GK'S Batteries Solar & Auto
Greg tracked down solar faults others missed — and customers keep coming back to say so.
That's a meaningful signal for solar troubleshooting in particular, where a second opinion can save hundreds. Kylie's role is distinct and worth noting — she's the product and systems expert behind the counter, and several customers single her out specifically for explaining battery and solar options in a way that helped them make a confident decision. The business is GST-registered and has been trading for around 18 years, which gives it genuine longevity for a niche local shop. When calling, it's worth asking upfront whether they service your specific solar inverter brand, since their background spans automotive and off-grid systems rather than large-scale residential installs.

About GK'S Batteries Solar & Auto
Greg and Kylie run this family-owned operation out of Harristown, where the business sits next to McDonald's on Anzac Avenue — and between the two of them, they cover a surprisingly broad range of power and energy needs. Greg is the hands-on technician: customers name him for solar diagnostics, car battery installs, breakdown callouts, and getting to the bottom of electrical faults that other shops missed or misdiagnosed. Kylie handles product knowledge and customer guidance, and multiple reviewers specifically credit her for explaining battery types, solar systems, and charging setups in plain language. What makes this shop stand out from a standard battery retailer is its crossover competency: they field enquiries about everything from car and 4WD batteries to off-grid solar for sheds and caravans, electric fence units, and residential solar panel troubleshooting — plus air conditioning servicing. They stock Century and Marshall batteries with second-hand options available for budget jobs, and they've done mobile callouts to shopping centres and remote properties when customers were stranded. Homeowners dealing with solar issues — particularly unexplained faults or underperforming systems — will find Greg's willingness to explain the problem thoroughly a genuine point of difference from bigger installers.
Best for: diagnosing tricky solar faults that other providers have missed, car and 4WD battery replacement with on-site fitting, mobile callouts for dead batteries away from home, and off-grid or caravan solar and battery setup advice.

Does GK's Batteries Solar & Auto do mobile callouts if your battery dies away from home?+
Yes — multiple reviewers confirm mobile callouts, including one customer whose battery died at a shopping centre and another who was bailed out on a Sunday afternoon. Greg came to them, supplied the battery, and fitted it on the spot. This appears to be a genuine part of their service rather than an occasional exception, though it's worth calling ahead to confirm availability and any travel distance limits from Harristown.
Can they help with residential solar panel faults, not just batteries?+
Yes, and this is one of their clearer strengths based on reviews. Greg is described as diagnosing solar issues thoroughly and explaining the fault in plain language — one customer says he fixed problems others didn't catch and then gave free advice on maintaining the system going forward. That said, their primary Google categories are car repair and store, so if you need a full new solar panel installation rather than fault-finding or repairs, confirm the scope of work with them directly before booking.
What battery brands do they stock, and do they carry second-hand options?+
Reviewers mention Century and Marshall as brands on the shelf, covering cars, 4WDs, and work vehicles. They also keep second-hand stock for budget jobs — one customer needed a cheap battery just to get a car running, and staff checked their used inventory and found a suitable option. Stock levels are described as good, with multiple customers noting they had the right battery on hand without needing to order.
Who should I ask for, and what is each person good at?+
Greg handles the technical and hands-on side — installs, diagnostics, solar fault-finding, and mobile callouts. Kylie is praised specifically for product knowledge and explaining battery types, solar charging setups, and system options in a way that makes sense to non-technical customers. Several reviewers mention both by name as a team, so you're likely to deal with both depending on whether your question is technical or product-related.
Are their prices competitive compared to larger battery or auto retailers?+
Pricing comes up positively in several reviews — one customer notes GK's was cheaper than competitors for the same battery, and another was offered a second-hand alternative to keep costs down. One reviewer specifically says GK's diagnosed their battery as needing replacement when other businesses said it was fine, which saved them money by catching the real problem. Reviews don't give specific dollar figures, so it's worth calling with your battery model or vehicle details to get a comparison quote.
