Solar power is massively accessible to us and is free of charge to utilize, furthermore it’s a limitless, endless natural source of energy, simply reachable to everyone. We certainly have talked about easy methods to use solar panels for producing electricity from solar or sun power, in this post we intend to talk about a basic arrangement which is able to allow us to utilize solar energy for working our household appliances.
A solar panel has the capacity to change sun rays into direct current at lower possible levels. For instance a solar panel might be specific for providing 36 volts at 8 amps under optimal circumstances, but we are not able to utilize this magnitude of power for working our domestic appliances, since these home equipment can work only at mains potentials or at voltages in the ranges of 120 to 230 V. More completely the current ought to be an AC and not DC as generally get from a solar panel.
We now have discover several inverter circuits submitted within this blog and we certainly have analyzed how they function.
Inverters can be used for transforming and upgrading low voltage battery power to high voltage AC mains levels.
Consequently inverters may be efficiently useful for changing the DC from a solar panel into mains outputs that will surely power our domestic equipment.
Fundamentally in inverters, the change from a low potential to a moved up high mains level turns into possible due to the high current that’s usually offered by the DC inputs such as a battery or a solar panel. The overall wattage continues to be the same.
For instance if we supply an input of 36 volts @ 8 amps to an inverter and get an output of 220 V @ 1.2 Amps usually means we simply altered an input power of 36 × 8 = 288 watts into 220 × 1.2 = 264 watts. For that reason we are able to observe that it’s absolutely no magic, just changes of the specific guidelines.
If the solar panel has the capacity to produce sufficient current and voltage, its output can be utilized for directly functioning an inverter and the linked household devices and also at the same time for charging a battery. The charged battery can be used for running the loads via the inverter, during night times when solar energy is not found.
In spite of this if the solar panel is smaller in size and not able to produce adequate power, it might be utilized simply for charging the battery, and evolves into effective for operating the inverter only after sunset.
Making reference to the circuit diagram, you can easily experience an easy set up utilizing a solar panel, an inverter and a battery. The three units are attached by means of a solar regulator circuit that directs the power to the particular units after suitable stipulations of the obtained power from the solar panel.
Presuming the voltage to be 36 and the current to be 10 amps from the solar panel, the inverter is chosen with an input operating voltage of 24 volts @ 6 amps, offering a total power of about 120 watts.
A fraction of the solar panels amp which amounts to about 3 amps is spared for charging a battery, meant to serve after sunset.
We also believe that the solar panel is installed over a solar tracker so that with the ability to provide the stipulated needs provided that the sun is noticeable over the skies.
The input power of 36 volts is placed on the input of a regulator which trims it down to 24 volts.
The load hooked up to the output of the inverter is picked such that it does not force the inverter more than 6 amps from the solar panel. From the remaining 4 amps, 2 amps is supplied to the battery for charging it.
The remaining 2 amps are not employed for the sake of sustaining better effectiveness of the whole system.
The circuits are all those which has been previously mentioned in my blogs, you can easliy notice how these are generally smartly set up to each other for applying the needed procedures.

For Charging Batteries up to 250 AH
The charger section in the above circuit could be accordingly improved for allowing the charging of high current batteries in the order of 100 AH to 250 AH.
An outboard transistor TIP36 is properly built-in across the IC 338 for helping the essential high current charging.
The emitter resistor of TIP36 needs to be determined correctly usually the transistor may indeed blow off, do it by trial and error technique, begin with 1 ohm at first, then slowly go on lowering it until the needed quantity of current turns into attainable at the output.
