Sol-Ark SA-8K 8.0kW Battery-Based Hybrid Inverter (SA-8K-2P)

The Sol-Ark SA-8K (SA-8K-2P) is a powerful and versatile all-in-one hybrid inverter designed for residential and light commercial applications. Capable of operating with or without batteries, this 8,000W unit supports grid-tie, off-grid, and battery backup configurations with seamless integration of solar, battery, grid, and generator power sources.

Key Features & Benefits

• Flexible Operation Modes: Supports grid-tie (sell power back to utility), off-grid, zero export, time-of-use, and meter zero modes—providing complete control over energy management.
• Battery or Battery-Less Operation: Can function as a standard grid-tie PV inverter without batteries, or add batteries at any time for backup power and energy shifting.
• Dual AC/DC Coupling: Accommodates both DC-coupled solar (for high efficiency) and AC-coupled solar (for retrofitting existing systems), offering maximum design flexibility.
• Dual MPPT Charge Controllers: Features two MPPT trackers with 150–425V operating range and 18A per tracker, supporting up to 11,000W of total PV input power.
• Integrated Safety Features: Built-in Arc Fault Circuit Interrupter (AFCI), Ground Fault Detector Interrupter (GFDI), and rapid shutdown capabilities—eliminating need for external safety components.
• Dual AC Inputs: Supports both grid and generator connections with automatic transfer (4ms transfer time) for reliable backup power.
• Battery Temperature Sensor (BTS) Included: Ensures optimal charging and extended battery life by monitoring battery temperature.
• Rugged IP65/NEMA 3R Enclosure: Suitable for indoor or outdoor installation, protecting against rain, sleet, and snow.
• UL1741-SA (Rule-21) Certified: Compliant with advanced grid-support functions including volt/var, frequency-watt, and ride-through requirements—approved for California, Hawaii, and other Rule-21 states.
• Wi-Fi & LAN Monitoring: Built-in Wi-Fi and LAN hardware included for remote monitoring and system management.
