Connecting a solar panel directly to a battery.

Best 12v battery solar charger. A complete note on solar panel installation with calculation examples the dc load light fan etc is directly connected to the charge controller and can be fed up by two power sources.

The thickness of the wire will depend on the type of charge controller you get. This is why you can t connect your solar panel directly to your battery. Using converter you can charge mobile also. We therefore aim to have alternating current ac as this is more powerful and is what most appliances run on.

But solar panels are rated in watts so some simple conversion math is needed. I ve been told that you can connect solar panels directly to the battery if they do not exceed 2 of the batteries capacity. This means the solar panel each day will have to supply 1 percent of the battery s total amperage to maintain full charge. Exceeded for minutes to hours i used to connect a 60w solar panel to my car battery every few months and let it charge to equalize it i don t recall the peak voltage but it went over 15 5 for hours.

If the house panel is connected to the power grid the inverter can be programmed to sell excess power back to the power company. Once the battery terminal voltage. The charge controller also senses if the battery is full. The direct load can be directly powered up through solar power and a charge controller during the sunshine day time and during the shading night the dc load can be powered up using the battery.
