Sky Energy has closed: what SkyBox owners can do now

Sky Energy, the Keysborough maker of the SkyBox off grid system, has stopped trading. What that means for owners and the practical steps to take now.

Sky Energy, the Keysborough company behind the SkyBox off grid system, has gone into administration and stopped trading. If you own a SkyBox, a company closing does not switch your system off. What has gone is the company you would have rung about it, so a few steps now will save you trouble later.

What has happened

Sky Energy's own web address now carries a notice saying the company has gone into administration and ceased trading, and that its staff, phone numbers and email addresses are no longer monitored. A separate company, Wise Energy Pty Ltd, has taken over the Sky Energy web addresses. Wise Energy says plainly that it did not buy Sky Energy's business, contracts or warranty obligations, and that it cannot honour Sky Energy's contracts or deposits. It advises owners to claim manufacturer warranties directly with the manufacturer.

So the domain has a new owner, but nobody has taken on Sky Energy's promises to its customers.

Keep the paperwork

Find everything you were given when the system went in and keep it together, on paper and as photos on your phone:

  • the contract or invoice, with the install date
  • the Certificate of Electrical Safety
  • any warranty documents or registration emails
  • the system design or single line diagram, if you were given one
  • any monitoring login details

These are what a battery or inverter maker will ask for when you make a warranty claim, and what the next electrician will want to see.

Find the brands inside the box

Off grid systems like the SkyBox are built from components made by other companies, such as the inverter, the battery and the charge controllers. Each of those has its own maker, and each maker has its own warranty. Open the enclosure doors (do not remove covers) and photograph the labels on every piece of equipment, close enough to read the brand, the model and the serial number.

Check the warranties with the makers

With the brands and serial numbers in hand, contact each component maker directly. Ask whether your unit is registered, what warranty is left on it, and how they want a claim made now that the installer has closed. If a maker asks for the unit to be registered in your name, do it now rather than when something fails.

Get your monitoring back in your own hands

If your system has monitoring, make sure you can log in to it yourself. If the account was set up under Sky Energy's name or email, contact the monitoring provider for that brand and ask how to move it to your own account. Monitoring is how a fault gets spotted early, and it is how the next person who works on the system sees what it has been doing.

Who can service it

Any licensed electrician who works on off grid systems and knows the brands inside your SkyBox can service it. When you ring around, tell them the brands and models you found, how old the system is, and what it is doing, and send the photos.

Trentham Energy looks after SkyBox systems across central Victoria. Send us the photos of the labels and tell us what the system is doing, and we will tell you plainly what we can do: get in touch, or read about our off grid upgrades and repairs.
