Whether you’re concerned about home energy security, need reliable off-grid portable power, or are looking to save money on electricity bills, EcoFlow solar generators can provide enough electricity for a road trip or run your whole home. EcoFlow RIVER 3 Plus provides UPS backup for computers in your home office and is compact enough to fit in your backpack. EcoFlow DELTA Pro 3 and DELTA Pro Ultra provide enough AC output, battery storage capacity, and solar panel input to power almost any home. EcoFlow’s whole-home backup generators offer multiple options for generating and storing electricity, including solar panels, gas, propane, or inverter generators, household (AC) power, 800W alternator charging, and more. Once you achieve solar payback, money saved on bills is money earned. Because there are no ongoing fuel costs, solar generators offer much better ROI than gas generators, especially over the mid-to-long term.

All solar panels or other PV modules that generate electricity from sunlight use the photovoltaic (PV) effect. Today, over 90% of solar panels are made with multiple polycrystalline or monocrystalline photovoltaic cells, which harvest photons from visible light and convert solar energy into DC electricity. In grid-connected solar power systems, a solar inverter converts DC into AC (household) electricity for immediate consumption or transmission to the utility grid. Off-grid and hybrid solar systems — like EcoFlow DELTA Pro 3 — direct DC power from PV modules through a charge controller for storage in a solar battery, and the inverter converts DC to AC for immediate use.

Solar generators are safe, especially compared to traditional fossil fuel generators. They don't emit deadly gases like carbon monoxide or use flammable fossil fuels to generate power. Solar generators use the photovoltaic cells in solar panels to absorb sunlight and convert the energy into DC electricity. The DC power is stored in a state-of-the-art battery and converted to AC (household) electricity on-demand for immediate use. Unlike gas generators, you can operate solar generators inside your home. Since they’re whisper quiet, you can even run one in a bedroom, and it won’t disturb your sleep.

A solar generator is an all-in-one solution for storing the electricity generated by PV modules like portable or mountable solar panels. For example, EcoFlow DELTA series solar generators have all of the necessary balance of system components for residential solar power built in, including a charge controller, solar inverter, solar battery, and advanced battery management system. Off-grid and hybrid solar systems require the above components to operate. On-grid solar panel systems only require a solar inverter, but grid-tied solar panel systems don’t work during blackouts. They shut down automatically and remain offline for the duration of any power outage.

Yes. A whole-home solar generator like EcoFlow DELTA Pro Ultra offers enough AC output and modular storage to power almost any home during extended power outages. With up to 90kWh of LFP battery storage, 21.6kW of AC output, and a maximum solar charge input of 16.8kW, you have the option to live completely off-grid indefinitely. To determine what size solar generator you need to run your home, calculate the total energy usage requirements of appliances you want to operate simultaneously. Don’t forget to factor in starting watts (surge power) — a requirement for starting many large appliances. Next, determine your battery storage capacity (kWh) and electricity generation goals, factoring in peak sunlight at your location. As long as the AC output and storage capacity are sufficient to meet your household needs, a solar generator and PV modules with a combined rated power wattage that’s enough to keep the solar battery charged can power your whole home.

There are two primary factors to consider when sizing a solar generator to run a fridge, freezer, air conditioner, or other appliances — especially those that require a motor. First, determine the starting and running wattage of the refrigerator. Fridges require a short burst of surge power to turn on. Otherwise, they won’t work. Traditional gas generators offer very little (if any) surge power above their operating wattage. Fortunately, EcoFlow’s solar generators — like DELTA Pro 3 — provide double their AC output as surge power to get fridges and other large appliances up and running. DELTA Pro 3 has an AC output of 4000W/6000W X-Boost/8000W starting watts. More than enough to start and run refrigerators and multiple other high-wattage appliances at once. Thanks to proprietary X-Boost tech, it can run up to 6000W of appliances simultaneously, 50% above its continuous AC output.

If you live in a location that receives more than 3 or 4 hours per day of peak sunlight, a solar generator likely beats a gas generator for home by every metric except price. Despite the higher upfront investment, solar generators have no ongoing fuel or maintenance costs. Once you achieve solar payback, you start making money by saving on electricity bills. Solar generators also offer up to double the starting power of gas generators, making them ideal for high-wattage appliances. Over the mid-to-long term, solar generators offer a much better return on investment than gas. Additionally, incentives like the Federal Solar Tax Credit can save US taxpayers 30% on the total purchase and installation costs of an eligible system, like EcoFlow DELTA Pro 3 or DELTA Pro Ultra.

Solar generators come in all shapes and sizes. You can take an EcoFlow RIVER Series solar generator and 125W bifacial modular solar panel backpacking or use one of the EcoFlow DELTA Pro series for whole-home backup. Size may refer to the dimensions and weight of the product — essential considerations for portability — or AC output (watts/kilowatts) and battery storage capacity (watt-hours/kilowatt-hours). Carefully consider your use case and how much power vs. portability you need. EcoFlow has a wide selection of portable power stations and solar generators to meet almost any need — from backpacking to powering an entire home off-grid.
