Installation Guide and User Manual for Sol-Ark 12K-2P-N Residential Hybrid Inverter

Quick Guide from the Manual

The Sol-Ark 12K-2P-N is a residential hybrid inverter designed for 120/240V split-phase systems. Before operating, verify utility voltage and ensure the unit is programmed for 120/240V Split-Phase at 60Hz. The system requires at least one power source (Battery, PV, or Grid) to turn on. Only qualified persons should install this equipment due to high life risk from fire or electrocution.

Installation

Mount the inverter in a location with at least 2 inches of vertical clearance and 6 inches of side clearance for heat dissipation. Protect the LCD screen from direct UV exposure. Use appropriate anchors for the mounting surface (concrete, wood, or metal frame).

Battery Integration

The system is a 48VDC nominal system. Connect batteries in series/parallel to maintain a range of 43VDC to 63VDC. Ensure battery breakers are OFF during wiring. Install the included toroids on battery conductors.

PV and Generator Connection

The inverter features 2 independent MPPTs, each supporting up to 2 PV strings. Max input voltage is 500VDC. Generators can be connected to the "GEN" input (for units <9.6kW) or "GRID" input (for units >9.6kW). Ensure proper phase sequence and use CT sensors for grid-tied or peak-shaving applications.

User Interface and Setup

The LCD touch screen provides access to system status and configuration. Key menus include:

• Basic Setup: Configure brightness, time, and system modes.
• Battery Setup: Define battery capacity, charge/discharge limits, and battery type (Lithium/Lead Acid).
• Limiter: Configure work modes such as Grid Sell, Limited Power to Home, and Limited Power to Load.
• Grid Setup: Adjust grid mode (General Standard, UL1741, etc.), frequency, and voltage parameters.

Parallel Systems

For parallel operation, all units must share a single battery bank and have the same software version. Assign one unit as "Master" (Modbus SN: 1) and others as "Slave" (Modbus SN: 2-9). Use the DIP switches on the inverter to configure the parallel setup.

Remote Monitoring

The MySolArk platform allows for remote monitoring and configuration. Connect the Wi-Fi/Ethernet dongle to the inverter and follow the setup instructions in the app to create a plant and configure network settings.

Troubleshooting

If the system encounters issues, check the "System Alarms" menu. Common error codes include:

• F15/F18/F20: Overload or overcurrent faults.
• F26: Bus Unbalance fault.
• F63: Arc Fault (check PV connections).
