Growatt Whole Home Backup Power System

A hybrid inverter, a high-voltage battery and an automatic transfer switch, supplied as one matched system for a house with heavy loads. It stores solar or off-peak grid energy, carries the house through an outage, and returns to normal automatically. The kit is built around the Growatt MIN 11400TL-XH-US 11.4kW hybrid inverter and the ATS-XH-US transfer switch; choose 10kWh or 20kWh of battery.

What's included:

• Growatt MIN 11400TL-XH-US 11.4kW hybrid inverter
• APX high-voltage LFP battery — 10kWh or 20kWh, depending on the option you choose
• Growatt ATS-XH-US 11.4kW backup box, with a built-in split-phase transformer for 120V / 240V output
• Growatt smart meter

Solar panels are not included. This is a storage and backup system, not a solar kit. It works with an array you already have, or panels can be bought separately and sized to the inverter — ask us and we will work out how many you need.

Suited to households with high daily consumption, and to homes with heavy loads such as electric vehicles and swimming pools. It maximises self-consumption of solar energy, reduces electricity bills, and keeps the house running through an outage.

System key features:

• Energy independence: generate and store your own energy to reduce reliance on the grid.
• Self-consumption optimisation: store energy when it is cheap or plentiful and use it at peak.
• Outage cover: switches to off-grid mode automatically when the grid fails.
• Flexible energy management: self-consumption, zero export, time-of-use and off-grid modes.
• High efficiency: up to 98.5% with 4 MPP trackers.
• Monitoring: built-in 4G/WiFi, with real-time data through the app or web portal.
