Also known as: SCA 100 K T US 480, SCA 50 K T US 208, SCA 100 K T, SCA 50 K T, SCA100K-T-US-480, SCA50K-T-US-208
Category: Inverters
Make: chint
Product level: family

This CHINT Power Systems (CPS) family of three-phase string inverters has two models: the SCA100K-T-US-480 and the SCA50K-T-US-208. The SCA100K-T-US-480 is rated 100 kW at 480 Vac. The SCA50K-T-US-208 is rated 50 kW at 208 Vac. Both ratings apply at power factors from above 0.99 down to ±0.91. Both models accept up to 1000 Vdc at the DC input. Their operating DC input range runs from 200 to 1000 Vdc. The DC/AC ratio is 2, so the maximum PV power is 200 kW for the 100 kW model and 100 kW for the 50 kW model. The maximum AC output current is printed as 120.4 / 132.4 A for the 480 V model and 138.8 / 152.7 A for the 208 V model. The maximum AC overcurrent protection rating is 200 A for both models. The manual includes a section on RS485 communication wiring.
