Another limitation is that the Voyager only works with 12V batteries. The best solar charge controller will provide many benefits. When it comes to MPPT controllers, they reign king in terms of battery regulation. They do a great job protecting the battery but they ‘waste’ some power. It doesn’t make sense to use MPPT technology for small solar systems. You can easily check the status of your battery, how much power the solar panel is producing, and other performance data. The EPEVER dual solar charge controller is not compatible with lithium-ion batteries. Most solar charge controllers come equipped with a variety of extra features. The meter displays much more data and gives you more control than the basic LCD display on the charge controller. Prevents reverse charging: At night, your battery can discharge because of the voltage difference between the solar panel and the battery. Some complain that it’s not very efficient. Wiki researchers have been writing reviews of the latest solar charge controllers since 2019. This site participates in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. By quickly tracking the maximum power from the solar panels, it can change the voltage to deliver maximum energy to the batteries. The controller will reduce the voltage if it detects the battery temperature is rising. You generally don’t need a charge controller if the solar array puts out less than five watts of powerfor every 100 amp hours of battery capacity. This ensures your system is at peak performance all the time. You can also see performance data from the last 128 days and configure various settings.
