Project Highlight
Home Power Backup System with 10kW Inventer
Overview
In this project review, we focus on a home power backup system designed to provide reliable energy storage and seamless automatic transmission between utility (Escom) and solar power sources. The system under review includes a 10kW inverter and two 8.7kWh lithium-ion batteries, ensuring continuous power supply during outages and optimal energy utilization.
System Components
- Inverter:
- Capacity: 10kW
- Function: Converts DC power from solar panels and batteries to AC power for home use.
- Batteries:
- Type: Lithium-ion
- Capacity: 2 x 8.7kWh (Total 17.4kWh)
- Function: Stores excess solar energy for use during non-sunny periods or power outages.
- Automatic Transfer Switch (ATS):
- Function: Automatically switches the power source from the inverter to Escom (utility power) in case of inverter failure, ensuring uninterrupted power supply.
System Functionality
Normal Operation
During normal operation, the system prioritizes solar energy to power the home and charge the batteries. The inverter converts the DC power generated by solar panels into AC power, which is used to run household appliances. Excess solar energy is stored in the lithium-ion batteries.
Backup Operation
In the event of a power outage or when solar energy is insufficient (e.g., during nighttime or cloudy days), the system seamlessly switches to battery power. The stored energy in the lithium-ion batteries provides backup power to the home, maintaining continuity in power supply.
Automatic Transfer Switch (ATS)
If the inverter fails, the ATS comes into play. The ATS automatically transfers the load from the inverter to the Escom grid. This automatic transfer ensures that there is no disruption in the power supply, providing peace of mind to the homeowners.
