Battery Ready Solar

Beware of ‘Battery Ready’ solar systems that aren’t really…

A lot of customers are being misled by solar companies claiming that their systems are 'battery ready' - here's what you need to know to avoid getting burned by shonky salespeople.

If you want to get your electricity bills as low as possible, the best way is with solar panels and a battery. Some households choose to begin their solar lifestyle with a panel and battery system, while others start out with just panels and plan to add batteries at a later date.

If you’re a household leaning towards the latter, here’s what you need to know – beware of sneaky solar sales tactics, ‘battery ready’ is a term that we’ve seen applied very loosely by our competitors and is not quite accurate.  

Here’s how it works…

Solar panels generate power, inverters control it, and batteries store it. There are two ways to set up a panel and battery solar system.

1. Panels + solar inverter + battery inverter + battery (the common model)

This is the most common set up for households that start out with solar panels and add a battery at a later date. There are, however, a few downsides to this setup:

  • It’s less efficient than a hybrid inverter (we’ll get to that shortly), meaning households lose some of their solar power unnecessarily.
  • It’s more expensive to pay for two inverters than one hybrid inverter, especially when you factor in extra installation time and compatibility issues.
  • Energy monitoring can become quite confusing because the solar panel data and battery data are monitored in separate apps. To work out how much power the home is using and where it’s coming from, the household must navigate multiple apps and manually crunch some calculations.


Solar companies that use this model will often start out by selling you a solar panel system, with just a solar inverter. They market their systems as ‘battery ready’ – but, what they won’t tell is you will also need to factor in the added expense of buying and installing a battery inverter. A battery inverter fully installed will set you back around $3,000, and you’ll need to get a battery inverter + a battery down the track if you choose this route.

This is a bit like saying a backyard is ‘pool ready’ but failing to mention the fact that you will need to dig a big hole and lay some concrete!  

Why are some solar companies doing this?  Because standard solar inverters are cheaper, and it makes their offering look like a better deal than getting panels + a hybrid inverter.  What is a hybrid inverter?  I never thought you’d ask…

2. Panels + hybrid inverter + battery (the recommended approach)

A hybrid inverter blends a solar inverter and a battery inverter into one device – meaning, you can add a battery (or additional batteries) at any time, without the need for any additional hardware and cost.  It’s a bit more expensive at the start, but saves you heaps down the track as you already have the battery inverter built in.  These are additonal benefits of a hybrid setup vs. a panel inverter + battery inverter setup:

  • Power conversions are more efficient. This means there is less power lost and homeowners can use more of their stored solar power.
  • It is more cost effective to buy and install one inverter, rather than two!
  • Energy monitoring is made easy, with all data being stored in one place. Households can see exactly what’s happening in real time. 

“Battery ready” is a term that is being applied very loosely in the solar industry as of late. Any solar system can 
technically accommodate a battery, but only a hybrid inverter can take on a battery without adding additional cost.

If you’re thinking of making the switch to solar and adding a battery down the track, make sure you scrub up on the benefits of hybrid inverters. They may be slightly more expensive up front, but they will save you plenty in the long run!  Want to get a free quote for a hybrid inverter system for your home?  Click here
