Soltaro (4.5kWH + 5kWH) batteries with Synapse 5.0k+ inverters - managed

Ensuring smooth operation and correct configuration

Summary:

This application note includes all procedures to follow to ensure reliable and effective operation between a Soltaro battery and Synapse inverter. This system is classified as a “managed” system as all battery behaviour is communicated via a communication cable.

Overview:

It is recommended that the following are considered before commissioning such systems:

• All cables are correctly terminated, i.e. Rj45 crimps and battery power cables.
• System is correctly sized according to the recommended maximum charge / discharge rates of these batteries:

Max charge / discharge rates:

4.5kWH = 90A at 1C

5kWH = 100A at 1C

Specific technical details:

The following is the correct wiring for the communications between a Synapse 5.0K+ and the Soltaro battery:

Additional information:

• Before the collection of system components from Rubicon, please ensure that your battery has been pre-programmed by the technical support team.
• During the commissioning stage of the installation, ensure that your battery type selected is set to “SOL”.
• Common errors which could occur:

“Error 61” – Loss of communication between battery and inverter. Ensure the communication cable is inserted correctly.

“Error 69” – BMS message due to incorrect charging. Please contact the technical support department.

• NOTE: Once effective communication is established between the inverter and battery, the battery icon on the display will flash. Once this occurs, you will not be able to change any voltages or currents on the system.
