Here's a clear explanation of how the battery pack, solar panels, and inverter in a residential solar system work together:

A residential solar power system is made up of several key components that work as a team to provide clean electricity for a home.

Solar Panels (PV Modules)

Solar panels capture sunlight and convert it into direct current (DC) electricity using the photovoltaic effect.They are the starting point of the system, producing energy whenever the sun is shining.

Inverter

Homes use alternating current (AC) electricity, but solar panels produce DC.The inverter’s job is to convert DC into AC, making the electricity usable for household appliances.It also helps regulate system performance and may include smart monitoring functions.

Battery Pack (Energy Storage)

When solar panels generate more power than the home needs, the extra electricity charges the battery pack.The battery stores energy for later use, such as at night or during cloudy weather.A Battery Management System (BMS) ensures safe charging, protects against overcharging, and balances individual cells.

Home & Grid Connection

Electricity flows from the inverter into the home’s electrical panel, powering appliances and devices.If there’s extra energy (and the battery is full), it can be sent back to the utility grid.If solar power and the battery aren’t enough, the home can draw electricity from the grid.

In simple terms:

Solar panels capture sunlight → Inverter makes the power usable → Battery stores extra energy → Home uses it anytime, with the grid as backup.
