2.1 Appropriate Usage The X-hybrid includes :- Hybrid ready inverter SK-TL which can convert the DC current of the PV generator into AC current for on grid or off grid usage. - Hybrid inverter SK-SU, which can store the energy in the battery for self-use and also can convert the DC current of the PV generator into AC current for on grid or off grid usage.- Hybrid battery management unit (BMU), which can work together with the SK-TL to implement a battery storage system.- X-hybrid E version with EPS can supply the energy from battery and PV generator when the grid is lost.

Note: For SK-TL series , the fuse and battery are not used The CT can be replaced with meter if necessary. The EPS function is only for E version

Induced surges are the more likely cause of lighting damage in majority or installations,especially in rural areas where electricity is usually by long overhead lines. Surgemay be included on both the PV array conduction and the a.c. cables leading tothe building.

Specialists in lighting protection should be consulted during the end use application.Using appropriate external lighting protection, the effect of a direct lightningstrike into a building can be mitigated in a controlled way, and the lightningcurrent can be discharged into the ground.

Installation of SPDs to protect the inverter against mechanical damage andexcessive stress include a surge arrester in case of a building with externallightning protection system (LPS) when separation distance is k ept.

To protect the d.c. system, surge suppression device (SPD type2) should be fittedat the inverter end of the d.c cabling and at the array, located between theinverter and the PV generator, if the voltage protection level ( VP) of the surgearresters is greater than 1100V, a additional SPD type 3 required for surge protectionfor electrical devices.

To protect the a.c system, surge suppr
