. If both lights are on, that is an indication that the battery is full, the charge to the battery has been cut off and the panel is still producing power. when charge is cut off from panel, you will read actual voltage at rest( full (12.6-12.7V). A solar panel will not charge a dead battery, when connected through a controller. At 10.7V, the battery is fully discharged, the 10.7V shutoff, means that the controller will not recognize the battery at this point, and therefore, the controller will not even turn on. if the battery ever gets discharged that low, then you have to charge it, using other means, other than the solar panel, to bring the battery up to desired voltage level. Your battery has to have readable voltage, so that the controller can recognize it, no set up is needed, it automatically detects voltage and kind of battery, it will charge any 12V battery, lead acid type, whether it’s a mower battery or a deep cycle battery. The battery voltage reads higher when battery is connected to a charger. Thank you. Please call Nature Power tech support at 1800-588-0590 for any more questions.
