benefits of batteries
In a nutshell, battery storage works by storing excess solar energy from the PV system for use at night. With current low export tariff rates, this not only creates additional savings but also becomes a valuable long-term investment. Another key benefit of storage systems is that they protect your home from power outages and help reduce reliance on grid supply.
Use your own stored energy
Benefits
- Solar panels capture sunlight and convert it into DC electricity.
- An inverter changes this DC electricity into AC, which powers household appliances during the day.
- Excess electricity produced by the panels is used to charge the batteries.
- Once the batteries are fully charged, any extra solar energy is sent to the grid as usual.
- The stored battery energy is used during night-time hours, reducing reliance on the grid for electricity.
By using your own stored energy, you do not need to buy more expensive electricity from the grid.
Since the batteries are 'always on,' you will never experience a power outage.

AC Coupled Storage
Currently, one of the most economically efficient systems on the market involves placing batteries between the solar panels and inverters, allowing them to directly store DC power generated by the panels. It’s important to note that these batteries are not designed to store electricity from the grid. This type of battery setup is ideal for storing surplus solar energy for nighttime use but does not provide protection against grid failures. In the event of a grid outage, the system will cease to function.
DC Coupled Storage
Typically, this category of storage solutions can store energy generated by solar panels and also supplement it with grid electricity. They have the capability to offer an uninterrupted power supply even when disconnected from the grid. While they tend to be relatively more costly, they provide the flexibility to draw energy from various sources. For instance, homeowners can tap into grid power during periods of lower electricity tariffs.
