EcoFlow DELTA Pro 3 has two PV input ports, which are for high-voltage PV port and low-voltage PV, respectively.High-voltage PV: 30-150V, 15A Max, 1600W Max. Low-voltage PV: 11-60V, 20A Max, 1000W Max.The maximum solar input for the EcoFlow DELTA Pro 3 is 2600W. Please note that this value is based on experimental results under optimal conditions. Achieving this maximum input may require the use of higher-power solar panels that are within the product’s voltage tolerance but exceed the PV port’s power limit. Actual solar input performance can vary depending on the solar panels used, environmental factors, and system configuration. For more information on designing your own solar setup, please contact EcoFlow Customer Service. Before performing any installation, please ensure that it is carried out by a qualified and certified professional.
