FAQ
Q: What configurations are available?
A: The ATG Home Battery Stack uses modular 5 kWh batteries and up to four can be stacked together. The system has two options for the hybrid battery inverter of 10 kW or 12 kW. You can pair the 10 kW with either two stacks (10 kWh), three stacks (15 kWh), or four stacks (20 kWh). With the 12 kW hybrid inverter option, you can pick either three stacks (15 kWh) or four stacks (20 kWh).
Q: What is a hybrid inverter?
A: The inverter is the component of the system that converts the DC voltages of the battery to the AC voltages used in your home plugs. Our inverter is a hybrid because it supports both batteries as well as solar panels. This means with our system you do not need a separate solar inverter.
Q: What if I happen to have an existing solar installation.
A: On our hybrid inverter, there is an option to add another AC power source such as an existing solar installation. This allows the Home Battery Stack to also manage the existing solar installation’s power generation.
Q: Can I add a generator to my system?
A: You can add a generator using the additional AC power source input. This allows you to control the generator using the Home Battery Stack control app on your phone or tablet.
Q: Can I backup my whole home?
A: By adding the additional Whole Home Controller, you can enable whole home backup. Otherwise, you can use the Home Battery Stack to backup your most important electrical systems on a dedicated backup subpanel.
Q: Where can I install the Home Battery Stack?
A: The system can be installed in non-occupied residential spaces such as in garages and basements. It can also be installed outdoors on the side of the house or garage.
