About Solar Battery Inverter
What is a Battery Inverter?
Let consider a scenario in which you have a grid-tied solar system, and due to some reason, the utility supply interrupted, at that time what are you gonna do? Or let's say, you want to run your energy system complete by green energy during night time too. How it’s possible? The answer is battery inverter or in some case also known as Hybrid inverter. Thus, a battery inverter or hybrid inverter is primarily used for grid-tie purposes but also has the added feature that they provide backup power to your home when the electric utility fails.
The battery inverters enable the integration of storage systems into the utility grid or self-sufficient off-grid systems. They assume important grid management functions and ensure a reliable energy supply as well as the optimal integration of renewables into the power supply.
When & Where Does it Needed?
- Used as an integrated battery backup system when a grid-tied system fails.
- Can be used during the night to lower the dependency on utility connection

Hybrid Inverter Advantages
- It allows you to store excess solar or low cost (off-peak) electricity.
- Allows use of stored solar energy during peak evening times (known as self-use or load-shifting)
- Most battery inverters have backup power capability.
- Reduces power consumption from the grid (reduced demand)
- Enables advanced energy management (ie. peak shaving)
Hybrid Inverter Disadvantages
- Higher cost. Mainly due to the high cost of batteries.
- Longer payback time - A higher return on investment
- More complex installation requires more room and a higher install cost.
- The battery life of 7-15 years.
- Backup power may limit how many appliances you can run at the same time (depending on the type of hybrid inverter and its capability)
