🎾 YES, ALEX! What a comeback! 🙌

Match point against. Down 2‑6, 3‑5. One point from defeat. And Alex de Minaur? He didn’t blink.

At Laver Cup London, he saved match point at 9‑8 in the deciding tie‑break and pulled off a stunning 2‑6, 7‑6(5), 11‑9 win over US Open champion Alexander Zverev. He lost four service games and won just 59% of his first‑serve points. The numbers didn’t favor him. But he left everything on the court. 💪

That’s why Alex is our first global brand ambassador. Not for one flashy moment - but for the daily grind: relentless endurance, constant movement, steady ex*****on, and the guts to never let go when it matters most.

It’s the same spirit behind “Relentless Energy.” No gimmicks. Just solid tech and reliable products that stay online when you need them.

As our Chairman & CEO Samil Ouyang puts it: “True victory - whether in a deciding set or managing energy for homes and industry - is built point by point through relentless power.”

When you choose SAJ electric energy storage, you choose a partner built on proven tech, rigorously tested, and reliable at the critical moment.

Every comeback on court is a metaphor for the reliability of SAJ electric products. 🔋

Not luck. Not a miracle. Just relentless energy.

We're thrilled to announce SAJ at Romania's Green Momentum Summit! 🎉

Our Romania Country Manager, Adrian Teodor Susca, took the stage as a guest speaker, sharing insights and joining a roundtable discussion on Romania's clean energy transition. 🎤

On stage, Adrian shared SAJ's proven renewable energy and storage solutions, covering market opportunities, policy trends, and practical ways to speed up Romania's green energy rollout.

It was a great chance to exchange ideas with policymakers, installers, and industry stakeholders, and to explore new partnerships for local decarbonisation. 🤝

SAJ remains committed to supporting Romania's energy shift with reliable, future-ready solar & energy storage technology. 🔋

Energy management shouldn't need a manual. ⚡

With AI Keeper's "Circle to Ask", understanding your energy system is as easy as drawing a circle.

See something you don't get in the elekeeper app?
⭕️ Circle it – and get an explanation.

Whether it's an energy flow, power curve, consumption pattern, or a metric you've never seen before, AI Keeper breaks it down in clear, practical language – turning complex energy data into insights you can actually understand. ✅

No searching. No switching screens. No tech jargon.

Just Circle and Understand. 💡

Because a truly smart energy platform shouldn't just show you data – it should help you make sense of it. 🔋

⚡Less diesel, more solar - sounds good, right? 😎

In off‑grid C&I setups, the real challenge isn't just making solar power. It's making every single kilowatt‑hour count.

Enter SAJ AI DGenius - a predictive energy management brain that forecasts solar output and site demand, optimizes battery SOC, and squeezes more out of every sunny moment.

In a simulated case study of an off‑grid manufacturing site in Kajiado, Kenya, here's what AI DGenius showed it could do:
✅Boost PV self‑consumption from 89.1% → 98.1%
✅Slash PV curtailment from 10.9% → 1.9%
✅Cut diesel charging and improve system economics

How it works:
🔮 Forecasts solar & demand
📋 Plans battery SOC to avoid unnecessary morning diesel charging
🔋 Saves battery room for the noon solar peak
⚙ Sends energy where it's needed to cut diesel runtime

📌 Note: These are simulation results under specific assumptions - not a guarantee of financial or operational performance.

SAJ – Smarter energy, less diesel, happier planet. 💚🔋

⚡Your home battery can do way more than just store energy. 😎

With elekeeper and AI Saving, the SAJ EK90 / EK70 HS5 keeps an eye on your solar, your usage, electricity prices, and battery status - then optimizes everything in real time. Pretty smart, right? 🤖

But here's the cool part: HS5 is VPP‑ready! That means your home battery can join a bigger network, help support the grid, and respond to market signals - all while keeping your home powered first. 🏠🔋

From one home to a whole energy community, the EK90/EK70 HS5 unlocks more value from every stored kilowatt‑hour. 💚

✅ Real‑time optimization
✅ VPP‑ready for grid support
✅ Your home always comes first

SAJ – Smarter energy, happier home. 🔋✨

⚡SAJ CHS3 10‑Unit Parallel Operation Test Successfully Completed at SAJ Factory!

To validate the system‑level performance of the SAJ CHS3, SAJ conducted a 10‑unit parallel operation test at our own factory. The 1.25 MW system features 10 units of CH3 C&I hybrid inverters, with each inverter connected to a 260 kWh battery.

🔹 Key tests completed & verified:
✅ On‑grid ↔ Off‑grid
✅ Off‑grid operation test with load
✅ Diesel generator switching test
✅ Charge & discharge test

🎯 On/off‑grid transition under 400 kW load achieved 20 ms seamless switching.

This millisecond‑level transfer guarantees uninterrupted power for critical industrial loads - delivering reliable resilience for C&I microgrids, backup power, and PV‑storage‑diesel hybrid projects.

SAJ - Engineered for Reliability, Built for Scale.

🇦🇺 Yes, Alex! Congratulations to Alex de Minaur and Team Australia on advancing to the next round of the Davis Cup!🎾

We've stood with Alex on this very court as part of our global brand partnership - and now he's done his part to seal the tie. Same arena. Same energy. And we're so proud to see it.👏

This is what Relentless Energy means to us - it's not just a slogan. It's showing up, point by point, match by match. On court and off. In everything we build. It's about competing on value, on grit, and on being there when it matters most.

Congrats, Alex. We're proud to ride with you. 💚
