Actually the losses in wiring and conversion exist If the solar module s Vmp is greater than the battery voltage it follows that the battery current must be proportionally greater than the solar input current so that input and output power are balanced The greater the difference between the maximum power voltage and battery voltage the greater the current boost Current boost can be substantial in systems where the solar array is of a higher nominal voltage than the battery e An Advantage Over Traditional Controllers Traditional controllers connect the solar module directly to the battery when recharging This requires that the solar module operate in a voltage range that is below Page 15 the module s Vmp In a 12V system for example the battery voltage may range from 11 15Vdc but the module s Vmp is typically around 16 or 17V Figure 4 1 shows a typical current VS voltage output curve for a nominal 12V off grid module Current VS Voltage in 12V system Output power in 12V system eTracer Maximum Maximum Power Power Point Traditional lt Point te Controller Operating Range a Xx Typical Battery Voltage Range CURRENT 10 1517 VOLTAGE 10 1517 VOLTAGE Figure 4 1 Nominal 12V Solar Module I V curve and output power graph The array Vmp is the voltage where the product of current and voltage AmpsxVolts is greatest which falls on the knee of the solar module I V curve as shown in Figure4 1 B
