Description
Flexible Home Backup Kit for Essential Circuits
The Home Backup Kit offers two transfer switch options: a Reliance Controls Pro Tran® 2 Series 30A, 6-circuit manual transfer switch with L14-30/L5-30 inlet, or a 50A, 10-circuit manual transfer switch with an SS2-50R inlet. Both models feature integrated wattmeters for easy monitoring. These switches pair with EcoFlow DELTA Pro, DELTA Max, DELTA 2, or dual DELTA Pro Ultra units to create a simple and dependable home backup power setup. Installation must be performed by a licensed electrician, who will connect either 6 or 10 selected circuits from your home’s breaker panel.
Stay Prepared for Power Outages
Choose key household circuits. such as refrigerators, lighting, garage door openers, and living-room outlets. to keep your home comfortable and protected during outages. For the most robust backup performance, EcoFlow recommends pairing the system with the DELTA Pro portable power station.
Simple, Plug-and-Play Backup Power
Build a customized backup solution that keeps your essential circuits running during blackouts. The system combines the DELTA Pro, transfer switch, and compatible power cord for a straightforward and reliable home power configuration.
Safe Backup Power for Sensitive Electronics
The transfer switches are cULus 1008 Listed, ensuring a safe and compliant backup option for household appliances. They support any UL-listed 1" interchangeable circuit breaker and can be field-reconfigured to accommodate multiple double-pole circuits when needed. A protective swing-up cover gives the installation a clean, finished appearance.
A Clean and Quiet Alternative to Gas Generators
Enjoy silent, fume-free backup power, ideal for both indoor and outdoor use. Unlike gasoline generators, EcoFlow battery systems require no fuel storage, produce no emissions, and can be recharged using solar power during extended outages.
Power Cord Requirements
