What is a single-phase solar battery?
 

A single-phase solar battery is one that is charged via a single-phase power supply. Most households have a meter configured in this way. All electrical appliances are therefore connected to a single phase, which supplies them with electricity. 

In a photovoltaic installation, the solar panel receives the light, which is converted into direct current. An inverter or micro-inverter converts it into alternating current, which passes through this single-phase electrical circuit. A single-phase solar battery is therefore suitable for this type of installation.
 

Which single-phase battery should you choose? 
 

How do you choose your solar battery? You need to consider how you want to use it, as well as your electricity consumption. Ask yourself what appliances you want to power and how much of your electricity consumption you want to devote to your battery. 

Here are the criteria to consider when choosing your single-phase battery: 

• Storage capacity: this is expressed in kWh or Ah. It corresponds to the quality of energy that the battery can store. You need to know your electricity consumption to know which capacity to choose.
• Life cycle: a battery can withstand a number of charge and discharge cycles over its lifetime. The higher the number of cycles, the longer the device will last.
• Energy efficiency: this is the proportion of stored energy that is returned when the equipment is used. It is expressed as a percentage.

 

Available technologies: which one is right for you? 
 

There are different single-phase battery technologies: 

• Open lead batteries: these are the least expensive, but also the most difficult to maintain. It has a limited lifespan. 
• Gel batteries: these also contain lead combined with a liquid electrolyte. It is more stable, but charges very slowly. 
• AGM batteries: these are halfway between open lead-acid and gel batteries. Complete discharge of this battery may damage it.
• The lithium-iron-phosphate solar battery: this is the type of battery we recommend. It has a long service life, because it can withstand a large number of cycles. It's particularly reliable, has a high output and can withstand extreme temperatures.

Compatibility and installation: what you need to check 
 

To check whether your installation is single-phase, look at your electrical panel: 

• For single-phase, you'll see 2 main wires coming from the meter; 
• For three-phase, you'll see 4 wires coming from the meter. 

You can also look at your electricity meter: 

• On older meters, it says MONO ; 
• On electronic meters, if the installation is single-phase, you will see the words ‘230 V’ in the bottom left-hand corner.
• On a Linky meter, you need to look at the logo engraved on the frame of the digital screen. A logo with a single branch ending in a single circle indicates a single-phase installation. If this logo has three branches, then your installation is three-phase.
