RSD-α Series

Rapid Shutdown

​The RSD-α series products complies with US NEC 2017/2020/2022/(690.12)

Various methods to shutdown the PV system when needed. such as inverter DC or AC shutdown, control box emergency shutdown, and mobile phone APP shutdown

Intelligent RSD， it's quick and convenient
Designed for the safety of Solar systems, houses, C&I buildings and property's safety.

01

​High-efficiency Rapid-Shutdown

The modules and solar PV system can achieve rapid shutdown within 30 seconds after the PV system is disconnected with Grid or manually switch-off.

03

Compatibility with Mainstream Inverters

It is self - adaptively compatible with various mainstream string - type inverters.

05

Compatibility with 182 & 210 solar modules

It is suitable for mainstream solar modules, and the maximum power of the connectable module is 750W.

02

No Electric Shock risk during system Installation

Before grid - connection, the device is in a closed state, and the output voltage of the module is less than 1V, ensuring that there is no high - voltage DC electric shock risk for installation workers.

04

Simple Installation

It is easy to install. It can be installed on the module frame, racking system with bolts and nuts, or even install on the backside of the module with a special designed holder.

06

Ultra - long Service Life Design

The product design service life meets the requirements of 30 - year use, and 10 - year product warranty been provided, and online warranty extension service are provided.

Notes

① The SOLARMLPE RSD devices adopts a self - developed communication protocol instead of the Sunspec protocol.
② When installing on the back of the module instead of on the frame or racking , a specially - designed holder needs to be purchased separately. The holder is bonded to the back of the module through structural glue or foam tape. For details, refer to the installation manual.
③ After adding AFCI module to the EMS box( S‒Box), the system - level AFCI function is enabled.
④ The RSD meets regulatory requirements, but the RSDdevice cannot prevent fires caused by defects or failures of photovoltaic module or the system itself.
