Having a commercial energy storage solution offers tremendous advantages for cost savings and energy independence for critical businesses. The Sol-Ark 60K-3P-480V commercial hybrid inverter is a hybrid inverter designed to fulfill these needs with robust features for optimal performance and safety like rapid shutdown and NEC compliance. The Sol-Ark 60K complies with NEC requirements for PV systems with DC conductors and energy storage solutions.
Importance of Rapid Shutdown in Commercial Hybrid Inverters
Section 690.12 of the NEC mandates rapid shutdown for all PV systems to reduce shock risks for emergency responders while protecting property and critical infrastructure. This regulation also minimizes damage to expensive equipment, especially in the commercial sector. As systems grow larger and more complex, the ability to quickly and safely de-energize high-voltage conductors in a PV system supports the continued expansion of renewable energy installations.
60K-3P Commercial Inverter Emergency Stop Initiation
The Sol-Ark 60K hybrid inverter includes a built-in emergency stop initiation that meets NEC rapid shutdown requirements and integrates with rapid shutdown products. In the user wiring area of the Sol-Ark inverter, a sensor pinout board features pins 9 and 10 to initiate the emergency stop. An E-stop button connects to these pins through a NO dry contact relay. When the E-stop button closes, the inverter opens grid/gen relays, shuts down voltage on the load output, and disables the 12Vdc RSD supply. This voltage loss initiates rapid shutdown for all PV connected to the 60K inverter. The NEC Code requires a single shutdown switch, and this wiring approach ensures compliance.

60K-3P Inverter Arc Fault Detection
Section 690.11 of the NEC requires PV systems with DC circuits ≥80V to include a PV arc-fault circuit interrupter. When the system detects an arc fault, it must shut down and display a visual indication. The Sol-Ark 60K inverter meets NEC 690.11, protecting the PV system, infrastructure, and human life. A fault code appears on the interface screen, logs in the error history, and displays on the MSA monitoring platform. If the system detects an arc fault, a manual restart becomes necessary, allowing a proper system inspection before re-energizing. By integrating these critical safety features, the Sol-Ark 60K inverter delivers compliance, reliability, and peace of mind for commercial solar installations.
The Sol-Ark 60K-3P hybrid inverter excels as a top-tier commercial energy storage solution by combining cutting-edge safety features, NEC compliance, and superior performance. Its built-in rapid shutdown capabilities, emergency stop initiation, and advanced arc fault detection offer unparalleled protection for businesses. Choosing the Sol-Ark 60K means investing in a reliable, future-proof system that supports commercial energy needs with efficiency and peace of mind.
