EcoFlow battery backup system in a home utility room

EcoFlow Complete — Backup Power System

When the power goes out, a gas generator is loud, requires fuel storage, and cannot be used indoors. EcoFlow Complete is a battery-based backup system that silently powers your essential loads without any fuel, fumes, or noise. It sits quietly in your utility room or garage and kicks in automatically when the grid drops.

EcoFlow Delta Pro Specifications

Capacity

3.6kWh base capacity, expandable up to 25.2kWh with additional battery modules. Enough to run critical loads for hours or days depending on configuration.

Output

3,600W continuous AC output with 7,200W surge. Powers heavy loads like well pumps, microwaves, and power tools without tripping.

Solar Input

Up to 1,600W solar input. Charge the battery from solar panels during the day and run your home off stored energy at night or during outages.

Chemistry

LiFePO4 (lithium iron phosphate) battery cells. 6,500 cycles to 80% capacity. Safe, stable, and long-lasting.

What It Powers

A single Delta Pro (3.6kWh) can power these essentials for 12+ hours during an outage:

With additional battery modules, you can extend runtime to cover well pumps, chest freezers, and even window AC units for extended outages.

Installation Options

Portable Setup

The simplest approach: keep the Delta Pro charged and plugged in. When power goes out, manually plug your essential devices into the unit. No electrician required, no permanent wiring. Good for renters or those who want flexibility.

Wired Transfer Switch

For permanent installations, we install a transfer switch that connects the Delta Pro to your home electrical panel. When the grid drops, the transfer switch automatically routes power from the battery to your selected circuits. No manual plug-swapping. This is the recommended setup for homeowners who want seamless backup.

Monitoring and Control

The EcoFlow app provides real-time monitoring of battery level, power input/output, and device status. You can see exactly how much power each connected load draws and set priorities for which circuits get power first during an outage.

For homes with Home Assistant, we integrate the EcoFlow unit into your existing dashboard. This means you can monitor battery status alongside your other smart home systems and create automations like starting solar charging when battery drops below 30%.

Pricing

$1,899 – $7,500 equipment + $95/hr install

Equipment cost depends on capacity and configuration:

Installation is billed at $95/hr for members. Transfer switch installation typically takes 3-5 hours. Solar panel installation is quoted separately based on roof size and orientation.
