From June 29 to July 2, 2023, under the guidance of the National Energy Administration, the Shenzhen Municipal People's Government and the China Electricity Council, the 2023 International Digital Energy Expo hosted by China Southern Power Grid Co., Ltd. was officially opened in Shenzhen Exhibition Center. As a new energy integrated solution provider. Yotai brings various products and solutions to the expo.

Based on the design concept of "Safe, Simple, Smart", Yotai presented its comprehensive energy cloud platform and diversified ESS solutions, including residential green energy solution, green transportation solution, smart ESS solution.

(1) Comprehensive Energy Cloud Platform

Yotai created the comprehensive energy cloud platform that integrates AI and energy based on the IoT, big data and blockchain technology.

The cloud platform integrates energy strategy management, operation and maintenance testing and monitoring. While ensuring energy asset safety, improving asset utilization efficiency and reducing asset operation and maintenance costs, data fusion can realize power market services such as multi-energy complementary, VPP, carbon trading.

(2) Residential Green Energy Solution

Yotai Residential Green Energy Solution are mainly composed of three parts: hybrid inverter, energy storage battery and comprehensive energy management system.

The hybrid inverter has the functions of PV grid-connected inverter and PCS. On the one hand, it connects to PV power generation to complete the DC to AC conversion. On the other hand, it  can connect the energy storage battery, control the battery charge and discharge, and perform AC/DC conversion.

Energy storage battery is the core of residential energy storage and the cost accounts for more than 50%, of which the main function is to charge and discharge under the control of the inverter and comprehensive energy management system to achieve the time shift of energy.

The comprehensive energy management system is the brain of residential energy storage, integrating energy strategy management, operation and maintenance detection and monitoring in one, while completing the smart operation and maintenance of the system, so as to help users realize the most economical and effective application of energy.

Yotai Residential Green Energy Solution can greatly reduce the cost of residential electricity, helping families to achieve zero electricity purchase goals.

(3) Green Transportation Solution

Yotai Green Transportation Solution is mainly composed of three parts: PV system, ESS and EV charging system.

The PV system adopts rooftop PV and parking garage PV, and connects multiple PV modules to the PV DC busbar, which is connected to the grid through the PV inverter. The ESS adopts all-in-one design and integrates lithium iron battery, BMS, PCS, EMS, temperature control system and fire control system in one that can provide users with services such as peak-shaving, power capacity expansion, capacity cost management and backup power supply.

EV charging system works based on the communication between charger and car battery management system; the power converter can adjust the DC charging power online, and the charger can display the charging voltage, charging current, charging amount and charging cost.

By combining "PV", "ESS" and "EV Charging" to form an comprehensive system, Yotai Green Transportation Solution can improve energy efficiency, optimize the configuration of energy. 

The ESS can store energy at night and supply power together with the grid by discharging during peak period, to solve the "slow charging, difficult charging" and other problems at the same time, which also realizes the functions of peak-shaving, saving power distribution cost and increasing capacity.

(4) Smart ESS Solution

Yotai Smart ESS Solution can be customized based on the various needs of power generation side, grid side and user side.
