Frequently asked questions

What size array does the Huawei SUN2000-3-6KTL-L1 suit?

The Huawei SUN2000-3-6KTL-L1 designation spans a family from 3 kW to 6 kW, and the figures recorded for this entry are 6000 W of nominal AC power with the same 6000 W as its maximum. With no headroom above nominal, a domestic array of about that size, modestly oversized on the DC side, is the right match.

What does the 90-560 V MPPT range of the Huawei SUN2000-3-6KTL-L1 mean for string design?

The Huawei SUN2000-3-6KTL-L1 tracks from 90 V to 560 V and tolerates 600 V of maximum DC input voltage. Starting to track at 90 V is unusually generous, so even a short string wakes the inverter early in the morning, while the 600 V ceiling caps string length at the coldest expected temperature.

How many MPPT channels does the Huawei SUN2000-3-6KTL-L1 have?

The Huawei SUN2000-3-6KTL-L1 has two independent MPPT channels, each accepting up to 12.5 A of DC input current. Two trackers let two roof planes of different orientation or shading be optimised separately, while 12.5 A is sized for a single string per channel rather than for a paralleled pair of strings.

How efficient is the Huawei SUN2000-3-6KTL-L1?

The Huawei SUN2000-3-6KTL-L1 is rated at 98.4 percent maximum efficiency and 97.8 percent European efficiency. The European figure is the weighted one, reflecting a realistic year of partial and full load, so roughly two percent of the DC energy the array produces is lost in conversion, a strong result for a domestic unit.

What grid connection does the Huawei SUN2000-3-6KTL-L1 need?

The Huawei SUN2000-3-6KTL-L1 is single-phase and is specified for several nominal grid voltages, 220 V, 230 V or 240 V, at either 50 or 60 Hz, so the same hardware covers different national grids. Harmonic distortion is quoted at 3 percent, within what network operators normally expect from domestic generation.

Can the Huawei SUN2000-3-6KTL-L1 be mounted outdoors?

The Huawei SUN2000-3-6KTL-L1 is a string inverter rated IP65 and specified from -25 to +60 degrees Celsius, so an outdoor wall position is within its declared limits. At 12.0 kg it is an easy one-person lift, which makes siting it beside the meter or on an external house wall straightforward.
