User Manual for Sol-Ark 5K, 8K, 12K, 15K Inverter

Quick guide from the manual

This document provides instructions for integrating Sol-Ark 5K, 8K, 12K, and 15K inverters with Pytes E-BOX batteries. It covers physical cable connections, communication setup, and software configuration required for the system to operate correctly.

Connecting Cables

Proper cable sizing and communication connections are essential for system safety and performance.

• Power Cables: Use 4/0 gauge power cables for the Sol-Ark 15K model. Use 3/0 gauge power cables for the 8K and 12K models. Connect these between the inverter and the battery or busbars.
• Communication Cables: A standard ethernet cable is used for communication between the inverter and the Pytes E-BOX battery, as the pin assignments are compatible.

DIP Switch Settings

Before connecting communication cables, configure the DIP switches on every master battery. Refer to the specific DIP switch diagram provided in the manual to ensure the correct switch positions are set.

Programming the Inverter

Once the physical connections are made, configure the inverter settings via the touchscreen interface:

1. Press the gear icon on the top right of the screen.
2. Select the Battery Setup menu.

Battery Parameters

In the Battery Setup menu, configure the following parameters:

• Batt Capacity: Set to 100Ah per unit.
• Max A Charge/Discharge: For 8K/12K models, the max is 185A. For the 15K model, the max is 275A. Enter the lower value of either the inverter's max amps or 50A multiplied by the number of battery units.
• Settings: Select Use Batt% Charged.
• BMS Lithium Batt: Enable this and set the value to 00.
• Activate Battery: Turn this setting ON.

Note: Enabling BMS Lithium Batt 00 will automatically adjust and lock certain values (like temperature coefficients). Ignore these locked values as the BMS is in control.

Charge and Discharge Tab Configuration

Navigate to the Charge and Discharge tabs within the Battery Setup menu to configure operational limits:

Charge Tab

• Start%: 15%
• A: Same as the Max A Charge value set in the Battery tab.
• Float V: 55.6V
• Absorption V: 56V
• Equalization V: 56V

Discharge Tab

• Shutdown: 10%
• Low Batt: 20%
• Batt Empty: 47.5V

Confirming Communication

After programming, verify that the inverter and battery are communicating. Successful communication is indicated when battery data appears in the header section of the system setup screen.
