Solar Battery

Yes, it’s compatible with existing solar systems, including rooftop solar*. For each EcoFlow DELTA Pro Ultra Inverter, solar input can reach a maximum of 5600W (16.8kW with 3 inverters) with the following:High voltage PV: 80-450V, 15A, 4000W MaxLow voltage PV: 30-150V, 15A, 1600W Max*If you connect the EcoFlow DELTA Pro Ultra to PV system circuits installed on or in buildings, according to NEC regulations, the system shall include a rapid shutdown function to ensure operation safety and reduce shock hazards for emergency responders. If you wish to connect the EcoFlow DELTA Pro Ultra to PV system circuits, a pre-purchase consultation must be completed by a qualified electrician or installer.

Charging priority: low voltage photovoltaic > high voltage photovoltaic > 5 + 8 interfaces (including Smart Home Panel 2) > mains

Yes. EcoFlow DELTA Pro Ultra (Inverter + Battery) works as a standalone unit powering electrical appliances of up to 7200W. There are 11 outlets on the inverter, including NEMA 5-20, TT30, L14-30 supporting 30A, USB-C, and USB-A.

The fastest charging power for one battery is 6200W. It takes about 92 minutes to charge one battery from 0% to 100%, but if stacked on two or more batteries, the maximum charging power can reach 8800W. It takes about 1 hour and 56 minutes to charge two batteries from 0% to 100%.

You can easily install household solar power batteries if you buy an all-in-one solar generator or portable power station with solar panel charging inputs. If you’re retrofitting or installing a grid-connected solar power system with battery storage, you must work with a professional installer and/or a licensed electrician. If you want to integrate a solar inverter and battery with your home circuitry, you must hire an electrician to install the transfer switch.

Yes. If you purchase a solar battery with sufficient storage capacity to operate high-wattage appliances like refrigerators and HVAC systems during non-daylight hours, you can run your home all night. Determine the starting and running wattage of the appliances you want to run at night (total watts/kilowatts) to ensure the system provides enough AC output. Estimate the electricity generation from solar panels at your location. Ensure your PV array can generate enough electricity to charge the battery during the day — or tap into grid power to make up any shortfalls.

It depends on the application. If you want a solar battery for off-grid adventures like camping, portability is likely a bigger concern than storage capacity. If you’re purchasing a solar battery for your house, ensure that the AC output of the system in watts/kilowatts is sufficient to start and run the appliances you want to operate simultaneously. Then, determine how long you want to run your appliances with home battery storage in watt-hours/kilowatt-hours (kWh) before recharging. For example, how many hours of backup without grid power during a blackout or without electricity production from solar panels at night?

The essential factors to consider when choosing solar battery storage are capacity, cycle life, charging methods and speeds, safety, and durability. Chemistry plays a significant role, with LiFePO4 battery providing superior performance and longevity compared to lead-acid batteries. If you’re purchasing solar panels and a battery for your home, portability may not be a concern, but it can be crucial in some applications. It’s also essential for your solar inverter to output enough power (watts/kilowatts) to start and run your appliances and home systems like HVAC.

Not necessarily. It depends on the application. For example, if you’re taking a portable power station fishing, you’ll want a much smaller solar battery than you would for home backup. There’s also no point in paying for more storage capacity than you need. The best way to size a solar battery is to total the wattage of the devices you want to run simultaneously (watts/kilowatts) and how long you want to run them between charges (watt-hours/kilowatt-hours). Simple calculations empower you to purchase the solar battery you need.
