Status: active
Also known as: SCH 350 KTL, SCH 350 KTL DO US 800, SCH350KTL-DO/US-800
Category: Inverters
Make: chint
Product level: family

The CPS SCH350KTL-DO/US-800 is a CHINT Power Systems three-phase string inverter for 1500 V PV arrays. It connects to an 800 Vac, 60 Hz grid. It delivers up to 350 kW (350 kVA) and up to 253 A of AC output current. It has 15 MPP trackers, each with two non-fused DC inputs, and each tracker clips at 40 A. The MPPT voltage window is 880 to 1300 Vdc. The inverter operates on DC input from 500 to 1450 Vdc and starts at 550 Vdc. Peak efficiency is 99.00% and CEC efficiency is 98.50%. Power factor is above 0.99 and can be adjusted to ±0.8. It has Type II surge protection on both the DC and AC sides, and load-rated DC switches. Firmware upgrades are done by contacting CPS Customer Service. Fault codes include CommErr (communication error), ExtFanErr (cooling fan failure), CfLowErr (flying capacitor voltage too low) and Fault0110 (bus imbalance). For CfLowErr, remove the branch with the lowest input voltage. For Fault0110, raise the DCI limit first, and replace the inverter if the fault does not clear.

<!-- review notes

sentence 1: support check: partial - 1500 V, three-phase, 800 Vac, 60 Hz are supported, but manufacturer CHINT and 'string inverter' are not stated.
sentence 1: review: partial - The table supports 3-phase, 1500 V, 800 Vac and 60 Hz, but it does not name CHINT Power Systems or say string inverter. -->
