RESS HVG1 high-voltage home LFP battery
Country: China · Model: RESS HVG1
The RESS HVG1 high-voltage home battery consists of modules based on cobalt-free lithium iron phosphate cells, which are stacked in a column on the floor. The IP65 case is not afraid of dust and splashes, so the battery is placed in the garage, corridor or boiler room of a private house together with a high-voltage hybrid inverter.

Description
The modules connect to each other through internal connectors, so there are no external power jumpers or cable loops between the units. Each next module is simply placed on the previous one, so there is no confusion over the polarity of jumpers on site. The high battery voltage lowers the current in the cable to the inverter at the same power, so the wire section and the losses in it are smaller than in low-voltage 48 V systems. The cobalt-free LFP chemistry resists thermal runaway, and for a battery standing in a residential house this is the main argument. The intelligent BMS monitors the state of the modules and has multi-level protection. Class IP65 means complete dust-tightness and protection against water jets, so the case withstands wet cleaning and splashes.
How to choose
The number of modules in an RESS HVG1 column is chosen to match the battery input voltage range of your hybrid inverter, so this parameter is checked before ordering. For an inverter with a 48 V battery bus this battery is not suitable, and then the NESR48100 module of 4.8 kWh with expansion up to 76.8 kWh is considered. The wall-mounted RESS LVG1-B5.4 has the same IP65 class and expands up to 32 kWh, but takes a wall rather than floor space. This range is not intended for server room UPS units, where 512NESP racks of 512 V are used.

FAQ
How does the RESS HVG1 differ from low-voltage 48 V batteries?
The HVG1 works with high-voltage hybrid inverters, so the current in the cables at the same power is lower than in a 48 V system.
Can the RESS HVG1 be installed in an unheated garage?
The IP65 case is protected against dust and water, so a garage is suitable as regards humidity. The operating temperature range for an unheated room must be clarified separately.
How are RESS HVG1 modules connected to each other?
Through internal connectors, without external cables between modules. The modules are stacked one on another in a column on the floor.
Is there cobalt in the RESS HVG1 battery?
No, the battery is built on cobalt-free LFP chemistry. Lithium iron phosphate cells are less prone to overheating than nickel-based lithium-ion compositions.
What management system is fitted in the RESS HVG1?
An intelligent BMS with multi-level protection that monitors the state of the modules in the column.
