In the transition toward energy independence, the ability to maintain power during a grid outage is the ultimate benchmark of a high-performance solar system. At Watts & Ergon, , we specialize in the technical components that bridge the gap between simple solar generation and true energy resilience.
An ATS is an intelligent electromechanical device that acts as the “traffic controller” of your electrical system. Its primary function is to sense the presence or absence of utility grid power and automatically switch the home or business load between the Utility Grid and the Backup Power Source.
| Type | Operation Mode | Best Use Case |
|---|---|---|
| Open Transition | Break-Before-Make | Residential / Non-critical loads |
| Closed Transition | Make-Before-Break | Hospitals / Data Centers |
| Static Transfer (STS) | Near-instant (<4ms) | Sensitive IT Equipment |
In a professional installation, the ATS often directs power to a “Critical Loads Panel.” This ensures that essential devices (lights, fridge, internet) stay on, while energy-heavy appliances (AC, EV chargers) are excluded to preserve battery life.
Our ATS solutions are designed for the harsh Middle Eastern climate. We provide:
