Hi,I have the 30 amp charge controller hooked up to a 100 watt panel of yours and a costco 115 amp hour deep cycle battery with a whistler 1600 watt continuous inverter. My question is, when the solar panel is charging the battery the green light stays solid, then, its starts to flash after a while when no power is being used. Does this mean the battery is at full charge capacity and the controller has cut off the charge from the solar panel? Will it automatically make sure the battery does not over charge and over heat or explode? This is my first solar generator station I put together for charging up cordless tools and running led lights at night for work station lighting and camping. Thanks for your time. So far I love your products! They seem to be built solid.

Will it automatically make sure the battery does not over charge and over heat or explode?The flashing green battery light indicates that the battery level is full (as indicated in the manual). However, it does not mean that the controller has cut off current completely from the battery.
But not to worry: The controller's job is to charge the battery until it's full and then keep it full without over charging it (and making it go boom!). To do so, the controller applies the proper current to fill the battery and then reduces the current output from the solar panels to a trickle charge. Storage batteries self-discharge over time and require a trickle charge to remain fully charged.
In addition, if you draw power from the battery, the charge controller automatically increases the current from the solar panel to compensate AND maintain the trickle charge to the battery.
I was concerned about all this too. So, I took a few precautions that you might consider too. First, I purchased two inexpensive meters (GT Power RC LCD 130A High Precision Watt Meter and Power Analyzers) and placed them between the controller and battery/battery and inverter. That way I could see what's going in and what's going out of the battery at all times. Based on this, I could keep track of what the controller was applying to the battery and assure myself that all was working properly. The other thing I did was to watch the battery temperature with a thermometer. So far, the battery has remained at room temperature at all times.
Hope all that helps. If you have any other questions, I'd be happy to try and answer them for you.

We have lost our manual to our 30 amp PWM Charge Controller and it seems that it is having issues. I would like to know if a manual is available online with trouble shooting to see if we can fix it.Apr 4, 2016 21:50:28 GMT Darlene said:
