Solar High Water Warning System

The SLD Solar High Water Warning System is designed to reduce risk in flood-prone areas by monitoring rising water levels and activating visual and or audible alerts once a preset height is reached. A remote water level sensor is installed safely above the high water line and accurately measures water levels without making physical contact with the water, preventing damage from debris. Each off-grid unit is powered by a high-quality solar powerbank and control module mounted near the sensor. When one system is triggered, multiple connected systems at different locations can be activated simultaneously via a wireless connection.

Solar High Water Warning System FAQs

The Solar High Water Warning System operates by detecting the water level triggering an alarm and/or wirelessly connected solar sign faces at a preset water level

Our Solar High Water Warning Systems do not require specialist skills or tools to install; we provide comprehensive written installation instructions to ensure a smooth system roll out

No, the Solar High Water Warning System is an entirely off grid solar system requiring no connection to the grid. There are also no wired connections between the system on either side of the water course, each system is connected wirelessly with an operational distance of > 300Mtrs.

The word for this is “Autonomy”. We build the Solar High Water Warning System after confirming operational load the system will be under. We calculate how many times the system would be interacted with in 24 hours on the shortest day of the year to use as a base line. From there we use shadow mapping to evaluate the recharge capacity on this day to ensure we deliver a Solar High Water Warning System that carries a minimum of 72 hours autonomy with no solar recharge.
