LoadShedder Prebuilt

The LoadShedder Prebuilt is a smart power detector that turns off appliances like geysers and pool pumps when load shedding starts.

Furthermore, the LoadShedder Prebuilt automatically deactivates appliances such as geysers and pool pumps when load-shedding events occur. This user-friendly device is a prebuilt alternative to the original LoadShedder, which simplifies installation by requiring installers to connect it to the inverter and Eskom feed. Please note that the Load Shedder serves as a signal device and is used to trigger other Sonoff devices, such as the Sonoff Geyser unit, through eWeLink scenes on the app. Furthermore with the Load Shedder, you can effortlessly manage your energy consumption and contribute to more efficient use of power during load-shedding periods.

**Please Note this is pre-built for ease of installation**

We field-tested this unit for over a year across multiple sites and were very pleased with its success and reliability. However, correct installation of the LoadShedder complements any and all inverter systems.

Furthermore the LoadShedder automatically shuts down devices such as pool pumps, geysers, dishwashers, and any home automation devices that you deem non-critical to preserve battery power.

You do not need to re-wire the DB board additionally. All appliances that need to be controlled require smart devices such as Sonoff Basic or any other Sonoff products.

Full integration into other smart home platforms such as Smart Life, Samsung Smart Things, and Top 20 brands is possible. This is fully cross-platform designed via IFTTT.

Certified installers, electricians, and solar installers are the target audience for this product.
