Over Voltage Protector

STATS-04 3-Way ATS Automatic Transfer Switch with Triple Voltage & Output Current Display

The Soltree STATS-04 is designed for engineers and facility managers who need to know not just which power source is active, but how much current their load is actually drawing at any given moment. Its 4-parameter display adds real-time output current to the three input voltage readings, eliminating the need for a separate clamp meter or sub-meter to track load behavior during source transfers and normal operation.

This makes the STATS-04 the preferred choice over the STATS-03 in applications where load current data drives decisions: generator sizing verification, electrical contractor commissioning of new panels, rental property sub-metering with ATS, solar storage systems requiring load-vs-generation balance monitoring, and industrial installations where overcurrent trending helps predict maintenance needs before a trip occurs.

When a fault is detected on the active source — voltage outside the 130–300V over-voltage or 80–210V under-voltage window, or current exceeding the configured threshold — the STATS-04 switches to the next available source in under 0.2 seconds. Priority sequence is customizable, and startup and recovery delays (each 1–600s) are independently set. Available in 63A, 80A, and 100A ratings on a 35mm DIN rail.

Key Features
