What connectors do Huawei string inverters use?
The two Huawei string inverter models under review use Amphenol Helios H4 connectors for the DC inputs, similar to many international inverters models, and micro-inverters installed in the US.
Does PV voltage affect the thermal performance of Huawei solar inverters?
The thermal derating, along with any associated with DC voltage and reactive power should be fully considered when applying the Huawei solar inverters. The derate curves in Figure 10 indicate that the thermal performance of the string inverters is affected by PV voltage.
How does Huawei inverter work?
Huawei utilizes 2 large environmental chambers to provide elevated ambient temperature “burn-in” of the manufactured inverter products. Each chamber can handle 48 three phase string inverter units per burn-in cycle. The ambient temperature inside the thermal chambers is set to 50oC and the units are operated at 43 Amps output current for 4 hours.
How many volts can a Huawei string inverter run?
It should be noted that the data sheet indicates that the inverters can operate down to 200Vdc. Below 560Vdc, the Huawei string inverters will operate off of the maximum power point but details of this operating range were not provided to DNV GL.
Do Huawei inverters need a relay?
DNV GL recommends that all inverters include a means of automatically disconnecting all energy sources in the event of an inverter problem, by including a relay or contactor on the DC side. Figure 9. Circuit Diagram of the Huawei Inverter It should be noted that these units are not-isolated and must be employed with the PV array floating.
What are Huawei inverter manufacturing areas?
The Huawei inverter manufacturing areas can be split into three separate distinguishable portions: Incoming quality inspection and test, PCB assembly, and final assembly and test of the completed inverter systems. The production of the SUN2000-25KTL-US and SUN2000-30KTL-US products began volume production in September 2015.

Traditionally DC power conversion was achieved through a motor generator set, where a motor operating on DC power directly turned a generator to produce the required AC power. The opposite of this, an AC motor driving a DC generator was called a converter, hence the name inverter when applied to a DC to AC gen-set, the name stuck.
