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.
1.5 Shunt (BCS) The Shunt is an optional component and it is required for the Premium MPPT Series to achieve to the optimal operation levels and it functions as a hub for connecting measurement sensors. The main purpose of the shunt is to allow the Premium MPPT Series to measure current drawing into and out of the battery. DC load centers is where the Premium MPPT Series Shunt is recommend to be placed at. Or installing it in an electrical enclosure is also acceptable.

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.
B-04: Set Battery Capacity z z z 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.
B-07: Set Absorption Time z Use Constant B-07 to adjust the length of Absorption time. The factory setting is 2 hours (displayed as 02:00). B-08: Set Float Voltage z Use Constant B-08 to adjust the Float voltages. The default set values are based on the battery type and capacity selected. It is not advisable to change default settings unless advised by the battery manufacturer or supplier. Battery Type Float Volts Range Factory Setting FLOODED 12.9V~14.2V 13.8V AGM 12.8V~14.2V 13.2V GEL 12.
B-11: Set Days Between EQU z This constant is only displayed if Flooded is selected as battery type (B-02). Use Constant B-11 to select the number of days between equalization charges. The factory setting is OFF. B-12: Manual Equalize z This constant is only displayed if Flooded is selected as battery type (B-02). Use Constant B-12 to choose between manual and automatic equalization settings.
z z z Type (C-01). The scan frequency is settable from 1 minute to 4 hours and the factory setting is 1 hour. Press the UP and DOWN key to increase or decrease the length of time. P and O (Perturb and Observe) will run a full scan at the set time interval (frequency) and then do P and O scans at shorter intervals in between. Scan and Hold will run a full scan at the set time interval (frequency) and then hold the resultant MP until the next interval.
z z z functions will be added in the future. Use Constant D-01 to select the Auxiliary Relay 1 mode and what it is based on.

F-02: Premium MPPT Series Parallel Addr z z A Premium MPPT Series assigned as Master or Standalone is always addressed 01 automatically so the address assignment in F-02 is only available for the slave units. The maximum slave address number is 16 and the factory setting is 2. Group O Operator O-01: Set CLOCK Mode z z z This is the same display as in the initialization setup of battery. Use Constant O-01 to change and select the hour format displayed between 12 Hour and 24 Hour.
z consumes a fair amount of quiescent current, it is recommended that the on time be as short as possible. Press ENTER key to enter the setting and press UP and DOWN key to turn off from NEVER (always on) or 1 to 10 minutes in 1 minute increments. Note: When the backlight turns off, pressing any key will turn it back to U-00 display screen. O-06: Fan Test z z Use Constant O-06 to test if the fan can be forced to be ON or OFF. When FAN ON is selected, the fan test is conducted as the O-06 screen remains.
charging, reduce loads, or expand the PV array to ensure that batteries are fully recharged. For maximum service life batteries should be fully recharged at least once every five to ten days. G-03: Set Day LOG# (1-90) z Use G-03 to set the Day Log number to display the energy harvested from PV array (shown in G-04 and G-05) by Premium MPPT Series over a period of time.
z Press ENTER key and use UP and DOWN keys to select between Today’s Data and Logged Data and then press ENTER key again to clear the selected data.
Chapter 6 Trouble Shooting z z Proceed as follows for a quick detection of common faults. Consult your Power Master dealer if the fault cannot be resolved. Problem or Error message Cause Solution When the PV array voltage is higher than 140VDC for PM-SCC-80AM or higher than 240VDC for PM-SCC-80AMW, the battery charging stops. Make sure the PV array voltage is within the rated voltage range. The ambient temperature is too high and it causes the over temperature of heatsink.
