The customer is inquiring about the DC input of the P280 model, specifically whether two connectors can simultaneously connect to two photovoltaic panels with different voltages.

The P280PV features dual XT90 input ports. Each PV input supports a maximum power of 600W, an input voltage range of 11.5–55V, and a maximum input current of 20A. Any solar panel with an open-circuit voltage within the P280's input voltage range is compatible.
