Controllers

Throughout this document, Controller refers the controllers listed below.

Controller	Controller types	Software version
iE 150	Battery, Solar	1.31 or later
ASC 150	Storage, Solar	1.30 or later
ASC-4	Battery, Solar	4.29 or later

Battery/Storage

The Battery/Storage controller allows interfacing to an energy storage system battery control unit, battery management system and/or power conversion system as a Modbus client. The controller can read operating values, and write control commands.

The Battery/Storage controller includes two DEIF Generic Modbus client protocols. See Battery/Storage: DEIF Generic protocols for more information.

Fastpath: See the iE 150 Battery ASC 150 Storage ASC-4 Battery Modbus client tables (an Excel spreadsheet) for the data schemes for the DEIF Generic protocols.

Solar

The Solar controller allows interfacing to inverters and conducting control as a Modbus client. Multiple inverter makes and models are supported. Note, however, that a controller can only control a system with one type of inverter. That is, the controller cannot be used with a mix of different inverters.

Fastpath: See the iE 150 ASC 150 and ASC-4 Solar Modbus client tables (an Excel spreadsheet) for the supported data and protocols for a Solar controller.

Note: The controller also includes a Modbus server. This is described in the iE 150 Battery Solar Modbus server tables, ASC 150 Modbus server User manual and ASC 150 Modbus server tables.
