275 Gallon System
A larger reserve for your home.
Store up to 275 gallons of backup water with the McDowell Energy solar-powered system. A larger reserve gives your household more stored water for interruptions to your regular supply.
All of our water tanks are BPA-free.
Your larger reserve
More stored water. Ready for your home.
Our 275-gallon system uses a black, BPA-free, food-grade IBC tote protected by a galvanized metal cage. Its broad, rectangular shape holds a dedicated reserve of backup water on your property.
Five times the capacity of our 55-gallon drum. A full 275-gallon tank gives your household more water to draw from when your regular supply is interrupted. How long it lasts depends on the number of people in your home and how much water you use.
Solar energy, stored for later. A 100W solar panel charges the 12V lithium battery through a controller. The battery stores energy to power the pump after sunset as well as during the day.
Pressure when your home calls for water. The 55 PSI on-demand pump draws from the tank when a fixture or appliance needs water, helping conserve stored energy between uses. The discharge hose connects through a compatible exterior spigot to supply your existing plumbing.
This larger system suits customers who prioritize stored water capacity over portability. We can discuss placement and the connection to your home before installation.
Each system is hand-built in Central Florida. The $4,400 unit price includes installation, free delivery anywhere in Florida, and a 2-year warranty.
