title: I have an Eco ESS Gateway installed. Does this provide whole-house backup in the event of a power cut?
description: "With an ECO ESS Gateway. If your installer has wired it correctly and activated backup in the Dura I app, your whole house can stay powered during a power cut, but only up to your inverter’s maximum output (3.6kVA: 13.1A, 4.6kVA: 18A, 5kVA: 21.7A, 6kVA: 26.1A), as exceeding it will trip the inverter and require a reset."

# I have an Eco ESS Gateway installed. Does this provide whole-house backup in the event of a power cut?

If wired in correctly by an installer, and been activated on the Dura I app, you will have cover on your whole house during a power cut, providing you do not go over the max limits specified below.

Inverter Backup output capabilities are as follows:

- 3.6KVA – 13.1A
- 4.6KVA – 18A
- 5KVA – 21.7A
- 6KVA – 26.1A

Backup must be switched on in settings for critical loads to receive constant power supply.

Unfortunately, like all back-up systems, there is a limit to how much power can be interpreted in an AC off Grid scenario. So, although you have put the whole house electrics on the inverter through the back up port, you will only be allowed to use the max number of amps equal to its size. If you were to use too much power, the inverter would trip and require resetting.
