in overcharging if charger voltage is not compensated. Battery manufacturers, therefore, specify
battery charging / discharging voltages and capacities of Lead Acid Batteries at Standard Room
Temperature of 25º C.
3.4.4.2 When the battery electrolyte temperature varies from the Standard Room Temperature
of 25º C, the values of charging / discharging voltages will be compensated based on the actual
battery electrolyte temperature using parameter called “Battery Temperature Compensation
Coefficient”. In this controller, this parameter is set at -3mV/ºC/Cell i.e. (i) -18mV/ºC for 6-cell,
12V battery or (ii) -36mV/ºC for 12-cell, 24V battery.
3.4.4.3 The controller has built-in Temperature Sensor for indirect and approximate sensing of
battery temperature. For this, the controller has to be placed very close to the battery . This built-
in sensor is the default sensor if the optional Remote Battery Sensor Model MSK-TS is NOT being
used.
3.4.4.4 For accurate sensing of the temperature of battery electrolyte, it is recommended that
the
optional Remote Battery Temperature Sensor Model No. MSK-TS is used. This Temperature
Sensor comes with 3M/10ft cable with a cylindrical Temperature Sensor Head for battery end and
2-pole Female Connector for the controller end. Install this sensor as follows:
• Attach the Cylindrical Sensor Head half way down the vertical side of the warmest part of
the battery in the battery bank so that the sensor picks up the temperature of the electrolyte.
Use 1 mil “PVC Pipe Wrap Tape” to tape the sensor to the battery (
pre-clean the battery
surface with Rubbing Alcohol prior to placing the tape )
• Insert the 2-pole Female Connector into the Jack marked “Temp Sensor” ( 8 in Fig 2.1 )
3.4.4.5 When the optional Remote Battery Temperature Sensor Model MSK-TS is plugged into
the controller, the internal Temperature Sensor ( Section 3.4.4.3 above ) will automatically be
disabled.
3.4.5 Step 5: Install Fuse
Install 30A fuse "F1" in the battery circuit, (not included) as shown in Fig 3.2.
3.4.6 Step 6: Confirm Power ON
When battery power is applied, the controller will start operating. Refer to Table 4.1 under
Section 4.7 for operational information through the Solar Panel / Battery / Status LEDs (
1, 2 & 3
in Fig 2.1 ).
