The Challenge Mark Faced
Mark lives in Texas with his family. His two-story home relies heavily on electricity. Two air conditioning units, an electric dryer, an electric vehicle, work-from-home setups, and growing kids meant that energy use was constant and unavoidable.
One experience became the defining challenge.
A fragile grid that failed when his family needed it most: In the winter of 2020, Texas experienced a historic freeze. Mark’s family lost power for five days while temperatures outside dropped to 5°F. Inside, the house hovered near freezing. With no electricity, his family endured one of the most stressful weeks they had ever faced. That moment fundamentally changed how he thought about energy security.
High and rising electricity bills that limited comfort: During the summer, Mark’s power bills regularly reached $400. When he once tried to keep his home at a truly comfortable temperature of 72 degrees, the bill jumped to $500–$600 a month. To control costs, he kept the thermostat at 78, sacrificing comfort to avoid higher bills.
After living through both extremes, Mark wanted a system that could protect his family during outages and give him freedom from high electricity costs.
Why Mark Turned to EcoFlow
Mark had followed solar technology for more than a decade, but rising electricity prices finally made the decision unavoidable. Over roughly ten years in Texas, his electricity rate increased from about $8/kWh to $18/kWh, more than doubling. Using detailed spreadsheets, he calculated that a solar and storage system with a long warranty would deliver a worthwhile return on investment.
When comparing options, Mark focused on outcomes rather than familiarity. He wanted whole-home backup for extreme weather, the ability to run two AC units at the same time, and long-term cost protection. EcoFlow OCEAN Pro stood out as a bold but rational choice. Although newer to large residential systems in the U.S., EcoFlow had already deployed large-scale systems internationally and offered a 15-year warranty aligned with his ROI calculations.
For Mark, EcoFlow represented a system built not just for today’s bills, but for the next 20 to 30 years of rising energy demand.
The EcoFlow Solution
OCEAN Pro delivered the technical foundation Mark needed to achieve those goals.
Whole home power without hesitation: The system’s 24 kW inverter provides enough continuous output to support his entire home. It can start heavy loads like 2 5-ton HVAC units at the same time and switch power sources in under 10 milliseconds, keeping everything running seamlessly.
Energy storage that turns solar into real control: With battery storage paired to solar, Mark can store energy during the day and use it when electricity prices are highest. This allowed him to take advantage of a plan with free overnight power while avoiding expensive daytime rates that can reach 35 to 40 cents per kWh.
A smart app that makes energy understandable: The EcoFlow app gives Mark real-time visibility into generation, storage, and usage. He can see exactly how much power his home is drawing and how the system responds under heavy load. After installation, when a firmware error appeared, his installer was able to view the same data remotely, guide a restart, and resolve the issue quickly. The system has run smoothly ever since.
The Results That Changed Everything
The installation of OCEAN Pro changed everything.
Zero-dollar energy bills: Within the first month, Mark saw a $0 power bill. For someone who tracks ROI carefully, that moment confirmed the decision. Every month of operation increases the return on his investment.
Comfort without compromise: Mark no longer worries about running the AC. He keeps his home at a comfortable temperature even during Texas summers and no longer thinks twice about electricity use.
Peace of mind during outages: With whole-home backup in place, Mark knows his family will not relive the fear of extended outages during extreme weather.
