I connected this to the Nature power solar panel and 12v fully charged battery, but the green charged light never comes on. The yellow charging stays on , even when the inverter isn’t being used. Why does it always indicate it’s charging, but never fully charged? Is the controller working properly??
You can measure voltage in and out to find out if things are working, The battery voltage reads higher when battery is connected to a charger, so, 13.8 V tells me the battery is being charged at bulk stage by the controller. The CHARGED light is an indication of your battery statues. THE CHARGING light is an indication that your solar panel is working and has nothing to do with the battery statues. You can measure open voltage on the solar panel , open voltage measurement should be 18-22V in bright sun light. that is the way the panels are made. 12V panels produce 18-22V This is a 3 stage charge controller, with bulk, absorption and trickle charge, when the light is 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.. 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).
