What is the meaning of the DC load above the solar controller?
Lamp or load class is DC DC12V / 24V / 36V / 48V, etc. If you want to AC load AC220V lamps or other, you need to add a DC-AC inverter in the middle.
Can be batteries, lights, motors and other DC equipment can be used
Because the controller output function, such as the switch, then the battery is DC energy, so if the direct output, can only take the DC load, can work properly, if you want to work on the AC load, then the need to connect the controller output DC Inverter, so that the AC load can work. My space has a lot of information about the solar system, welcome to come to view
Solar controller, there are two major functions, one is used to charge the battery, this is the solar input function. One for the battery discharge, this is the output function. Used to charge is to prevent the electric overshoot is too full, the battery charge bad. Used to discharge is to prevent the discharge too much, the battery damage. Because the battery can not overshoot, too. Discharge, it depends on what the load discharge
Solar power systems are generally DC storage, of course, there are grid-connected power generation, the output is AC, but this system is still relatively small in the country, especially for some small systems. If it is a solar street light system,
