There is a piece of advice circulating on Victron pages that costs installers real money: that if a battery isn’t on Victron’s tested list, it can’t talk to the system, so you should fall back to a shunt and monitor it like a dumb pack. That is not what Victron says. Victron’s own battery compatibility […]

Search this question and every answer gives you a range. Five to ten years. Two thousand to five thousand cycles. Ten years or more if you look after it. What almost none of them give you is a method: a way to take the number printed on your battery’s spec sheet and convert it into

Deye publishes its approved battery list as a PDF. That is the whole user experience: a scanned document, dozens of brands in a small table, two separate files depending on your inverter, and a version number in the corner that changes several times a year. If you are holding a specific battery and trying to

The EG4 LL-S has become the reference point for 48V server rack batteries. It’s the pack most DIY builders and small installers measure everything else against, and for good reason. But “what else is out there” is a fair question, especially if you’re placing repeat orders, buying outside the US retail channel, or you’ve hit

Most “Growatt compatible battery” pages you’ll find are a straight copy of Growatt’s own PDF — a brand list, a protocol column, and nothing else. That gets you halfway. The half that decides whether the system actually commissions is the column almost nobody explains: the Lithium Mode setup code the inverter needs for that specific

If Sungrow is the classic closed battery ecosystem, GoodWe sits at the other end of the scale — and for buyers who care about battery choice, that difference is the whole story. A GoodWe hybrid inverter will happily run GoodWe’s own batteries or a range of third-party packs, across both low-voltage and high-voltage systems. That

If you’ve bought — or are quoting — a Sungrow hybrid inverter and you’re trying to work out which battery you can pair with it, there’s one fact that changes everything, and most listings bury it: Sungrow runs a closed battery ecosystem. Its inverters are engineered to talk to Sungrow’s own batteries and nothing else.

Ask three Australian installers what a “10kW solar battery” costs and you can get three answers thousands of dollars apart: $3,700 from one, $16,000 from another. Neither is lying. They’re quoting different things. One means the battery unit alone, another the whole installed system after the federal rebate, a third a premium brand with a

Before any inverter can legally connect to the grid in Australia — and before your solar or battery system qualifies for the STC rebate — the exact model has to appear on the Clean Energy Council’s approved inverter list. That list is the gate everything passes through. This guide covers where to find the official

Building your own LiFePO4 powerwall is one of the most satisfying projects in home energy — and one of the easiest to get dangerously wrong. The appeal is obvious: a 14kWh wall of storage for a fraction of a name-brand system, built exactly to your spec, fully under your control. But the gap between a

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
