Setting Up Sol-Ark Open-Loop Configuration

As a precautionary measure, it is recommended to program the Sol-Ark inverter with the correct voltage-based open-loop parameters before setting up closed-loop parameters.

If necessary, first configure Sol-Ark inverters to operate in parallel by establishing the inverter master/slave relationships and phase designations before setting the parameters for battery operation. Configuring the master inverter will cascade parameters and settings to the slave inverters.

The Open-loop Configuration Procedure

Refer to the latest Discover Energy Systems documentation for battery values and the latest Sol-Ark documentation for details on menu navigation and the setup procedure.

Set the Discover Lithium batteries to ON and set the inverter to ON.
Using the touch screen and keypad on the inverter, navigate from the SYSTEM SETUP menu to the BATT SETUP menu screen.
Enable and disable parameters according to the instructions in the tables below.
Set each variable parameter according to the instructions in the tables below.
Touch the OK button to save all onscreen values - Ignore data displayed in GREY boxes.

NOTE

Touch the Sol-Ark screen to:

Navigate the Sol-Ark onscreen menus.
Enable parameters.
Activate the adjustment of values.
Save all onscreen settings.

Values are adjusted using the keypad.

NOTE

Enable parameters with a CHECKMARK, and disable parameters by leaving them unchecked. Touch a WHITE box onscreen to activate the adjustment of that value. Selecting parameters that have been enabled and disabled alters values that are available to be adjusted.

A WHITE BOX indicates values that can be adjusted.
A GREY BOX indicates values that cannot be adjusted, and any data displayed should be ignored.

NOTE
If necessary, configure Sol-Ark inverters to operate in parallel before setting the parameters for battery operation.
