HOW DOES SOLAR BATTERY STORAGE WORK?
Solar Battery Storage, for the most part, works the same as a standard grid-connected solar system BUT you have the ability to store excess energy with your batteries and draw power from them before drawing from the grid. Battery storage is another great way to further your savings or if you wish to become self-sufficient.
1. Solar Panels collect the UV/Sunlight produced throughout the day and is converted into DC Power (Direct Current).
5. Power Grid receives excess energy your system creates if it has not been stored in your batteries. Your power provider will award you with a feed-in tariff (9.13c p/kWh (Inc) in the NT), this is what creates the credit toward your power account and reduces your bill. If your energy load is larger than the solar production, you will draw only what is needed from the grid.
4. PWC Digital meter measures your power usage and excess energy sent back to the grid. It's a good way to monitor if you are drawing more power than the output of your system.
3. Battery Storage will store any excess energy your system creates for later use such as nighttime. If you have a Grid Connect with Battery Storage/ Hybrid System and your battery storage is charged any excess energy will be sent back to the grid. If you have a Stand Alone Solar Battery System then your household will run from solar production during the day and your battery storage at night, if you are using a larger load than what you solar is producing then you will draw power from your battery storage.
2. Inverter/ charger receives DC and converts it into AC power (Alternate Current). AC is the electricity you run your household on. You will draw from this electricity created by your solar panels to power your home first. Any excess power your system has created will be sent back to the grid or stored in your battery storage.
Your inverter/ charger monitors your battery level to determine when charging is needed. When your batteries reach a certain level, the solar power will be diverted to your batteries to charge them.
