How It Works

The Smart Home Panel 2 acts as the control center for your entire home backup system. It features an automatic switch that seamlessly transfers your home to backup power in the event of an outage. The panel itself is made up of two sections: a distribution panel and a battery connection box. The distribution panel uses special switches, called relays, which you can control remotely to manage your backup system.

Versatility In Powering Your Home

The Smart Home Panel 2 is designed to work alongside your existing electrical system. It connects to your main electrical panel to access grid power when available. In addition to grid power, the Smart Home Panel 2 can also be connected to a generator through a special inlet box. This allows you to easily use your generator as a backup power source. The panel is intelligent and can automatically manage all of these power sources, including grid power, batteries, solar panels, and even a generator.

Smart Home Panel 2 Capacity

The EcoFlow Smart Home Panel 2 connects up to 3 sets of DELTA Pro 3 power stations (and each inverter supports up to 2 battery packs). The panel serves as an auxiliary distribution point for electricity from your home's main panel and provides extra breakers for your backup loads.

Monitor & Control At Your Fingertips

The EcoFlow smartphone application lets you track your energy use daily, monthly, and annually, and also manage system settings. This whole home backup system provides peace of mind during emergencies, power cuts, high energy demands, and more.

EcoFlow strongly recommends the EcoFlow Smart Home Panel 2 is installed by a professional EcoFlow-certified electrician.

DELTA Pro 3 Warranty

The EcoFlow DELTA Pro 3 comes with a 5-year warranty, with its LFP batteries lasting longer than 10 years with up to 4,500 cycles.
