Every home that installs a battery storage system will need an inverter to convert the stored DC electricity into grid & appliance-friendly AC electricity.
What is an energy storage inverter?
An energy storage inverter represents the latest generation of inverters available on the market. Its primary function is to convert alternating current (AC) into direct current (DC) and store it in batteries. During a power outage, the inverter converts the DC stored in the batteries back into AC for user consumption.
Every home that installs a battery storage system will need an inverter to convert the stored DC electricity into grid & appliance-friendly AC electricity. The two main choices available are battery-specific inverters and so-called 'hybrid' or multi-mode inverters.
Why do I need an inverter/charger?
Many power loads also require standard AC current. For both these reasons, an inverter/charger is required to keep batteries adequately charged and provide power that can be widely used. On the other hand, inverter/chargers are not equipped to directly charge batteries from the DC current provided by a PV array.
In storage/backup systems without PV, you only need an inverter/charger to connect the system. Still have questions about inverter/chargers or charge controllers?.
Do inverter/Chargers need a charge controller?
On the other hand, inverter/chargers are not equipped to directly charge batteries from the DC current provided by a PV array. A charge controller is needed to appropriately match the PV voltage to the battery and regulate charging. In some PV + storage applications you may only need a charge controller.
Can a battery inverter be installed in a home?
Battery inverters can be installed into homes where no solar PV system exists for purposes of energy arbitration (i.e. using cheap off-peak grid electricity for battery charging), but most homes are more likely to install them in order to capture and store excess solar energy.
