PV*SOL Expert 6.0 - Manual Stand-Alone System Inverter Voltage Check For the AC appliances, the battery voltage is compared with the inverter voltage. Both components are loaded from the database and have to be checked against the system voltage. Battery Voltage Check If your system has direct battery connection, the battery voltage sets the modules’ working point. The battery voltage is dependent on the charge condition. PV*SOL ® works with a characteristic curve for the (averaged) voltage. These benchmark figures are compared with two working points for the modules’ MPP voltage, ie the MPP voltage at 500 W/m² and 25°C, and at 1000 W/m² and 25 C (STC) A message appears if the minimum battery voltage is less than 60% and the maximum battery voltage is larger than the corresponding MPP voltage. Simulation is blocked if the minimum battery voltage is less than 40% and the maximum greater than 110% of the corresponding MPP voltage. MPP Tracker Output Check If an MPP tracker is used, a check is required to see if the MPP tracker’s output corresponds to the PV output. If the figure is exceeded the PV energy produced will be reduced, if the figure is not reached the MPP tracker works at a poor efficiency rate. A message appears if the MPP tracker’s output is less than 90% and more than 120% of the PV output. MPP tracker outputs less than 33% and more than 500% of the PV output are not accepted. MPP Voltage Check The MPP tracker’s MPP tracking range is compared with the module array’s MPP voltages. The voltage decreases with increasing temperature and decreasing radiation. The definition of the working points is as described in the grid connected system check. For both of these working points the module array’s MPP voltage is calculated and compared with the MPP tracker’s MPP tracking range. A message warning of discrepancies appears if the MPP tracker’s threshold values vary by more or less than 10% from the modules. Not reaching the lower MPP threshold of around 50% or exceeding the upper MPP threshold of around 25% is not permitted. Cabling checks are made on both types of systems, and on each PV array. DC Cabling Check The flow of current through the cabling under standard test conditions (STC) is defined by the module current flow under STC and the number of parallel-connected modules in an array. This should not be more than the permitted electrical capacity of the cabling. 108
System Check In the programme, the maximum capacity for group 3 insulated copper wiring is based on the Federation of German Electricians’ regulations. Relative cabling losses are calculated from the cabling resistance, electricity and voltage under standard test conditions. Cabling losses of above 20% are not accepted and PV*SOL ® produces a message when these are above 5%. 109
