SOLAR CONTROLLERS, SOLAR REGULATORS, SOLAR CHARGERS
These are the various names by which solar controllers are known.
Although some controllers are more technologically advanced than others -They all generally perform the same function – which is to control the charge into the battery and manage the batteries health. As you would expect, some controllers do this job better than others.
There are two types of controllers:
PWM or Pulse width Modulated
The PWM controller is in essence a switch that connects a solar array to the battery. The result is that the voltage of the array will be pulled down to near that of the battery.
MPPT or Maximum Powerpoint Tracker
The MPPT controller is more sophisticated (and more expensive): it will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement of the battery plus load. Thus, it essentially decouples the array and battery voltages so that there can be, for example, a 12 volt battery on one side of the MPPT charge controller and panels wired in series to produce 36 volts on the other.
OUR PRODUCT RANGE CONSISTS OF HIGH QUALITY PWM CONTROLLERS FROM EP SOLAR ranging from 10A to 45A.
These include day night switching capability as well as timer functionality.
WE CARRY TOP OF THE RANGE VICTRON MPPT CONTROLLERS
ranging from 15a with 100V input and 12 or 24V output to 250V input with 12 to 48V output.
