To do this with a converter, it´s necessary to put batteries to guarantee the necessary energy when the photovoltaic panels don't receive enough solar radiation to produce the intensity that is needed If you want to control the current to your load, then the simplest method is to use avariable resistanceas proposed by some colleagues before me.
I suggest to use the solar regulators, or charge controllers as they are also called, the aim is to regulate the current from the solar panelsto prevent the batteries from overcharging. Overcharging causes gassing and loss of electrolyte resulting in damage to the batteries.
The photovoltaic generator (GPV) is connected to a DC/DC converter in order to track the maximal power produced by the GPV whilst adapting its voltage to that of the network (or the load). In general, the types of used controllers are PI controllers, sliding mode controllers, heuristic-type controller, etc. .
At the heart of this process is the solar charge controller’s ability to discern the battery’s current state of charge. It does this by measuring the voltage, which gives an indication of the battery’s overall charge level. Based on this information, the controller adjusts the power output from the solar panels.
