Overview
The Huayu hybrid inverter HYH-8K-NA with nominal AC output power 8kW can work with a battery bank as backup power
to make the best use of time-of-use policy or to keep a continuous power supply in case of grid outage or poor wind turbine/diesel generator performance, which may help end users maximize self-consumption and enhance energy
independence.
Features
Work Patterns
With an intelligent control of the flow of energy, the HYH-8K-NA hybrid inverter is designed to shift the working
modes of a smart load system swiftly among on-grid, off-grid and backup pattern, which enables end users to obtain a financially advantageous electricity bill and stable power supply thanks to its capabilities of zero export,
peak shaving and UPS.
Backup Power
HYH-8K-NA is compatible with 48Vdc low voltage Li-Ion or Lead Acid battery bank(battery voltage range 40-60Vdc).Backup power capacity is a maximum of 8000 watts and it takes a seamless switchover(UPS)within 10ms upon
a grid outage.
Safety
The inverter integrates both ground fault protection and arc fault protection(AFCI).
Parallel Extension
A Huayu energy storage system can support both single phase and three phase
parallel configuration with a maximum of 10 units of HYH-8K-NA inverters for either hybrid or AC-coupled applications.
Smart Monitoring
The Huayu Portal smart monitoring platform provides real-time operating status and historical data including general
data of solar power generation, discharge backup power, load consumption and electricity feed into the grid.
