[. . . ] POWER MASTER **Premium MPPT Series** SOLAR CHARGE CONTROLLER PM-SCC-50AM / PM-SCC-80AM PM-SCC-40AMW / PM-SCC-80AMW Installation and Operation Manual Chapter 1 Installation 1. 1 Loads Requirement The Premium MPPT Series plays a major role in planning your PV system. The first step in planning an efficient PV system is to calculate the load requirement. In order to calculate the anticipated load requirement, it is important to determine average and peak load consumption. The possible load growth should also be taken into consideration when planning the load requirement because loads hardly remain static and they grow more frequently than they reduce. 1. 2 Battery Voltage System After the estimate of the power requirement, the required power from the battery will be the next consideration in planning the system. [. . . ] A-01=Operation Only This setting allows the “Operation” and “Initialize” to be changed or displayed. A-02: Init Parameters Use Constant A-02 to initialize the user constants. When initialized, the user constants will return to their factory preset values. You should normally record the setting of any constants that are changed from factory presets. Settings: A-02=Preset Setting This setting allows to initialize the user constants to factory settings. A-02=No Initialize (Factory Setting) This setting does not initialize any user constants. A-03: Password 1 A-04: Password 2 These two constants are reserved for the factory to test and set the functions. Go to any display of A-xx and press DOWN key and hold it, then press ESC key at the same time till A-04 constant occurs. Make sure the password 1 in A-03 must be different from the password 2 in A-04. Above procedure completes locking the constants setting and no more programming selection would appear. A-01 would only display Operation only and would not display Constants Set. Enter the password in A-03 to be exactly the same as the one earlier set in A-04 2. When the password in A-03 matches the one earlier set in A-04, the unlocking is completed. *** Main Menu*** Programming Group B Battery Setup B-01: Set Battery Voltage During initialization of Premium MPPT Series, it will detect and ask the installer to confirm the battery voltage found is correct. In almost all circumstance the Premium MPPT Series will correctly detect battery voltage. Use Constant B-01 to change the battery voltage if the battery voltage displayed by the Premium MPPT Series is different from the installed batteries. The selection range of the battery voltage is 12V (Factory Setting), 24V, 36V and 48V. B-02: Set Battery Type Use UP or DOWN keys to allow the installer to change what type of batteries it is connected to (Flooded, Gel, AGM) Premium MPPT Series. The default “BATTERY TYPE” is GEL Please be sure to select the type which matches the system’s batteries. This setting controls battery charging voltages in B-06 and B-08. 5-5 B-04: Set Battery Capacity This setting controls battery charging amperages and other settings. The factory setting for CAPACITY is 1000 amp hours for PM-SCC-50AM, 1600 amp hours for PM-SCC-80AM, 800 amp hours for PM-SCC-40AMW and 1600 amp hours for PM-SCC-80AMW. At full output capacity a PM-SCC-80AM can deliver 80 amps to a battery, this amount of amperage (current) is equal to the C/10 (capacity divided by ten) rate of a 1600 amp hour battery and, as such meets most manufacturers recommendations for minimum PV charging capacity. [. . . ] When FAN ON is selected, the fan test is conducted as the O-06 screen remains. O-07: Software Version The software version displayed is important and useful when contacting Power Master Technical Support. *** Main Menu*** Data Log G-01: EnergyHarvest Today 1 This screen displays how much the solar energy was harvested “Today” in kWHr and AHr unit. G-02: EnergyHarvest Today 2 This screen displays how much time the charger was in Float mode “Today”. [. . . ]
