Smart switch(Limiter)
Thinkpower smart switch is zero-export power control device to limit the excess power feed into grid, it could increase your PV power self-consumption.

smart switch is thinkpower's Energy management solution for the solar system, which not be allowed to export the pv power into the grid, or limit the power that can be exported to a specific limit.

1. Feed-in Limitation
•  Export limitation is integrated into the inverter firmware - install only an energy meter
•  Fast Response Time - ensuring that even with rapid changes in load consumption and PV production the exported power does not exceed the limit
•  Failsafe Operation - the operation is designed to guarantee that the exported power will never exceed the preconfigured limit under any fault  

Thinkpower Inverter as Power Manager 
•  Export limit can be configured by Thinkpower if required by local utility, and can be locked after setting to prevent unauthorized configuration changes
•  In a multi-inverter system, one inverter will serve as the energy manager 
•  Installed Thinkpower inverters can be firmware upgraded with the export limitation option
