The first is physically unplugging and replugging the dongle at the inverter site. If that’s not feasible, you can use iSolar Cloud’s “Common Parameter” restart option (shown above). While Powston’s platform cannot yet initiate these commands, they have reported the issue, and Sungrow has acknowledged it. A firmware update is expected to resolve the problem, though it already appears less frequent on newer firmware versions. Regular updates are recommended to maintain the best possible performance.</p>

How to restart our Sungrow Dongle

<p>If you’re reading this, you probably have one of our older WiFi-only controllers. These required you to connect to a temporary WiFi network and enter your home WiFi details manually.</p><p>We’ve now moved on from that approach.</p><p>🔄 What’s New?<br>All current Powston controllers now come with plug-in Ethernet—just connect them to your internet router and they work automatically. No WiFi setup, no configuration steps, no hassle.</p><figure id="figure-6xrn760o1mmce1qi6x"><iframe id="6xrn760o1mmce1qi6x" src="https://www.youtube.com/embed/mpAJtw-OraY" class="w-full bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9" allow="autoplay; encrypted-media" allowFullScreen="" data-url="https://www.youtube.com/watch?v=mpAJtw-OraY&ab_channel=IanConnor" data-corners="default" data-fullWidth="false"></iframe></figure><p>❌ We No Longer Support WiFi-Only Controllers<br>If your controller doesn’t have an Ethernet port, it’s time for an upgrade.</p><p>✅ Request a Free Replacement<br>Just email service@powston.com and we’ll send you a new Ethernet-enabled controller at no charge.</p><p>We’ll make sure it’s pre-configured and ready to go—just plug it in and you're online.</p>

While an emailed token isn't as immediate as a static password, it offers significant advantages in protecting user data.</span></p><h3>Tokens and oAuth</h3><p>Our system employs OAuth or an email token-based approach. Instead of managing static passwords, we generate unique, time-sensitive tokens that are sent to the userâ€™s email. This minimizes risks like password reuse and reduces vulnerabilities related to credential storage. Similar to banking practices, this approach is designed to safeguard against the evolving landscape of cyber threats.</p><h3>We cannot confirm or deny</h3><p>A key security measure is our policy of offering generic responses during login attempts. We deliberately do not confirm if an email is registered in our system. By doing so, we prevent account enumerationâ€”where attackers might otherwise determine valid accounts by analyzing system feedback. This extra layer of protection significantly curbs the risk of phishing and other targeted attacks.</p><h3>Most advanced yet acceptable</h3><p>Though this method may introduce a small inconvenience compared to a simple password, it represents a practical balance between advanced security and user experience. The trade-off ensures robust protection while maintaining an acceptable level of usability, much like the security measures employed by financial institutions.</p>

Electric Car Charging Station With Solar Panels And Electric Chargers

<p>Proposed changes to small-scale embedded generation rules could reshape how households and businesses interact with the grid. While updates to standards and export limits aim to manage network stability, they also highlight an opportunity: to <strong>properly reward distributed battery owners</strong> for supporting the grid.</p><p>https://www.talkingenergy.com.au/changes-to-connection-standard-for-embedded-generation</p><h3>The Problem: Penalizing the Very Solutions We Need</h3><p>One concerning aspect of the changes is how battery owners could face <strong>unfair charges when importing</strong> after exporting. Imagine a home battery system exporting energy into the grid during peak demand, helping to stabilize the network and reduce strain on infrastructure. Later, when demand drops, that same household might need to re-import power at a lower rate. However, under some interpretations of the new rules, they could be hit with demand charges <strong>or additional tariffs for that import</strong>, effectively penalizing them for participating in energy trading.</p><p>This is <strong>double taxation </strong>and disincentivizes the very behaviour that grid operators should be encouraging.</p><h3>The Opportunity: A Smarter Grid With Fair Market Access</h3><p>If policymakers and network operators truly want <strong>distributed batteries to play a major role</strong> in stabilizing the grid, they must recognize the value of flexibility. Instead of penalizing battery owners, we should be:</p><p><strong>Rewarding peak-time exports</strong> that reduce stress on the network.<br><strong>Eliminating unnecessary penalties</strong> for importing after exporting.<br><strong>Encouraging demand-shifting</strong> behavior with tariffs that reflect true market dynamics.<br><strong>Creating real-time incentives</strong> that allow batteries to operate dynamically based on grid needs.</p><p>By <strong>aligning economic signals</strong> with grid reliability, we can unleash the full power of consumer-owned batteries, VPPs, and intelligent energy trading. This isn’t just about fairness—it’s about creating a more resilient, lower-cost electricity system for everyone.</p><h3>Powston’s Role in Enabling Battery Trading</h3><p>At Powston, we’ve been helping customers trade their batteries for profit and <strong>accelerate their ROI</strong>, seeing firsthand the power of market-based incentives to drive battery adoption. When the right policies are in place, batteries don’t just save money—they make money, turning consumers into active participants in the energy market.</p><h3>The Hidden Cost of Transmission Charges</h3><p>Much of the demand component in energy pricing is billed as <strong>long-distance transmission charges</strong>, even though the power may never travel long distances. From a homeowner’s perspective, this creates an unfair system where their <strong>next-door neighbour pays</strong> high transmission fees despite the power originating from the same low-voltage network.</p><p>The problem becomes even more apparent with peer-to-peer energy trading. If a homeowner sells 1 kWh to their neighbour, the network may take <strong>over 20c/kWh</strong> in peak demand fees—supposedly to cover the cost of long-distance transmission from coal power plants. However, in reality, that energy was locally generated, stored, and sold using rooftop solar and battery storage.</p><p>This outdated pricing structure discourages local energy sharing and limits the true benefits of distributed energy resources.</p><h3>The Future: Will Networks Price Themselves Out of Business?</h3><p>Ironically, networks might be setting themselves up for failure. Given that the <strong>cost of home battery storage has dropped</strong> below the cost of these demand fees, homeowners can still make a profit despite the penalties. As more consumers adopt battery storage and peer-to-peer trading models, they will bypass the traditional grid fees altogether, leading to a self-reinforcing shift away from centralized electricity models. If utilities and regulators don’t adapt, they risk making themselves irrelevant in a future where distributed energy resources dominate.</p><h3>A Time of Reckoning</h3><p>Much like other industries that have faced disruption when technology costs drop, the electricity networks may soon find themselves at a crossroads. As decentralized energy becomes more accessible, the traditional grid model faces increasing pressure to evolve. <strong>We didn’t leave the stone age because we ran out of stones</strong>—rather, we moved forward because better solutions emerged. It will be interesting to see how networks choose to respond. The future of our energy system depends on getting this balance right.</p>

Unlocking the Full Potential of Distributed Batteries for a Smarter Grid

Battery renewable energy innovation EV lithium

<p>A battery’s warranty is often defined by both time (like 10 years) and a maximum number of charge-discharge cycles. If a system costs $500 per kilowatt-hour and is rated for 4,000 cycles, that means you must earn about 12.5¢ per kWh each cycle just to break even. People sometimes interpret that as never discharging for less than 12.5¢, but that can be limiting.</p><figure id="figure-uoh37dzsehm65kyx1m"><img id="uoh37dzsehm65kyx1m" src="https://media.gettyimages.com/id/1041041644/photo/home-automation-and-smart-home-technology-lighting-control.jpg?b=1&amp;s=2048x2048&amp;w=0&amp;k=20&amp;c=HtnB84wqI0AUbaotzy50MP3sKtQVBc1Zs3vdGEJKrvA=" alt="Home Automation and smart home technology - Lighting control" title="Home Automation and smart home technology - Lighting control" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: undefined undefined;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://media.gettyimages.com/id/1041041644/photo/home-automation-and-smart-home-technology-lighting-control.jpg?b=1&amp;s=2048x2048&amp;w=0&amp;k=20&amp;c=HtnB84wqI0AUbaotzy50MP3sKtQVBc1Zs3vdGEJKrvA=" data-mce-style="aspect-ratio: 16/9; object-position: undefined undefined;"></figure><p>Here’s why. Some days, energy prices are flat and you might only earn 5¢ or 10¢ per kWh. If you skip these smaller gains, you burn precious battery time anyway—your warranty clock still ticks. Taking smaller spreads when they’re available might lower your average profit per cycle, but it prevents wasted opportunities. Over time, these “little wins” can add up, compensating for occasional lower earnings.</p><figure id="figure-6amgnfmf8pm65l9qhj"><img id="6amgnfmf8pm65l9qhj" src="https://cdn.durable.co/blocks/22W94hSjNA7S4hxulNYl0GUOMgj6AZfduQb0mOQ9rD0M7xUkcOJU2YM81Vfiu8qa.png" alt="Take smaller profits based on battery state of charge" title="Take smaller profits based on battery state of charge" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: undefined undefined;" data-corners="default" data-aspect="16:9" data-caption="example 'use it or loose it' code" data-positionX="undefined" data-positionY="undefined" data-fullWidth="false"/><figcaption class="body-normal text-gray-500 mt-2">example 'use it or loose it' code</figcaption></figure><p>That’s the essence of “use it or lose it.” If your battery still has enough capacity to recharge before the next high-price window, it makes sense to discharge for 10¢ at 2 a.m. rather than miss out. This way, you accumulate revenue steadily instead of chasing only the perfect high-rate discharge. It isn’t purely about matching the theoretical 12.5¢ cycle value; it’s about capturing the most total revenue possible over your battery’s lifespan.</p>
