How Solar Batteries Allow Solar Panels to Work During a Power Outage
In Australia, power outages are increasingly frequent because of storms, heatwaves, grid maintenance, and the growing energy demand. Homeowners often expect that solar panels will provide them with uninterrupted power, but they are surprised to find that the lights go out during a blackout. This brings us to one of the most frequent questions we get at Electrical Masters: will solar panels work during a power outage?
The quick answer is: not if you have a solar battery. This blog will cover how solar batteries function, the reason typical solar systems go offline during blackouts, and how the correct battery setup can maintain power in your home when the grid goes down.

Why Standard Solar Panels Don’t Work During a Power Outage
In Australia, most homeowners have solar systems connected to the grid. They are built to return extra electricity to the grid and generate energy when solar production is low.
But to ensure safety, grid-connected solar systems automatically turn off during a power outage. This stops electricity from flowing back into the grid while workers are on the lines.
This means that despite bright sunshine, the answer to whether will solar panels work during a power outage is no, unless your system has battery backup or blackout protection.
What Is a Solar Battery and How Does It Work?
A solar battery stores excess energy generated by your solar panels during the day. Instead of sending all unused power back to the grid, the battery saves it for later use.
When the grid goes down, a solar battery:
- Disconnects your home from the grid
- Supplies stored electricity to essential appliances
- Allows your solar panels to continue producing power safely
This is the key reason will solar panels work during a power outage changes from “no” to “yes” when a battery is installed.
How Solar Batteries Enable Power During Blackouts
A hybrid or battery-ready inverter is used together with solar batteries. While in operation, your system works just like any other solar setup connected to the grid. However, when an outage happens, the battery system puts your home into backup mode.
Here’s what happens step by step:
- Grid power fails
- Battery system isolates your home from the grid
- Stored solar energy powers your home
- Solar panels continue charging the battery during daylight
This seamless transition is why many homeowners install batteries specifically to answer will solar panels work during a power outage with confidence.
What Can You Power During a Blackout?
With a solar battery, you can choose to power:
- Lights and power points
- Refrigerators and freezers
- Wi-Fi and home offices
- Medical equipment
- Security systems
Electrical Masters creates personalized backup circuits to ensure your essential appliances keep running during power outages.
Battery size is what dictates how long power lasts, but even a small battery can significantly impact the answer to whether will solar panels work during a power outage.
Do Solar Panels Work at Night During an Outage?
Solar panels don’t produce electricity at night, but batteries store daytime energy for later use.
This means during a nighttime blackout:
- Your battery supplies stored power
- Essential appliances continue running
- Solar panels recharge the battery the next day
Without a battery, will solar panels work during a power outage at night is always a no.
Grid-Connected vs Battery-Backed Solar Systems
Let’s simplify it:
Standard Grid Solar
- Cheaper upfront
- Shuts down during outages
- No backup power
Solar with Battery
- Higher upfront cost
- Power during blackouts
- Energy independence
- Protection from rising electricity prices
For homeowners who value reliability, battery-backed solar is the clear winner when answering will solar panels work during a power outage.
Are Solar Batteries Worth the Investment?
While solar batteries require an initial investment, they offer long-term value through:
- Power security during blackouts
- Reduced reliance on the grid
- Better use of your solar energy
- Protection against rising energy costs
Batteries also make properties in Australia more valuable and attractive to potential buyers. Families that work from home or depend on medical devices will find that the peace of mind alone makes the investment worth it.
If you’ve ever been scared that will solar panels work during a power outage, a solar battery is the answer.
