EcoFlow TITAN 5kWh Extra Battery

EcoFlow TITAN 5kWh Extra Battery

Add 5,017.6Wh of lithium iron phosphate storage to your EcoFlow TITAN home backup system. One extra battery brings a compatible TITAN 5000 Classic, TITAN 5000 or TITAN 5000 Plus from about 5kWh to about 10kWh of total storage. If you need more runtime later, you can add up to five extra batteries for about 30kWh total with one TITAN main unit.

This is the battery to look at when your TITAN already handles the equipment you want to run and you need it to run longer. The main unit still determines which appliances you can connect, the output voltage and how many watts you can run at once.

Best Use Cases

• Overnight backup for essentials. Add storage for a refrigerator, freezer, Wi-Fi router and lighting when you expect an outage to last past bedtime. Measure how much energy those devices use together to size the battery bank.
• More room to store solar energy. If compatible solar panels recharge your TITAN during the day, extra storage lets you keep more of that energy for evening use. Recharge time depends on the array, weather and loads running during charging.
• Longer runtime for selected home circuits. In a TITAN setup equipped with the compatible Smart Home Panel 10, extra battery capacity can keep the circuits you’ve selected powered longer during an outage.
• Build out your backup system in stages. Start with one expansion battery, see how it handles your everyday loads, then add more storage if your runtime needs grow.

TITAN Compatibility and Connection

Designed for the TITAN 5000 Classic, TITAN 5000 and TITAN 5000 Plus. Appliances plug into the compatible TITAN main unit or use its installed home-backup setup. Use the EcoFlow TITAN connection cable specified for your stack. EcoFlow lists the standard and multi-stack connection cables separately.

Frequently Asked Questions

Does this work with every TITAN 5000 model?

Yes. It works with the EcoFlow TITAN 5000 Classic, TITAN 5000 and TITAN 5000 Plus. For a DELTA Pro or DELTA Pro Ultra system, choose the expansion battery specified for that model.

How many batteries can I add?

Each compatible TITAN main unit supports up to five extra batteries. One extra battery brings the combined capacity to about 10kWh. Five extra batteries plus the main unit bring it to about 30kWh.

Does the extra battery increase AC output?

The extra battery increases energy storage and runtime. The TITAN main unit sets the voltage, AC output rating and supported loads.

Can I charge the extra battery from solar?

Yes, through a compatible TITAN main unit. The solar array connects to the main unit, which manages charging for the connected system. The main unit’s solar input limits apply.

How much more runtime will one extra battery give me?

Divide the added watt-hours by the average load in watts for a rough estimate. One 5,017.6Wh battery represents about 10 hours at a steady 500W before inverter losses, battery reserve and system consumption. Motor loads and appliances that cycle on and off can change the result.

Do I need a Smart Home Panel 10 to add this battery?

The extra battery connects to a compatible TITAN main unit. Smart Home Panel 10 is a separate accessory for integrating selected home circuits.
