• Does not matter3, 3 models
• Yes, the whole home0, 0 models
• Yes, the essentials1, 1 model
• No, backup is not why I want one3, 3 models

A battery keeps the whole home running only with a route that switches the whole panel over, and the essentials (the fridge, lights, a furnace fan) with one that switches chosen circuits. We go by the backup each maker states, and a model that states none is left out of both.

• Does not matter3, 3 models
• Yes, on the roof3, 3 models
• Yes, a balcony set0, 0 models
• No panels0, 0 models
• Not yet, they are coming3, 3 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.

• Does not matter3, 3 models
• I plug it in myself2, 2 models
• An installer3, 3 models
• Not decided yet3, 3 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.

• Does not matter3, 3 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.

• Under 600 kWh3, 3 models
• 600 to 1,000 kWh2, 2 models
• More than 1,000 kWh2, 2 models

Your bill gives it in kWh. A rough guide to the size is half a day’s use: under 600 kWh a month any battery helps, 600 to 1,000 about 10 kWh of storage, above that about 17. It is one maker’s rule of thumb, so we leave out only systems that cannot grow to that size.

What keeps working in a power cut, as the maker states it: one socket on the battery, or circuits in the house.
