Small energy storage 3-12 kW

"MOBEL" Company has developed low power Energy storage on "Liotech" lithium-ion batteries.

The Energy storage is multi-inverter with integrated recharger and funded component based on lithium-ion batteries (LIB). Funded component of the solution includes a regular battery Management System (BMS), which provides continuous monitoring of the cells status and the connection with charging inverter.

 

 

Recommended for use

  • In the absence of centralized power supply;

  • In case of loadshedding and shortfall;

  • With a lack of available capacity;

  • In case of energy accumulation in the system with renewable energy;

  • In case of energy accumulation from self-contained supplies (fossil generators), reducing noise emission and increasing the life cycle of the generator.

Solutions features

  • Input voltage range set by the user (without using battery power, typically 175V - 250V) and provides additional protection of the equipment;

  • The wave shape of the output signal is 220 V - pure sine;

  • Peak capacitance (5 seconds) is twice more than the nominal capacitance;

  • Can be used as a UPS (with conform software);

  • Ability to connect with computer for monitoring and programming;

  • With the availability of a bypass (automatic translation 220 V, even in emergency cases);

  • Russian menu suitable for input parameters;

  • Fans with adjustable speed for quiet operation;

  • Automatic shutdown in case of overloading and overheating.

Solution benefits

  • Higher capacity compared to the decision on the basis of lead-acid batteries with the same dimensions and weight

  • Long service life (up to 20 years)

  • Low operating costs;

  • Ability to automatically increase the power grid during peak loads;

  • Ability to work in a 2-tariff treatment to save energy;

  • With the availability Integrated battery management system (BMS)

  • High quality of electric current.
