1. The array Mp is the voltage where the product of output current and voltage Amps x Volts is greatest which falls on the knee of the solar module l V curve as shown on the left in Figure 4 1 Because traditional controllers do not always operate at the Miss of the solar array energy is wasted that could otherwise be used to charge the battery and power system loads The greater the difference between battery voltage and the va of the module the more energy is wasted MPPT technology will always operate at the maximum power point resulting in less wasted energy compared to traditional controllers Conditions That Limit the Effectiveness of MPPT The V_ of a solar module decreases as the temperature of the module increases In very hot weather the V may be close or even less than battery voltage In this situation there will be very little or no MPPT gain compared to traditional controllers However systems with modules of higher nominal voltage than the battery bank will always have an array an greater than battery voltage Additionally the savings in wiring due to reduced solar current make MPPT worthwhile even in hot climates 14 WARNING Risk of Explosion Equalizing vented batteries produces explosive gases The battery bank must be properly ventilated CAUTION Equipment Damage Equalization increases the battery voltage to levels that may damage sensitive DC loads Verify all system loads are rated for the temperatu2.
