A battery module is the battery alone, without an inverter. It adds capacity to a system or builds one with an inverter it is made to work with. Its efficiency and standby draw depend on that inverter, so we list modules without a rank.

Check which inverters the maker names before you buy, then compare the usable capacity, the voltage and the warranty. The price is today’s lowest including shipping.

Grows to 10 kWh or more, 0 models
Grows to 20 kWh or more, 0 models

The largest capacity the maker says the system reaches with extra modules, otherwise its own capacity.

Coupling

Coupling

Does not matter, 0 models
AC, charges from a socket, 0 models
DC, solar panels plug in, 0 models

AC coupled charges from a socket or an existing solar inverter. DC coupled takes solar panels straight into the battery. A model that does both passes either.

Backup

Backup

Does not matter, 0 models
Yes, the whole home, 0 models
Yes, the essentials, 0 models
No, backup is not why I want one, 0 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.

Solar panels

Solar panels

Does not matter, 0 models
Yes, on the roof, 0 models
Yes, a balcony set, 0 models
No panels, 0 models
Not yet, they are coming, 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.

Installation

Installation

Does not matter, 0 models
I plug it in myself, 0 models
An installer, 0 models
Not decided yet, 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.

Location

Location

Does not matter, 0 models
Indoors, 0 models
In a shed or garage, 0 models
Outdoors, 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.

Power use

Power use

Does not matter, 0 models
Under 600 kWh, 0 models
600 to 1,000 kWh, 0 models
More than 1,000 kWh, 0 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.

Backup power

Backup power

Does not matter, 0 models
Any backup power, 0 models
Backs up house circuits, 0 models

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

Ecosystems

Based on the voice assistants and Matter support the maker lists. A model that lists none of them is left out.
