Why You Need An Ecoflow Delta Battery Powered Generator

  • Lightweight & Compact Design- Compared to gasoline generators, battery generators are more compact and lightweight. A lightweight lithium battery pack and solar panel input make this portable solar generator easy to move around.
  • Safely Use Indoors - Gasoline generators are loud and emit carbon monoxide, which causes more than 500 deaths annually. During power outages or home recreational activities, you can safely use your Ecoflow DELTA  Pro portable power station indoors.
  • Save Time & Money - Maintaining a gasoline generator is expensive and time-consuming - typically maintained semi-annually at a cost of $150 per year. Battery-powered generators require no maintenance. Portable solar panels mean harnessing the free power of the sun and leaving fossil fuels in the ground.

For the past two years, EcoFlow has dedicated precious time and energy to creating the X-Stream Recharge Technology. This technology provides the fastest recharge rate on the market, working 10x times faster than competing brands of battery-powered generators. Lightning-fast charging outputs allow the DELTA Pro to be fully recharged in under two hours using any regular wall outlet.

The world’s fastest charging portable power station.

Get record-breaking speeds at 6500W with the MultiCharge feature.

    A Brief Overview of the U.S. Home Energy Tax Credit

    Discover the financial advantages of the U.S. federal solar tax credit for homeowners considering installing a solar system in their main residence. This incentive provides a 30% discount on the current cost of a solar system. If you've set up a system in 2022, it's advisable to speak with your tax consultant to see if you're eligible for a higher credit rate.

    Understanding the U.S. Federal Solar Tax Credit:

    This tax credit is tailored for homeowners and applies to solar systems installed in primary homes. The credit covers a percentage of qualifying expenses, and thanks to the recent Inflation Reduction Act, the scope of the Investment Tax Credit (ITC) has broadened. Solar systems installed from 2022 to 2032 are eligible for a 30% tax credit, which will drop to 26% in 2033 and 22% in 2034. There's no cap on the amount you can claim.

    What Expenses Are Eligible:

    Qualifying expenses include solar photovoltaic panels, attic fan power systems (except for the fan itself), labor costs for installation and setup, balance-of-system components, and applicable sales taxes. Standalone batteries with a capacity of 3 kWh or more may also be eligible! For instance, if the solar system you initially purchase includes a single battery with a capacity of less than 3 kWh, but you also buy extra batteries during the installation process that bring the total capacity to more than 3 kWh, then the entire setup may be eligible for the tax credit.

    How to Determine Your Eligibility:

    To confirm your eligibility for this federal solar credit, review the guidelines set forth by the U.S. Department of Energy and consult your tax advisor.

    Steps to Claim the U.S. Federal Solar Tax Credit:

    1. Verify Eligibility: Speak with your tax advisor to confirm your eligibility and to understand how to make the most of the credit.

    2. Fill Out IRS Form 5695: This form, available online, is specifically for claiming renewable energy credits. Guidelines for completing the form are provided.

    3. Apply Credits on Your 1040: Use the total credit amount from Form 5695 to lessen your tax liability on your Form 1040.


    Always consult your tax expert to fully understand your eligibility for tax credits based on your unique situation.

This resource should not replace professional tax or financial advice and should not be the only factor in your purchasing, investment, or tax choices.
