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.

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.

  • Product news

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.

Maximize power from solar cell modules and be a key player supporting solar systems" With MPPT functionality, the power generation efficiency is 95%! Introducing our self-designed ultra-compact solar cell controller "EPC8MPPT.

  • Product news

The power generation efficiency refers to "the ratio of energy (light) received from sunlight by the solar cell module that is converted into electricity." The higher the efficiency, the greater the amount of power supplied, which can enhance the stability of the supply. Additionally, this product is equipped with MPPT functionality, allowing it to maximize and extract power from the solar cell module under various weather conditions, making it a key player in supporting solar power systems. By connecting this product between the module and the battery, it is possible to charge the battery with 95% efficiency. Furthermore, the compact design of the product allows for easy installation, which can reduce the time and costs associated with installation. This product is also compatible with the newly launched DC-AC inverter "NTN-5K" system, so we would appreciate it if you could check that as well. For system diagrams and other detailed specifications and features, please download the product page or catalog, or feel free to contact us.
