⚡ The “Lightweight Wonder” for Power Engineers Is Here!

Still lugging around power-frequency resonant transformers weighing several tons to job sites? That’s so last century.

Ultra-Low Frequency High-Voltage Generator—featuring 0.1Hz digital frequency conversion technology. With a capacity of just 1/500th that of a power-frequency unit, the entire system consists of a 4kg controller and a 25kg voltage booster—light enough for a single person to carry. Handles AC withstand voltage testing for XLPE cables, large generators, and power capacitors all in one device.

✅ Fully automatic voltage step-up/step-down, measurement, and protection
✅ Waveform distortion ≤5%; direct sampling on the high-voltage side ensures accurate, unadulterated data
✅ Dual overvoltage and overcurrent protection with a response time

Ultra-thin low-frequency inverters are a “slimmed-down” version of traditional line-frequency inverters. They retain the transformer-isolated design of line-frequency inverters, produce a pure sine wave output, and offer strong overload capacity. They can withstand the starting surges of inductive loads such as motors and compressors, and their reliability far exceeds that of high-frequency models.

⚡️ No more lugging around generators on construction sites!

The 32kWh diesel-lithium hybrid energy storage system puts an end to the old problem of “voltage dropping the moment you start welding.”

The logic is simple: a small 20kW diesel generator slowly recharges the battery, and the lithium battery kicks in the moment the load spikes—as steady as a rock. The generator doesn’t have to burn fuel at full capacity all the time; it automatically shuts down once fully charged, extending its lifespan and cutting maintenance costs in half.

Let’s do the math: traditional generators cost about 4 yuan per kWh, while this system brings it down to less than 1.5 yuan per kWh—that’s a significant savings.

🔋 Lithium iron phosphate (LiFePO₄) cells, with a minimum of 3,000 charge cycles and IP54 protection—built to withstand the elements outdoors.
🔌 Charges via three sources: grid power, diesel, or solar. Separate charging and discharging ports ensure seamless master-slave control without conflicts.
🏗️ Backup power for construction sites, farms, amusement parks, and data centers—one unit does it all.

It’s time to turn the page on the fuel era. Saving fuel means saving money, and saving money means making money. 💰🔋

⚡ 515kWh Microgrid Power Station Officially Launched! 🔋

While others are still waiting for the power to come on, we’re already generating our own electricity.

515kWh energy storage + smart microgrid—this isn’t a sci-fi movie; it’s the reality of 2026. ☀️🔄

☀️ Max out solar power during the day and consume green energy on-site
🔋 Excess electricity? Store it in the 600kWh “super power bank”
🌑 Nighttime, cloudy days, or peak demand? Energy storage kicks in for a seamless transition
🏭 What if the main grid goes down? Zero power outages for critical loads

This is the magic of microgrids—self-balancing, self-regulating, and self-securing.

750V energy storage systems are becoming increasingly common, but many people are still relying on high-frequency isolation solutions to handle high voltages—and this is a potential hazard.

Transient surges on the high-voltage side can easily reach several thousand volts, and the interference resistance of high-frequency topologies simply isn’t up to the task. Thanks to its low-pass filtering characteristics—which are rooted in the laws of physics—power-frequency isolation offers far superior suppression of common-mode noise compared to high-frequency solutions.

Keep these three key specifications in mind: isolation ≥ 4 kV, CMTI ≥ 15 kV/ms, and leakage current < 1 mA. If these three criteria aren’t met, don’t use it in energy storage systems.

It’s 2026—when it comes to interference resistance, the laws of physics are the final authority. 🔌

Phase-split inverters are the true must-have for off-grid systems in North America and Japan.

A single unit with three terminals (L1, L2, N) directly outputs both 120V and 240V. L1 to N is 120V, and L2 to N is also 120V, but there is a 180° phase difference between L1 and L2, so when added together, they total 240V.

What does this mean? Plug your desk lamp and phone charger into the 120V circuit, and connect your air conditioner, water heater, and electric stove directly to the 240V circuit—no transformer needed, no need to parallel two units; a single unit handles the entire house.

The same principle applies to 240/480V systems. In industrial settings, large motors and high-power equipment can be powered directly by 480V, while control circuits and lighting use 240V—a single system supports both voltage levels.

120/240VAC US-Standard Output Low-Frequency Inverter
Attention everyone in the US working on off-grid, RV, or backup power systems ⚡️

Stop buying those inverters that only output 120V.
Your air conditioner, dryer, and electric stove all run on 240V—plugging them in would be a waste.

What you need is a 120/240V Split-Phase Line-Frequency Inverter 👇

🔹 L1-N = 120V → Perfect for lights, refrigerators, and TVs
🔹 L1-L2 = 240V → Directly powers air conditioners and dryers
🔹 Isolated by a line-frequency transformer, with virtually zero leakage current—can handle motor starts
