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.

For example, a lithium battery that has been used for one year and a brand new lithium battery are mixed on the same PCS machine.

No, due to the characteristics of lithium batteries, different batches of lithium batteries have different battery capacity and internal resistance, and the consistency is very different. Using them together will cause voltage imbalance and current uncontrollable problems.In severe cases, it will cause safety accidents such as fire or explosion of the lithium battery, so it cannot be mixed.
