🛠️ Plan Your Install

Before we can confirm your quote or schedule an installation, we need to understand a bit about how and where you'd like the battery installed.

  • ✅ Whether you're installing the battery inside (garage) or outside (side of house)
  • ✅ Whether your system is being installed as an AC-Coupled setup (added to an existing solar system), or a DC-Coupled setup (as part of a new installation or replacing an exising inverter)

These options affect:

  • How the system is wired
  • Where components can be safely mounted
  • What rebates may apply
  • The type of photos we’ll need from you

FAQs

❓ Frequently Asked Questions

Q: Will the SolaX Home Battery System work during a blackout?

A: Yes — many SolaX home battery systems include built-in backup and emergency power capability. This allows the system to provide power to critical loads such as lights, refrigerators, and other essential appliances during a blackout. Depending on the model, you can get several kilowatts of surge capacity to help keep your home running when the grid goes down.

Q: How much can I save using the SolaX Home Battery System?

A: You can save hundreds of dollars per year by storing excess solar energy generated by your solar panels and using it during high-tariff periods instead of drawing from the grid. Your actual savings will vary based on your household energy usage, solar production, and local electricity rates.

Q: Can the SolaX home battery be installed on an existing solar system?

A: Yes — SolaX batteries and hybrid inverters are designed to be retrofitted to most existing solar systems (subject to compatibility). Our installation team will assess your current setup during the quoting and site inspection process to confirm whether a SolaX battery solution is suitable for your system.
