Best Solar Charge Controllers: 10 Top Selling Solar Charge Regulators for Off-grid Systems
Solar charge controller is an essential part of an off-grid solar or wind power system. As you know, it regulates flow of power from PV panels to battery. It is the way solar power solutions manage to prevent overcharging of the connected batteries. Likewise, solar charge controller blocks reverse current flow from battery to panel. Here we have a list of 10 best solar charge controllers to let you find the best one for your DIY off-grid solar kit.
10 Best Solar Charge Controllers
Roughly speaking, all solar panels over 5-watt capacity require solar charge controllers. In fact, all all-in-one solar generators tout built-in charge controllers. If you put together your own DIY solar generator for camping or home, you must include a solar charge controller. We mainly have two varieties of charge controllers on market, PWM and MPPT. The second one, as you know, is rather advanced with more efficiency and capacity over 60 amps. Meanwhile, small solar power solutions require only the less-expensive PWM controllers.
Below we have a list of 10 best solar charge controllers. We have compiled the listicle after a detailed research. There is a huge number of solar charge controllers on market in different capacities and style. Our list indeed covers all popular variants, containing both PWM and MPPT controllers. Moreover, we have included charge controllers friendly for both camping solar kits and big home-based solar systems. Stay tuned with us.
As the above diagram shows, a charge controller acts like an intermediary between panels and battery. Well, it monitors high voltage from the panels and stabilizes it before letting go to the battery. Of course, it increases life of battery and helps charge it fully with no overcharge or discharge. Meanwhile, it also directly discharges energy to power your DC load if you have any. Anyway, below is our list of the best solar charge controllers.
