Installation and User Manual for Sol-Ark 15K Outdoor Inverter

Quick Guide from the Manual

The Sol-Ark 15K Outdoor is a high-capacity solar inverter. Before installation, ensure the unit is mounted in a location protected from direct sunlight with at least 2 inches of clearance on the sides for cooling. Qualified persons only should perform the installation due to high-voltage risks. Always verify that the system is properly grounded and that the neutral is bonded to the ground only once in the circuit.

Inverter Components

The unit features an LCD touch screen for programming, a PV disconnect switch, and an ON/OFF button. Key connection areas include the 250A battery breaker, communication ports, MPPT inputs, and terminal blocks for Grid, Load, and Generator connections.

Physical Installation

Mount the inverter using the provided French Cleat. Ensure the unit is level. When connecting batteries, use the included toroids on battery input cables. The system is a 48V nominal system; do not exceed 4 batteries in series for 12V units. Always use strain reliefs on all wires entering or exiting the user area.

Wiring Diagrams

The manual provides specific wiring diagrams for various configurations, including standard 120V/240V systems, off-grid setups, and AC-coupled systems. Ensure all AC wires use conduit or double-insulated wire. CT sensors must be installed on L1 and L2 upstream of the main service panel for features like Peak Shaving and Limited to Home mode.

Programming and GUI

The LCD touch screen allows for comprehensive system configuration. Key menus include:

• Basic Setup: Adjust brightness, time, load limit power, and parallel system settings.
• Battery Setup: Configure battery capacity, charge/discharge rates, and charging voltages (Bulk, Absorption, Float).
• Grid Setup: Configure grid frequency, grid type, and power modes (Limited Load, Limited to Home, Grid Sell, Time of Use).

Generator Integration

The Sol-Ark 15K supports generator integration via the GEN terminal block. For generators <10kW, use the GEN breaker. For standby generators >10kW, use the GRID breaker. Ensure the generator has two-wire start compatibility for automatic generator start (AGS) functionality.

Troubleshooting

If the system displays an error, consult the error code table. Common issues include:

• LCD not powering on: Check all power source connections (PV/Grid/Battery).
• Grid Phase Wrong: Indicates a wiring issue; verify L1/L2 connections between Grid and Load breakers.
• System beeping: Check the alarms menu; if no battery is connected, ensure 'No Battery' is selected in settings.
• Panels not producing: Check PV disconnect switch and ensure PV voltage is within 150V-425V.

Maintenance and Warranty

Regularly check the system using the Install Verification Checklist. The unit comes with a 10-year limited warranty. Returns require a Return Material Authorization (RMA) number. Contact Sol-Ark support at 1-972-575-8875 or [email protected] for assistance.
