• Yes, a balcony set0, 0 models
• No panels0, 0 models
• Not yet, they are coming0, 0 models

A battery keeps what your panels make in the day for the evening. A balcony set needs a battery made for it, and without panels a battery charges from the grid, so we keep only models that can.

• Not decided yet0, 0 models

A plug-in battery goes into a wall socket, and some need an electrician only for more power. A larger system is connected to the fuse box by an installer.

• One phase0, 0 models
• Three phases0, 0 models
• I do not know0, 0 models

Most homes have one phase and some have three, which the fuse box shows. We do not narrow the list by it: ask your grid operator whether a battery on one phase offsets what the other two use.

• Does not matter0, 0 models
• Indoors0, 0 models
• In a shed or garage0, 0 models
• Outdoors0, 0 models

Indoors every battery will do. In an unheated shed or garage it has to charge below freezing or warm itself, and outdoors it needs a model made for it, rated IP65 or better.

• 2,500 to 4,000 kWh0, 0 models
• 4,000 to 6,000 kWh0, 0 models
• More than 6,000 kWh0, 0 models

A rough guide to the size: up to 2,500 kWh a year any battery helps, up to 4,000 about 3.75 kWh of storage, up to 6,000 about 6 and above that about 9. We leave out only systems that cannot grow to that size.
