5.3 Battery Bank Voltage Monitoring
The heater status signal must be programmed into channels 20-26 and requires P-SCM #9135 (included
with the kit). Configure the logger channel as follows:
The battery voltage will fluctuate above 12V during the solar charging phase. When the battery dips
below 12V, the VU01 power is affected.
Note: The PS-15M charge controller comes preconfigured for the NRG supplied batteries and the low
voltage disconnect set to 11.5V. If a different battery type is used, the charging settings of the charge
controller will need to be modified to minimize the risk of damaging the system.
The SymphoniePRO data logger and iPack at the SRA station are powered independently from the VU01.
If the All-Weather PVH System loses power, it will not cause the logger and sensors to stop working.
