FAQs
Quick answers to common questions. If yours isn't here, give us a call.
Start with how your household uses electricity, your roof and your electrical supply, then think about what you might add later, such as a battery or an EV charger. We’ll review these with you and recommend a system suited to your home rather than a standard package.
Often, yes. Whether it suits depends on your existing inverter, the condition of your system and what you want the battery to do. We’ll assess the setup before recommending an approach.
The right size depends on how much electricity you use, when you use it, your roof space and your plans, not just on how many people live in the house. We’ll look at the details before suggesting a size.
Not automatically. Most standard grid-connected solar systems shut down during an outage for safety, and backup power needs compatible equipment that has been designed and installed for it. We’ll explain what’s possible for your home.
Error messages, lower generation or an inverter that keeps shutting down are worth investigating, but they don’t always mean equipment needs replacing. We can look into the cause and explain your options, from further testing to repair or replacement.
