In one sentence what is a solar battery?

A solar battery is like a household power bank. It stores solar power during the day and lets you use it at night or during a blackout.


Checklist to see if your home is a good fit for a solar battery | What is solar battery


Why people get one

âšĄïžŽ Blackout backup 

Keep the fridge, lights, Wi-Fi, and garage door running.

đŸ’ČLower bills 

Store cheap daytime solar and avoid buying expensive evening power.


☀Use more of your solar

Instead of selling daytime surplus for cents, save it for later use.



How it fits with your home

☀ With solar panels

  • Daytime solar powers your home first

  • Excess energy charges the battery

  • Evening: battery powers your home

  • → Maximum savings potential

⃠ Without solar panels

  • Charge during off-peak hours (cheaper rates)

  • Use stored power during peak hours (expensive rates)

  • Still provides blackout backup

  • → Lower savings but still useful

âšĄïžŽ The inverter matters

Your inverter manages battery charging and discharging:

  • Hybrid inverter — Handles solar + battery together

  • AC-coupled — Battery has its own inverter

  • Compatibility check is essential before purchase

Is your home a good fit?

Ask yourself:

  • Do you get blackouts in your area?

  • Do you have time-of-use tariffs (cheap daytime, expensive evenings)?

  • What must stay on in a blackout (fridge, lights, internet, garage door, medical devices)?



Common myths


“It always saves a fortune.” 
  • Savings depend on your usage, tariff, and battery size.


“Whole-home backup is standard.” 
  • Essential circuits are more cost-effective for most homes.


“Only one brand is reliable.” 
  • Warranty, service, and installer quality matter more than brand.
