The RENOGY 30A PWM CHARGE CONTROLLER is only a 20 amp charge controller, but it also has the smallest price tag of any of the options were looking at on this page. It’s currently available for $99.99.
Like the SolarEpic, this device also uses an advanced tracking algorithm to help the solar panels operate at the best voltage in order to produce the maximum amount of electricity.
This solar charger is also designed to help your system run as efficiently as possible because it is able to step down a higher voltage solar array to recharge a lower voltage battery bank. This makes the Tracer 2210RN a great option whether you are grid tied or off grid.
When researching this solar charger we found over 100 reviews online and the reviews are pretty strong. This device received an average customer rating of 4.2 out of 5 stars.
Many customers said that this solar charger works exactly as advertised and that they would give it their recommendation. One customer said that in his opinion it works even better than advertised. He says that he has a workshop that is completely off the grid and he gets all of his electricity from a small solar array. Because of his small solar array, he tries to make sure he gets every little bit of electricity he can out of the panels that he has and he says that the Tracer is able to charge four large 8L16 batteries that are arranged as a 12 V DC battery bank and that battery bank is used to power all of the tools, machinery, and lights in his shop.
There was also a review from a customer who says that the Tracer 2210RN Solar Charge Controller is the only one they would buy. He says that he has two 100 W solar panels mounted to the roof of his travel trailer and he did a lot of research to find the best charge controller he could for his particular situation. He said that after looking at all of the possible options he is very satisfied with his decision to purchase the Tracer 2210RN Solar Charge Controller.
