How to choose a suitable solar controller?

Today, solar controller has become a word that is no longer unfamiliar. Its common use is to provide load power for inverters and to charge accumulators in solar power generation systems. So what should we choose when we use it.

First of all, we need to choose a battery panel with a higher configuration, so that the voltage when exiting the protection can be set lower according to our own needs, the voltage of the battery will be normal, and the solar controller can also be used normally. The second is the problem of heat dissipation. The controller can be well dissipated during use to prolong its service life. Then there is its output period. Now more and more consumers are not satisfied with the output period efficiency of the existing products, so we can choose the appropriate controller according to our needs, change its output period according to the needs, and set it The closing time can be greatly reduced.

The latter is line loss compensation, which is a difficult function to control at this stage, because it requires the control of software equipment, and then compensates according to the length and diameter of different lines. Under low voltage conditions, the line loss function is very important, because when the voltage is low, the line loss will increase, and then the output voltage will be lower than the input voltage, resulting in a smaller capacity of the accumulator. Therefore, in our actual selection, we should choose a cable that is not particularly thin, and the length of the cable should also be moderate.

So when we choose a solar controller, we should choose the controller that suits us according to the performance it needs.
