With the increasing pursuit of power generation efficiency of photovoltaic power station, the voltage on the DC side of photovoltaic power station has been gradually raised. In the early stage, the maximum DC voltage of 600V inverter has been replaced by 1000V voltage, and even raised to 1100V. There is no doubt that the high voltage on the DC side of the photovoltaic system will reduce the line loss and improve the system efficiency. Therefore, the current 1100 system scheme has become the first choice for large-scale photovoltaic power stations. We believe that most of the distributed photovoltaic power stations are household photovoltaic or photovoltaic power stations installed on the roofs of various buildings. They are closer to people's daily life. They are usually connected to the user side power grid with low access voltage. In addition to pursuing the power generation efficiency of photovoltaic power station, the more important thing is safety. The system scheme below 1100V shall be adopted as far as possible. High efficiency inverter with low starting voltage and wide MPPT range shall be selected.

In the whole photovoltaic system, the DC side voltage is usually as high as 600-1500vdc. Due to loose contact, poor contact, damp wire, insulation rupture and other reasons, it is very easy to cause DC arcing. The high temperature generated by the arc is very easy to lead to fire when the adjacent substances reach the ignition point, that is, DC arcing is a potential safety hazard. AFCI function by identifying the arc fault characteristic signal in the circuit, AFCI will disconnect the power supply before the arc fault develops into fire or circuit short circuit, which greatly increases the system safety.

In case of shielding and poor connect in the solar plant, the I-V curve of panes will be abnormal. The system will judge the problems in the solar plant, by detecting the I-V curve of photovoltaic array, and automatically give relevant operation and maintenance schemes. Compared with traditional maintenance such as visual observation, it is more accurate and faster. It is more convenient and economical without purchasing expensive operation and maintenance equipment.

XG seires design based on 1100VDC level,suit for new 13A current panels.And have some advanced features:I-V scan,bluetooth，AFCI,night SVG,etc.

XN series can work well without battery, the solar panel output can drive load, but when load power is bigger than solar panel output, inverter will alarm.

The power of off grid inverter shall be confirmed according to the user's load type and power.
The component power shall be confirmed according to the user's daily power consumption.
The battery capacity is determined according to the power consumption of the user when there is no sun, because photovoltaic power generation can be used directly to the load without power storage during the day.

XNPIII series when use more than three unit supporting parallel into three-phase 380VAC output. And support unbalanced configuration, such as one of phase has 15kw capacity, the other two phases are 5kw.

XNPIII series inverter have parallel function.Support max 9 unit parallel.（Need purchase parallel kit）

Yes,IP54 can be customized for PCS and lithium battery cabinet.
