PV Relay

SPECIAL

PTG, a group of experts with more than 20 years experiences, devotes itself in producing reliable and excellence relay products. Its high standard testing lab enables full set of type tests and reliability tests according to UL 508, EN 61810, GB 21711, and the products are certified by third party authorities, such as UL, TUV, CQC.
SPECIFIC

PTG cultivates the PV industry and creates a full range of solutions for PV inverters. We collect and combine the practical applications from industry for innovation and optimization. The products have the characteristics of high load current, large contact gap, low heating temperature rise and so on, which makes the application environment of PV inverter broad.
SMART

Patented automatic production line realizes the whole process without contact, so as to ensure the high efficiency and consistency of production. Apart from ISO 9001, tailored ERP system and on-site real-time data acquisition system closely monitor all details and processes from incoming materials to shipment, so as to realize accurate pre-warning and traceability.
