A homeowner looking to use solar power for a commercial dehumidifier is learning that even one appliance can draw a significant amount of electricity. One commenter estimated that keeping the unit running continuously would use about 18.2 kilowatt-hours per day.
What to know
The homeowner shared in Reddit's r/solarDIY community that the first device they want to run with their 48-volt solar setup is a Vevor 156-pint commercial dehumidifier.
They were trying to decide between buying individual components and purchasing an Amazon kit priced in the $2,000 to $5,000 range. A commenter estimated the dehumidifier's power use at 759 watts, making runtime a key factor in selecting the right system.
Going solar is one of the best ways to reduce home energy costs, and solar leases can offer hundreds of dollars in monthly savings without any upfront expense. Homeowners can use EasyHome's free explorer tool to check potential savings from vetted installers in their area.
Additional context
Beyond powering the dehumidifier, the homeowner also plans to expand the system in the future. A commenter pointed to an Eco-Worthy home-backup package with a 5.12-kilowatt-hour battery setup that costs around $1,500.
"Not a bad kit for around $1500, and you can expand it later as needed with additional batteries and inverters," the commenter wrote.
For homeowners considering a broader energy setup, EasyHome also helps compare backup battery storage options. Pairing solar with a battery can help homeowners maximize savings and keep power available when the grid goes down.
