Traditional hybrid electricity generators typically use diesel or petrol for fuel. To protect the environment, hybrid inverter systems offer the best solution. However, for such systems the battery quality is very important to guarantee safety and reliability. 

Solution

KSTAR ‘s BluE-S-5000D series is the most up-to date all-in-one single-phase storage product,  providing a safe, smart and high efficiency solution for residential applications, according to the company. To offer optimal performance and a long-life span for customers, the BluE-S-5000D series is an AC coupled all-in-one CATL battery module with a KSTAR inverter, with low maintenance and easy installation. TheBluE-S-5000D series includes a 5-year product and 10-year performance warranty with 24/7 monitoring via the ‘KSTAR Cloud’ app. Moreover, to offer customers a fast response and uninterruptible power supply, the single-phase hybrid inverter features an intelligent modular design and online monitoring  via the ESS app, as well as a programmable time of use tariff in certain countries – charging at night at off-peak then in use during the expensive peak period in the afternoon.

Applications

The BluE-S-5000D series is specifically designed for PV self-consumption, back-up power, fuel saving solutions, battery expansion, load shifting and off-grid solutions.
