HOW DOES HOME BATTERY STORAGE WORK?
Solar Battery systems are designed to store the excess energy from your PV system. They are capable of monitoring the homes usage of electricity. The internal battery management system will automatically divert the excess energy to your battery, rather than allow it to generate back onto the grid. The battery system will then distribute the stored energy when it detects a demand in the house greater than the PV system can provide. Or when there is no PV generation, providing there is sufficient energy stored in the battery.
On average, a household would utilise 35 - 50% of the generated system without a battery. This would rise if you are in the house for much of the day. However, battery storage can raise this to 80%. If you have a system already installed and use all the energy generated from your PV system, then battery storage may not be right for you. However, if there is spare generation, then it could be a great way to further reduce your energy bill.
It is always recommended to look at your inverter monitoring to see how much of the power generated is being consumed during the day, before deciding if battery storage is right for you.
