[Shocking] How about grid storage batteries priced around 30,000 yen/kWh?

[Update] A water-cooled energy storage system has been developed to replace the conventional air-cooled systems, maximizing efficiency and stabilizing operation!

A water-cooled energy storage system has been developed to replace the conventional air-cooled systems, maximizing efficiency and stabilizing operations! This product, marketed under the name "TAOKE's Pride," is offered in an outdoor weather-resistant container storage style. Therefore, as long as the necessary foundation, piping, and wiring are prepared on-site, it is a very easy-to-install all-in-one package that only requires placement. The output can be customized in 50kW increments, and the capacity can be customized in 221kWh increments. For example, configurations such as 100kW/221kWh, 200kW/442kWh, 300kW/663kWh, 400kW/884kWh, and 500kW/1105kWh can be freely customized for both inverter output and storage capacity. Additionally, with "DC coupling," which eliminates the need for a PV inverter and simplifies overall control, the system becomes even more robust. The battery cells use safe and reliable lithium iron phosphate batteries from CATL, employing a water-cooled system that maximizes efficiency and stability, while also meeting stringent certifications such as UL9540A, which boasts world-class flame resistance.

It is a system for self-consumption in industrial facilities that maximizes power generation in accordance with the size of the load. It is also compatible with third-party ownership.

For a long time, there has been no optimal solution for energy systems aimed at industrial use. There are several reasons for this, but the most significant one is undoubtedly its complexity. Scheduling all the dates for 365 days a year, sometimes as operational days and sometimes as holidays, can be cumbersome when dealing with sudden breaks or when trying to respond to unexpected loads. Even after installation, many complaints arose about the solar power generation systems that were supposed to be implemented, as they often "stopped completely" and did not perform as expected. This is because, in a complete self-consumption system for industrial facilities, there is a mechanism that requires stopping generation to avoid feeding back into the grid. This system requires almost no difficult analysis or simulations during the implementation process, as it automatically follows the loads within the facility. Therefore, not only is maintenance after installation almost unnecessary, but it is also an exceptionally efficient solution. For single-phase loads, it provides nearly perfect load following, and even for three-phase equipment, it offers approximately 80% load following with basic maintenance-free operation. I believe this system represents the best solution required in the era of self-consumption.

The solar power generation system that can be connected with just one panel not only allows for flexible layout design but also provides peace of mind with its RSD function in case of a fire!

While solar power generation systems are a very good option for addressing global warming and improving energy self-sufficiency, are you carelessly placing modules all over the roof of your home, which should be a lifelong treasure? It may be that both sellers and buyers believe that a system that generates a lot of electricity creates a win-win relationship, but is the design of your home’s roof, which should be a precious treasure, being sacrificed? Even in such cases, you can be assured with this NEP Micro Inverter. Even if the roof faces east, west, or south, and the number of modules does not match for each direction, this Micro Inverter optimizes power generation for each individual module, allowing you to install a solar power generation system without sacrificing design, keeping your roof smart and stylish. Moreover, it is equipped with a "rapid shutdown function" that allows you to cut off power at the module level in the event of a fire, a feature that has become standard in Europe and the United States, where it is already impossible to install on roofs without this function. This is a solar power generation system that can be interconnected with just one module!

Replacing the conventional fixed type, the 5,120Wh storage system "AP500" has been born, which requires neither a foundation nor construction.

Despite being a portable power storage device, it boasts an outstanding capacity of 5,120Wh. With this, there is no shortage for BCP measures in your home, facility, or office, replacing conventional stationary systems. Not only is it already cost-effective, but it also offers exceptional cost benefits since no foundation or installation is required. The housing with wheels is versatile for any lifestyle, and its stylish appearance adds aesthetic value just by being there, making it a formidable competitor to stationary storage systems with its portable 5,120Wh capacity and 2kW output. Furthermore, since it is used indoors, there are no restrictions on usage even in difficult-to-install areas like "heavy snowfall regions" or "high salt damage regions"! The body, which evokes a near-future image, comes standard with a touch panel, allowing for easy control and management. A stylish power storage system with no compromises in any aspect. To leverage the AP500's greatest advantage of "no foundation or installation required," we have created an "initial setup manual" to ensure that even without electricians or contractors, initial setup is straightforward. If you are interested, please let us know.

The birth of a supreme storage battery with a capacity of 2kWh, an output of 2kW, a PV input of 700W, charging functionality for EVs, dual wireless charging capabilities, and lithium iron phosphate.

The ultimate excellence that surpasses everything is here. With an astonishing capacity of 2kWh, a rated output of 2kW, and a PV input capable of up to 700W, it even includes a charging function for EVs. The wireless charging feature on the top can accommodate two devices, all while using safe and reliable lithium iron phosphate lithium-ion cells. This marks the birth of the supreme hybrid portable lithium-ion storage battery. Surpassing the concept of portability, it is an overwhelming presence that transcends everything and silences all. In the Japanese version, it uses safe and reliable lithium iron phosphate lithium-ion cells and comes standard with a touch panel, demonstrating thoroughness. The extraordinary specifications of 2kWh capacity and 2kW rated output in a portable form are proof that it has already reached the farthest realms. Nothing more, nothing less—what matters most is that it is the “AC200P,” the one and only storage battery. Please experience this greatness for yourself.

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence. [Table of Contents] ■ Why is underfloor checking necessary? ■ Checkpoints to confirm after a typhoon or heavy rain ■ Responses when damage is discovered ■ Points for preventing recurrence ■ Suggestions from Seihou Products ■ Summary Please be sure to read the [related materials] and [related links]. ↓ ↓ ↓
