A homeowner shared on Reddit that two solar-connected Anker Solix F3800 Plus power stations have cut their grid use by 30 kilowatt-hours per day.
On a post in the r/AnkerSOLIXCommunity, the homeowner shared that they are “already seeing huge savings” on their electric bills thanks to their solar-connected setup. 
Rather than building the system all at once, they said they are expanding in stages. They are running 1,600 watts of solar to one expansion battery, and they are planning to purchase another to align with the double hub manual.
“Nice savings,” one commenter praised
The original poster replied, “Thanks. It’s only a start.”
As this homeowner discovered, battery storage is one of the best ways to rely less on the electric grid and protect your home during outages. If you’re curious about your own options, it may be worth exploring EnergySage’s free tools for home battery storage information.
A reduction of 30 kWh per day can translate into meaningful savings, particularly in areas with high electricity rates or time-of-use pricing. With battery storage, a solar-equipped household can depend more on its own energy instead of pulling all its power from the grid.
And unlike solar panels alone, batteries can keep stored electricity available after sunset or when the grid goes down. They can also be helpful during peak energy periods when electricity can be more expensive to use.
