Already have solar panels on your home or business? Adding a solar battery storage system is the next step to getting the most from your investment. For many Sydney households, solar panels alone only capture part of the savings potential. By pairing your system with battery storage, you can store excess energy during the day and use it at night, during blackouts, or in peak demand times when grid electricity costs more.

At MPV Solar, we’ve been helping Sydney families and businesses upgrade their solar since 1992. Here’s everything you need to know about upgrading your existing solar system with storage.

1. Maximise Your Solar Power Use
   Instead of exporting surplus power back to the grid at a low feed-in tariff, you can store it and use it later.
2. Reduce Power Bills Even More
   Use your own stored energy in the evenings when electricity rates are highest.
3. Energy Independence & Security
   Enjoy peace of mind knowing you can keep the lights on during blackouts or outages
4. Future-Proof Your System.  Electricity prices in Sydney keep rising. Adding storage ensures your solar keeps delivering strong long-term savings.

The good news: most existing solar panel systems can be retrofitted with battery storage. The process depends on:

• System Size – A larger solar array generates more surplus power, making it ideal for battery upgrades.
• Inverter Type – Some systems may need a hybrid inverter, or a separate battery inverter can be added.
• Energy Usage – Homes with high evening power use benefit most from storage.

Our licensed Sydney electricians and Clean Energy Council accredited installers can assess your system and recommend the best upgrade path.

• AC-Coupled Storage – Works with most existing solar systems. Easy to retrofit and doesn’t require replacing your inverter.
• DC-Coupled Storage – Installed on the DC side of the system. Usually more efficient but may require a hybrid inverter.
• All-in-One Hybrid Solutions – Ideal if you’re upgrading both panels and storage at the same time.

We install trusted battery brands such as Tesla Powerwall, Solaredge, and Sigenergy, ensuring long-lasting performance.
