Installer Resources

If you’re buying a home battery in Australia, the question that decides whether your install passes inspection isn’t which battery you buy — it’s where you’re allowed to put it. That answer comes from AS/NZS 5139:2019, the standard that governs battery energy storage system (BESS) installation. Get the location wrong and you don’t just fail […]

 Quick answer: A 48V (51.2V nominal LFP) battery is the modern default for any solar system above roughly 3 kW — it moves the same power at a quarter of the current of a 12V bank, so it wastes less in wiring and pairs cleanly with today’s hybrid inverters and MPPT charge controllers. But “which

Quick answer: Yes — a home battery can keep your EV charging during a power outage, but only if the system is set up for it. A grid-tied battery that shuts down when the grid goes down (for safety) won’t help; you need a battery paired with a hybrid inverter that supports backup or off-grid

Quick answer: Deye publishes two official approved battery lists — one for its low-voltage (48V-class) hybrid inverters and one for its high-voltage (160–800V) models. But the list answers a narrower question than most buyers think: it names the batteries Deye has tested for closed-loop communication, not the only batteries that physically work. A 48V LFP

Quick answer: The best Tesla Powerwall alternative depends on why you’re looking past it. If you want a sealed all-in-one with a polished app, the Powerwall 3 is hard to beat. But most people shopping alternatives want one of three things the Powerwall won’t give them: a lower price per kWh, freedom to use their

Quick answer: A LiFePO4 (LFP) home battery has three different temperature windows, and only one of them decides where you can safely install it. Charging: 0°C to 45°C (32–113°F). Discharging: −20°C to 60°C (−4–140°F). Storage: about −10°C to 35°C. The mistake that costs people a battery is speccing the install location against the wide discharge

Quick answer: Yes — Australia’s federal Cheaper Home Batteries Program cuts roughly 30% off the cost of an eligible home battery. For installations from 1 May to 31 December 2026, the federal STC factor is 6.8: before retailer or admin handling, that is up to about $272 per usable kWh on the first 14 kWh,

Quick answer: Yes — a home battery works perfectly well without solar panels. It charges from the grid instead of the sun. But without solar it can only do two jobs, and they have very different economics: (1) outage backup — a charged reserve that runs your critical loads when the grid goes down, and

Quick answer: For a 48V (51.2V) LFP battery feeding a hybrid inverter on a short run (under ~5–7 ft / 1.5–2 m), size the main battery cable to the inverter’s continuous DC current plus a 25% margin, kept under ~3% voltage drop: roughly 6 AWG (16 mm²) for 3 kW, 4 AWG (25 mm²) for
