Sometimes the right solar and battery advice is: “I need more information before I recommend anything.”

I recently reviewed a homeowner’s electricity bill and existing 6.6 kW solar system.

The initial figures looked encouraging:

☀️ Average solar exported: 12.1 kWh per day
⚡ Average electricity purchased: 10.88 kWh per day
💰 Export rate: only 3¢ per kWh
📈 Purchase rate: approximately 32.9¢ per kWh

At first glance, a battery may make good sense. The home is selling surplus solar cheaply during the day and buying electricity back later at more than ten times the price.

But just the electricity bill doesn’t tell the whole story.

Before recommending a battery or deciding what size it should be I’ve asked for 12 months of interval data, solar-production history, inverter details, switchboard photos and information about the home’s major electrical loads.

Just as importantly, I need to understand exactly what the client wants the system to achieve. That may include:

• Lower electricity bills and the best financial return
• Greater energy independence
• Blackout backup for essential circuits or the entire home
• Additional solar generation
• Preparing for future EV charging
• Accommodating increased use from air conditioning, a pool or other major appliances
• A combination of these objectives

The right system can look very different depending on the client’s priorities. Battery design isn’t simply about how much equipment will fit it’s about what outcome the customer actually wants.

I also want to investigate whether the electric hot-water system can be shifted into the middle of the day. Using surplus solar directly may provide a worthwhile saving before asking the customer to spend money storing that energy in a battery.

Only after reviewing the complete picture can we properly determine:

• Whether a battery provides good value
• What battery size actually suits the home
• Whether the existing inverter can be retained
• Whether additional solar panels are worthwhile
• Which loads can be moved into solar-production hours
• What level of blackout backup is practical

At Reefcosa Electrical Air & Solar, our aim isn’t simply to sell the biggest solar and battery system we can.

It’s to understand how your home uses electricity and recommend the system, or sometimes the simple adjustment that delivers the best result for you.

Good solar and battery advice begins with evidence, not assumptions.

Big personal milestone for me today.

This whole journey started because last year I wanted to install a battery at my own home and honestly, I found it way harder than it should have been to get clear advice and real support.

So instead of settling, I decided to do something about it.
That meant:
• Finding a battery course (which wasn’t easy)
• Travelling interstate to complete the training
• Sitting more exams, jumping through accreditation hoops, and paying the fees that come with doing it properly

While all that was going on, I installed a system at my own place and another for a customer, learning firsthand what works, what doesn’t, and what really matters.

I’m proud to say I’m now fully accredited to install solar and battery systems now.

If you’re looking to reduce power bills, protect yourself against outages, or just want straight advice from someone who’s been through it personally, I’m ready to help.

No pressure. No hype. Just honest guidance and compliant installs.

🔌 STORM & POWER SAFETY: WHAT YOU NEED TO KNOW ⚡🌪️
With severe weather events on the rise, it’s crucial to prepare for power outages and stay electrically safe before, during, and after storms, cyclones, and floods. Here are some key safety tips to protect your home, family, and property:

✅ Before the storm:

🔋 Charge your mobile phone in case of emergency.
🔌 Know how to turn off your mains power.
⚡ Shut down your solar system following manufacturer instructions.
🔦 Test your generator & ensure a licensed electrician such as us has installed a changeover switch if you plan to connect it to your home's wiring.
🩺 Have a backup plan if anyone in your home relies on powered medical equipment.

⛈️ During the storm:

🔌 If power goes out or is fluctuating, unplug sensitive electrical devices to prevent damage.
⚠️ Avoid using generators, extension leads, or electrical appliances in wet areas!
⚠️ Beware, in some conditions such as when fallen powerlines occur, metal items such as your meterbox could be alive. 🚨 Report damaged power lines immediately to your electricity provider and listen to instructions

🌊 After the storm or flood:

⚠️ Assume all fallen power lines are live—stay well away!
🏡 Check your property for damage. A licensed electrical contractor must inspect your home before power is restored.
🔋 Flooded electrical equipment? Have it tested before turning it on.
🔌 If entering a ceiling space, turn off power at the switchboard first.
🔧 Solar & battery storage: Get a professional to inspect it before use.

⚡ Generator Safety:

🚫 Never run a generator indoors—carbon monoxide poisoning is deadly.
🔌 Use generators only for essential equipment, like fridges.
🛑 "Su***de leads" are illegal & extremely dangerous—don’t use them! (male at both ends)

🚑 Electric shocks? Take them seriously.

⚠️ If you experience tingles or shocks from appliances or taps, call your electricity provider immediately.
❌ To avoid multiple casualties, never touch someone receiving a shock unless trained—turn off power at the source and call 000.

👉 📢 Play it safe, always use a licensed electrician for electrical repairs & if you need advice, contact us today! 📲☎️📞

Finally decided to test the Starlink out myself

Need a roadworthy or an inspection on a vehicle you’re considering from someone who really knows their stuff? You may think I am bias, but Justin Kenway has bought and sold more cars than I have had birthdays and worked on 10 x that, so what he doesn’t know about buying a vehicle or bike isn’t worth knowing. He’s just taken a leap of faith and established his own business, so he’ll really appreciate your support.

Just a shout out to any fellow caravaners.

I recently replaced my damaged towbar and fitted an adjustable hitch whilst at it so I could fine tune the ride height to get the van level.

When I initially set it up it was a little too high. I didn’t bother to change it straight away, but noticed there was a very slight tail wobble at times.

I adjusted it this morning and have just done about 400 klms. What a great difference it has made!!!!

Just thought I would share this in case anyone was on the fence about the benefits. Of course weight distribution plays a role in it too.✌🏽
