Save more than just power with battery storage
The idea of battery storage is to save up the additional solar power that you accumulated during the day to be used at night when the system is not producing power.
This is a more efficient way of running the system than selling the excess power back during the day at lower rates.
If you operate on a time of use tariff, you will be able to buy grid power during cheaper periods, minimising how much you buy during peak periods. The battery systems can be set up to give you power during an outage. There are a number of options for configuration, namely the Hybrid inverter, AC Coupled and DC Coupled solutions. We will provide a brief description below but out experienced consultants can advise you on the most suitable options for your needs.
Types of Energy Storage Systems
DC Coupled Storage
Fitted between the inverter and the solar panels, this configuration will know when the system is producing excess power and send it to the batteries. At times when you are using more power than you’re producing, the stored power is then sent back to the inverter. The main advantage of this setup is that the power is stored prior to being converted to AC. This saves on unnecessary conversions. The drawback is that you can not draw power from the grid to store for later use.
It has the ability to be setup to supply power during an outage.
It is an efficient, effective system and can generally be adapted to any existing system.
AC Coupled Storage
This is the most common type of system. It is not as cost effective or efficient as the DC coupled, it does still have major advantages.
The main one being that AC coupled storage can draw power from the grid, allowing you to buy it at the lower rates and prevent you from using the grid at peak times.
They can also be set up for battery backup and can store excess solar energy. AC coupled systems work separately from the solar power so they will easily connect to any system and still allow you to get from other sources.
As the name suggest, these offer the best of both worlds as described above. They are specifically designed to work with solar and batteries and give you a great advantage.
Hybrid inverters will give you both DC and AC coupled solutions, so you get the benefits of both systems. You can store power in the batter without converting it to AC, avoiding the unnecessary future conversions. Because it is also AC coupled, you can still use features such as battery backup and power storing during lower rate times. It is all done seamlessly and automatically from one unit so will work out the most efficient way to operate.
These systems are becoming extremely popular with people wanting the advantages of both systems.
All the monitoring is also done from one unit, so you don’t have to worry about separate monitoring packages for both your storage and solar systems. We are now seeing more and more of these units as they a great fit for residents looking to incorporate solar and storage.
