For large-scale PV grid-connected power generation system, in order to reduce connection cable between inverter and PV components, easy for maintenance and improve reliability, normally add DC combiner box between inverter and PV components. Aotai PV array lightening protection combiner box is designed for this purpose, it can work with Aotai inverter to combine complete PV power generation system. With PV combiner box, user can connect some PV components with same standard into 1 PV module string in parallel according to inverter input DC voltage range, and connect some PV module string to PV array lightening protection combiner box, passing through lighting protections and circuit breaker, then output, this makes convenient for later inverter to connect in.

For large-scale PV grid-connected power generation system, in order to reduce connection cable between inverter and grid, easy for maintenance and improve reliability, normally add AC combiner box between inverter and grid. Aotai AC combiner box is designed for this purpose, it can work with Aotai inverter to combine complete PV power generation system. With AC combiner box, user can connect some inverters with same standard into AC combiner box in parallel according to inverter output AC voltage range, passing through lighting protections and circuit breaker, then output, this makes convenient for later combiner device to connect in.

This MPPT controller is suitable for wide voltage range, adopts Germany power module, and has more stable output. Protection classs is IP65 and suitable for outdoor severe environment.

These inverters adopt modular design. They have LVRT/ZVRT function and can cope with various grid conditions. Power factor is from 0.9 leading to 0.9 lagging.They enjoy active and passive anti-islanding protection.
