Product Description:

Sizing a stand-alone PV system requires a different approach than a grid-connected array. The load, or demand, on the grid-connected system was able to be quantified in Watts due to its simplicity. For stand-alone sizing, appropriate voltages and currents must be used in order to increase transmission efficiency and reduce the risk of overloading the system. Because the product of voltage (V) and current (I) equals the power (P) of the system in Watts, these values can be altered inversely of each other while keeping the same system Wattage. (P = I x V)
