2. Quick Start Guide
2.1. System Concept
The following diagram shows a simple connection drawing of a Solar Power System:
The System shown has 1 x Array Input, 1 x Battery, and 1 x Load Output but the principle is the same if
the system has more than one Array Input and more than one Load Output.
The MSRx Charge Controller provides connections for the Array Input, Battery and Load Output.
It controls the Array & Load Relays to control the Battery charging and discharging.
2.2. System Connections:
2.2.1. Connect the Battery to the MSRx Battery Power connections
2.2.2. Connect the Battery to the MSRx Battery Voltage Sense connections
2.2.3. Connect the MSRx Temperature Sensor to the MSRx Battery Temperature Sense connections
2.2.4. Connect the PV Array(s) to the MSRx Array Input connections
2.2.5. Connect the Load to the MSRx Load Output connections
2.3. System Power On:
2.3.1. Turn on the Battery using whatever disconnect device is provided in the system
2.3.2. Ensure the Enable/Disable Link or Switch on the MSRx PSU/Load PCB Assembly (or MSRx
Interface PCB Assembly) is in the Enable position
2.3.3. Turn on each Array Input circuit breaker included in MSRx and externally (if fitted)
2.3.4. Turn on each Load Output circuit breaker included in MSRx and externally (if fitted)
