    SOLAR OPTIMIZING
    If the site is generating more solar power than it needs, the excess is stored for future use.
  • product_khess07
    GRID INTERACTIVE
    When the grid goes down, the unit provides solar backup power to the site.
  • product_khess08
    PRICE RESPONSIVE
    When electricity prices are high, the unit dispatches both solar and stored power to reduce consumption.
  • product_khess09
    DEMAND RESPONSIVE
    As energy consumption patterns change, the unit adapts to serve the demand and “shape” the load.

Features

- RENEWABLE VALUE ENHANCEMENT

Kokam’s Home Energy Storage System (KHESS) provides a number of different functionalities. Its peak shaving function allows the user to save expenses by utilizing stored energy at peak times. The functionality which allows the integration with various renewable energy sources is one of the key advantages. It changes the users’ paradigm from the conventional way of using energy only on-demand, to the next generation, where users can control time and amount of use so that the time-value of energy can be optimized. The KHESS will contribute to enhancing the quality of the environment by reducing usage of fossil fuels. Also, the UPS with KHESS function provides energy for users during power outages.

- SOFTWARE

Kokam’s proprietary software, with a simple and convenient User Interface design, helps users to easily access and control KHESS. The ‘Smart Scheduler’ function, allows user to set up the operation modes at your desired time. KHESS has been supplying a fast growing market for individual households and small communities to enable efficient management of their electricity. New functions have been introduced to analyze user’s electricity consumption pattern and automatically select the most efficient operation mode. Also, remote control option is now available for KHESS.

- RELIABILITY

The smart BMS is designed to ensure the safety. It manages the operation modes in the most effective way. with its functions to monitor the voltage and temperature of individual cells, together with its built-in, protective units such as circuit breaker, contactor, and fuse for the highest safety standards.
