What is a hybrid inverter? Types?
A hybrid inverter is a device that combines the functions of a solar inverter and a battery inverter. It can convert DC power from solar panels into AC power for home use, and also manage the charging and discharging of a battery storage system.
There are four types of hybrid inverters:
| Basic | Multimode | All-in-one | Advanced AC coupled |
| These are the most common types of inverters. They do not store energy as a backup. | This type of inverter generally has a separate space for batteries, which can be attached or detached as needed. | It includes batteries within the inverter system, allowing battery usage during power outages. | These are Deye hybrid inverters, typically used to charge batteries frequently for use during outages. However, they are less efficient compared to traditional inverters. |
What are the working principles of a hybrid inverter?
The main function of this type of inverter is to supply sufficient power during an electricity outage, serving as a backup. However, its working principle is explained below: b
- Converting DC to AC: It changes the direct current (DC) from solar panels into alternating current (AC) for household use.
- Battery management: It controls the charging of batteries with excess solar power and their discharging when needed.
- Grid interaction: It can feed excess power back to the grid or draw from it when necessary.
- Power prioritization: It decides whether to use solar, battery, or grid power based on energy production and consumption.
Which hybrid inverter is best for you?
Choosing the right hybrid inverter depends on several factors of which the main is the requirements of the power supply which can be calculated by counting the consumption of the appliances:
- Power requirements: Consider your home’s energy needs and the size of your solar system.
- Battery compatibility: Ensure it works with your chosen battery technology.
- Monitoring capabilities: Look for user-friendly monitoring systems.
- Warranty and support: Check the warranty period and available customer support.
- Cost: Compare prices, but remember that cheaper isn’t always better in the long run.
