Power 60a solar charge controller

  Smaller charge controllers will often only have preset charge settings. 

If the battery charging requirements are not sufficiently met with these presets, a controller with more settings options can be selected. Custom settings can be simple adjustments to voltage set points, particular applications or environments. For example, a system which does not cycle much can be set up with reduced daily absorption time, which is the amount of time before it puts the battery into float. What is Maximum Power Point Tracking?

    Panel tracking - this is where the panels are on a mount that follows the sun. 

These optimize output by following the sun across the sky for maximum sunlight. 

These typically give you about a 15% increase in winter and up to a 35% increase in summer.

This is just the opposite of the seasonal variation for MPPT controllers. Since panel temperatures are much lower in winter, they put out more power. And winter is usually when you need the most power from your solar panels due to shorter days.

   Most MPPT algorithms only collect the voltage and current of photovoltaic cells and track them based on the idea of disturbance observation, but there is no way to know whether the change in the output power of photovoltaic cells is caused by disturbance or changes in the external environment, so when the environment changes more When it is fast, mistracking is easy to occur. The solutions mainly fall into the following categories:

Open loop control according to the environment;

Make the power change caused by the algorithm disturbance greater than the power change caused by the environmental change;

Identify and compensate for power changes due to environmental changes.
