Founder Derek McKercher accepted the award at the Hilton Shanghai Hongqiao on behalf of the Western Australian team, in a room that held Sigenergy’s
Every lithium battery slows down in the cold, and below 0°C internal cell temperature, charging stops being safe at all. Tesla’s answer in Powerwall 3 is Heat Mode: dedicated resistive heaters bonded to individual battery cells, run by software that predicts when warmth will be needed. Tesla published a white
Western Australia is the growth story of the NETCC Annual Report 2025. The number of NETCC Approved Sellers based in WA rose by more than 420% year on year, the largest increase of any state, and the report credits one thing for it: the WA Residential Battery Program. I have
On 6 May 2026, at Doltone House in Sydney, Nicole Bilman was named runner-up for Emerging Leader of the Year at the Smart Energy Council Excellence Awards. The category recognises individuals shaping the next generation of Australia’s renewable energy industry, judged by an independent panel from a national field of
Every solar and battery system installed in Western Australia is, in the eyes of the law, an electrical installation. Not a product. Not an appliance you plug in. The work of connecting panels, inverters and batteries to your switchboard can only be performed by licensed electricians, and the business that
In May, in a conference hall in Sydney, an analyst’s spreadsheet became four physical awards. Each one had Perth Solar Warehouse printed on it. Nobody from the group wrote a submission, polished an entry, or pitched a judging panel. SunWiz just counted. TLDR Perth Solar Warehouse, our residential and localised
Two-phase properties can run Sigenergy hardware. That is the short finding from two technical documents Sigenergy issued in mid-2025: a Declaration of Two-Phase Operation Compatibility from the Sigenergy service team (May 2025) and a two-phase design scenarios overview (V2, dated 7 June 2025). I have been through both, and the

When PSW Energy commits to carrying a manufacturer’s product, the commitment starts well before a spec sheet lands on someone’s desk. It starts at the factory. In March this year, our team travelled to China to visit four of our key manufacturing partners. The GoodWe leg of that trip covered

The Alpha ESS visit in Nantong was the leg of our China trip that we approached with the most history. Alpha ESS is not a new name to anyone who has been in the Australian solar industry for any length of time. The brand has been a steady presence in
The GoodWe Three-Phase ESA All-in-One energy storage system has officially received Clean Energy Council (CEC) approval, clearing the way for Australian homes and businesses to access one of the most versatile battery storage solutions on the market. Stock is expected to arrive from late March to early April 2025, and
This update is specifically for existing iStore and Huawei customers who already have an iStore 5kWh battery system installed (IS-BATT-5000-ES), and are considering adding more storage capacity. iStore is transitioning from the current 5kWh battery (IS-BATT-5000-ES) to a new 7kWh battery model expected to launch around June (pricing to be

Australia’s household battery market has shifted from early adoption to rapid scale-up, driven by policy incentives and grid-operational pressures.

Every solar company in Perth can call itself “the best”. Some point to awards. Some point to installation volume. Some just say it louder than the next guy. But solar isn’t a purchase you judge on install day. It’s a 10–20 year relationship with your roof, your power bills, and
Residential solar-and-storage is evolving, focusing less on hardware functionality and more on optimisation: maximising watts per square meter on rooftops, ensuring sufficient kilowatts for motor starts, achieving reliable islanding in grid outages, and integrating batteries, inverters, and loads into a cohesive system. The key technologies, PV physics, lithium-ion design, and
