24 volt vrs 12volt solar 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. You may have to buy multiple charge controllers at 12 volts or even 24 depending on the size of your solar array. Therefore it makes sense to use the voltage that already works for that system.

If your existing electrical system is 12v like in an rv which already wired and equipped with 12v appliances then you should stick with a 12v solar system. 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. 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. Rvs and motorhomes typically already have 12 volt batteries for lighting hot water heater controls ac heating controls and refrigerators.

12 volt used to be a standard for extra low voltage power systems. Today most systems are 24v or 48v and include a 230v ac inverter.
