Battery Storage Systems, Hybrid Systems, Home or Solar Batteries, and Energy Storage Systems (ESS) are all terms used to describe a range of battery products you can buy for your home.
Grid connected battery storage products do vary, but they all have one thing in common. Unlike off-grid systems, these batteries are suitable for grid connected homes. They are designed to give you a level of energy independence and control that solar alone cannot provide.
There are solar self-consumption products like the Tesla Powerwall, designed to drag excess solar in to the night instead of selling back to the grid; the Alpha ESS which will run selected circuits during blackouts; to higher capacity products like the Autonomy System which can run your entire home, or take you off-grid entirely.
For on grid storage, different brands of battery units will have different functionality. However generally speaking, a grid connected battery system works like this:
Photovoltaic (PV) solar panels convert sunlight to direct current (DC) electricity, which is then fed through the solar inverter to create usable alternating current (AC) electricity. AC electricity is then sent to the switchboard, where it is sent to the household appliances that are using electricity at the time, and any surplus electricity is sent to the battery bank to recharge it.
The inverter/charger will stop the solar system from recharging the batteries once they are full, and divert excess solar power not required by your appliances to the mains grid via your meter.
When your solar system is not producing electricity, your battery bank will send power to your household appliances. If the battery bank state-of-charge level gets too low, the inverter/charger will allow electricity from the mains grid to power the house electrical appliances and recharge the battery bank.
How much battery storage capacity to buy is probably your main consideration, but this depends on a few things:
