Solar Battery Controller "EPC8MPPT"
Power generation efficiency is up to 95%! A high-function, high-performance solar controller with MPPT functionality that maximizes power from solar cell modules.
This is a super compact solar battery controller designed in-house. It is equipped with an "MPPT function" that controls the power obtained from the solar panel modules to maximize it according to changes in weather and sunlight conditions. Thanks to the MPPT function, it is possible to charge the battery with 95% efficiency from the power generated by the solar panel modules. After sunset, it automatically shuts down to avoid consuming excess power. <Features> - Charging method: MPPT - Charging method: CC-CV (constant current constant voltage charging) - Wide temperature range (-20 to +45°C) - Power generation efficiency: 95% - Overcurrent protection fuse (low-profile type) - Basic warranty of 2 years (up to 5 years warranty with EP's unique extended warranty) For system diagrams and other detailed specifications and features, please refer to the PDF materials or feel free to contact us.

【Advertised Product! Solar Cell Module Product Catalog Now Available】Everything about the product is clearly explained in one booklet? We are currently offering a free product catalog to deepen your understanding of our products!
We are pleased to announce the release of the product catalog for the PVS Series solar cell modules! This comprehensive catalog includes common information about the series, such as system application examples and system diagrams categorized by equipment usage, as well as detailed information on all nine product lines. Additionally, it features product information for the related product: solar cell controller "EPCM8MPPT-PCB," making it a very informative resource. Since it contains all the necessary information for selection, please feel free to download and review it. In addition to this product, we have upgraded the catalog for inverters and other necessary components for building a system from a flyer type to a booklet type. This catalog consolidates common information about the product series, including product highlights, applications, and system diagrams, along with individual information that varies by product capacity, such as electrical characteristics, derating curves, and dimensional drawings. We encourage you to check it out as well. ▲Note▲ NPB Series: Previously, the catalog was divided into two volumes based on capacity, but we have now consolidated it into one for your convenience. Therefore, the product pages are linked to the same catalog, so please be careful to avoid any confusion.

Orders have started for the highly reliable 5000W off-grid pure sine wave inverter that can be connected in parallel with up to 6 units! Introducing the integrated inverter, the DC-AC inverter 'NTN-5K Series', which combines the functions of an AC/DC charger, DC/AC inverter, and AC bypass.
This time, we would like to introduce the "NTN-5K Series," a highly reliable off-grid pure sine wave DC-AC power inverter with a maximum capacity of 5000W that can be connected in parallel with up to six units. The main feature of the DC-AC inverter "NTN-5K Series" is its built-in "Active Current Sharing Function," which allows for the efficient sharing of the most active current, enabling higher output. This means that it can be connected in parallel with "up to six units," allowing for the construction of larger systems without the need to add other products. For detailed specifications and features, please refer to the PDF document or feel free to contact us. ▲Note▲ For customers constructing a three-phase four-wire parallel system, we will assemble and sell the system. Additionally, for customers considering purchasing a single unit, we kindly ask you to contact us.
