[. . . ] 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. [. . . ] 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. Users are not allowed to set these two constants. Finish setting all the programmable constants to the desired values. Change A-01=Operation Only, factory setting is A-01=Constants Set. Use UP key to go to A-03 to enter the password 1 (max. 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. Finally, press ENTER key to finish “lock” setting. 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. A-01=Constants Set would appear again for programming. *** 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. [. . . ] O-08: ***Bootloader*** This is the Bootloader initiation display. *** 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”. It is valuable to know that the charger enters Float mode because this is a clear indication that the batteries have been fully recharged. [. . . ]
