highly integrated energy management system aiming on providing a
smart PV+ESS solution for home use
HRESYS HESS Series Home Energy Storage System is a highly
integrated energy management system aiming on providing a smart
PV+ESS solution for home use. HESS Series has utilized high
performance and high safety Lithium Iron Phosphate Battery plus
reliable and high efficient Battery Management System (BMS) to
achieve a long cycle life application. With integration of
intelligent Power Conversion System (PCS), the system can realize
switching between Off/On-grid modes smoothly and automatically, and
it can be used for multiple complicated environment to provide an
ideal solution for improving energy utilization efficiency and to
be well used to cope with applications like PV self-consumption,
energy time-shifting, emergency power backup, etc.
By absorbing the power from sun radiation, PV panels may generate
DC power. DC power may then be inverted by PCS to AC power to
supply the AC loads, and the residual power may be used to charge
the battery bank. In case there are still excessive power
available, it may also be fed-in grid. In order to reduce the
user’s energy cost, the HESS can also be set for energy
time-shifting according to the peak/off-peak hours
System Power and Energy can be configured according to customer’s
real need by combining more battery modules and inverters. Except
for PV smoothing, PV self-consumption improvement and energy
time-shifting, HESS can also be used as a backup power to ensure a
smooth and reliable power supply for home use.
Through the Web Applications provided by HRESYS, users or system
operators may monitor the HESS operation status and may be guided
to do the maintenance according to the analysis of the data
gathered by the Applications. The Applications may also notify the
system operators the system failures or potential failures and the
operators may take actions on maintenance and repair without
initial requesting by users.
- System Benefits and Advantages
1. Highly integrated system comprises of PV, inverter/controller
and battery bank to facilitate PV power self-consumption,
and the excessive power can then be fed into grid.
2. Advanced battery management system – when there is a power
outage, the system can quickly and smoothly disconnect
to the grid to ensure power supply safety and reliability, and the
PV on-grid output power can be configured.
3.The priority of power supply resources to the loads can be
configured, for example, can be set to PV > battery bank >
Grid,
but if the battery capacity is lower than setting value, the system
can then automatically configure the priority of using PV
power and Grid power.
4. Integrated BMS system can gather battery cell real-time data to
ensure the battery cells’ safety and to maximize the
utilization of battery.
5. Unique and high reliability electrical and structural design by
using vertical installation of battery cells to enhance the
stability of battery.
6. Thermal transmission and heat dissipation have been enhanced in
electrical design.
7. Advanced battery cell algorithm has been utilized on SOC/SOH
estimation.
8. High safety and high-performance Lithium Iron Phosphate battery
cells are adopted to ensure long service life, high
energy density in both measurement and weight and environmental
friendly.
9. Easy installation and easy operation - Plug-and-Play
10. Intelligent control, modular design and human friendly
interface with LCD display.
