The Huawei SUN2000-25KTL-US and SUN2000-30KTL-US are transformerless three-phase string inverters. They are rated at 25 kW and 30 kW of output power. Both models accept up to 1,000 V DC at the input, and their full-power MPPT window runs from 560 to 850 V DC. Each MPPT takes at most 25 A. The maximum continuous AC output current is 33 A on the 25 kW model and 40 A on the 30 kW model. The 25 kW model lists a maximum efficiency of 98.6% and a CEC efficiency of 98.0%. Built-in protection includes a DC input switch, reverse polarity protection, insulation resistance detection, PV string fault detection and Type II surge protection on both the DC and AC sides. The inverter has an arc fault circuit interrupter (AFCI) to UL 1699B Type I. Its alarms include DC Arc Fault and AFCI Self-Check Failure. All units support RS485 communication, and PLC is an option on some variants. Only one of these modes can be used at a time, so do not connect the RS485 cable when PLC is used. The DC connectors are Amphenol Helios H4, and the enclosure is rated Type 4X.

review note: support check: partial - The passages say AFCI is to UL 1699B Type I. They do not say the inverter is certified.; review: partial - The spec row lists AFCI to UL 1699B Type I for both models, but it never says the inverters are certified to that standard.
