12 Volt Vs 24 Volt Solar Panel Wiring
1 000 watts 83 amps 12 volts.
12 volt vs 24 volt solar panel wiring. You need 4 six volt batteries or two 12 volt batteries. The higher the current measured in ampere or amps the larger the wiring and circuit protection components need to be. The 150 watts solar panel is a 24 volt. You could have between 8 and 12 panels in a series.
4 000 watts 83 amps 48 volts. 2 000 watts 83 amps 24 volts. This is so because increasing the voltage of a system causes a reduction in the current through it and in turn reduces the size of the wires you need. This means the wiring of the house does not have to be different from any other grid connected household and cabling cost is greatly reduced.
12 volt used to be a standard for extra low voltage power systems. You must be careful not to exceed the maximum battery system voltage. So if you wired the same panels from before in parallel the voltage of the system would remain at 40 volts but the amperage would increase to 10 amps. Wiring solar panels in a series when connecting two or more solar panels in a series your amp charge is stable while your voltage multiplies.
The solar panel puts out 6 25 amps at peak. Wiring solar panels in parallel causes the amperage to increase but the voltage remains the same. The reduction in wire size cuts down the costs as the thicker the wire the more costly it is. You may have to buy multiple charge controllers at 12 volts or even 24 depending on the size of your solar array.
At 12 volts the flexmax 60 fm60 400 600 can only handle up to 750 watts 24 volts 1500 watts and at 48 volts 3000 watts of solar modules. If you have two 12v solar panels each rated at 5 amps you will retain the 5 amps but would get a 24 volt charge. Most residential solar systems operate at 24 or 48 volts and supply power to the house with a 230 volt a c inverter. 20 000 watts 83 amps 230 volts.
High currents require larger diameter cables and fuses breakers both of which are expensive. I believe almost all rv systems are based on 12 volt panels. We advise that you get an electrician to wire your house for 230v ac. Using a 24 volt supply instead of a 12 volt supply greatly reduces the wiring cost to almost half the original cost.
The converter will use up from 5 to 10 of the 150 watts.
