QUICK AND EASY INSTALLATION. I've connected a 150 watt solar panel mounted on my truck capper to a pair of 12 volt lithium batteries. I use this to recharge my tools using a 159 watt inverter.

This is a great enhancement to one of my portable Solar Pannels.

I am recharging an ncm lithium ion battery using this 30A charge controller, but the model I bought did not have "parameter changing". So the seller sent me the upgrade model at no charge to me and worked with me setting up the parameters for my type battery. Apparently NCM uses different charging parameters than the lifepo type batteries. I'm very much pleased with this transaction and would buy again from seller. Prime Member

I connected this no frills PWM charge controller to a small 12V 84Wh LFP battery with a 25W solar panel to power a wireless outdoor security camera. The 25W solar panel is connected to this PWM charge controller then to the 12V LFP battery. The security camera has its own internal battery that is charged off a 5V output from the 84Wh battery. I oversized the solar panel and battery so the the security camera which is normally powered by a 3W solar panel has continuous charge and the internal battery stays at 100% charge.I didn't need a higher efficiency MPPT controller which is harder on the LFP battery than a PWM charge controller. The PWM charge controller has the advantage of being able to adjust the pulse width to reduce the amount of power going to the battery versus MPPT controllers which use resistors to dump power and creates more heat in the process. An MPPT controller that is only delivering 10 percent of the power has to dump the other 90 percent of power into resistors which creates more heat. Heat equals less lifetime and other issues with the battery and controllers.The only issue I have seen with this PWM charge controller is not being able to auto recover from an error condition. I had a problem with a wire going to the battery from the PWM charge controller that was not solidly connected and with the wind blowing on the wires going into my utility box it would cause an error if the PWM charge controller got momentarily disconnected from the battery. The PWM controller would register an error and stop charging the battery even if the connection was restored. The only way to get the PWM charge controller to begin charging again was to disconnect both the battery connection and the solar panel connection so the unit would power off. I have two other MPPT charge controller connected to multiple arrays of solar panels and if a battery disconnects temporarily the MPPT controllers stops charging but starts again if the battery connection is restored.I like the ruggedized design of the PWM charge controller and the price is inline with other 30A charge controllers and this one has MC4 panel connectors and Anderson ports which is a nice plus.

I purchased this charge controller in September and it completely stopped working within 4 months. I emailed the seller seeking help but did not get a response.

Works great for maintaining my lead acid battery. It was able to fully charge my battery from a 200w solar panel even when the battery was well below proper the proper voltage.

Even brought one back from a no charge state with a cheaper controller. Highly recommend

Love the Bluetooth feature!
