Huawei SUN2000-215KTL-H3200kW (215kVA) 1500V string inverter, 3 MPPT at 100A

Overview

The SUN2000-215KTL-H3 combines 200kW nominal and 215kVA maximum output at 800V AC with only three MPP trackers rated at 100A each. Its 14 string inputs are split 4/5/5 over the trackers, and every string needs its own input because Y-branch connectors are not allowed. The MPPT range is 500–1,500V with 550V start-up, maximum efficiency is at least 99.0% and European efficiency at least 98.8%. The IP66 unit weighs up to 86kg and uses Staubli MC4 EVO2 connectors.

How it works

Like the SUN2000-215KTL-H0, the SUN2000-215KTL-H3 delivers 200kW nominal and 215kVA maximum output, but it uses only three MPP trackers rated at 100A each, with 4, 5 and 5 string inputs, 14 in total. Tracking spans 500–1,500V, start-up is at 550V and nominal input voltage 1,080V. The AC output is 800V, 3W+PE, with 144.4A nominal and 155.2A maximum current and harmonic distortion below 1%.

Three DC switches group the inputs: routes 1–4, 5–9 and 10–14. They open automatically when the inverter detects a reversed string or current backfeed; once the fault is cleared, the RESET buttons must be pressed before switching on again. String fault monitoring, DC insulation resistance detection, a residual current monitoring unit and Type II surge arresters on the DC and AC sides are integrated.

Installation and compatibility

Every string must have its own DC input: individual strings must not be paralleled or combined with Y-branch connectors, or the inverter may be damaged. Input PV1 must always be used, and the quick guide lists which inputs to populate for 9 to 14 strings; unused inputs are closed with sealing plugs. A measured string voltage above 1,500V means the string has too many modules and must be shortened.

DC cables are 1500V copper PV cables to IEC 62930 or EN 50618 with 4–6mm² conductors, and aluminium DC cables must not be connected directly. AC cables can be copper of 50–240mm² or aluminium of 70–240mm²; on some versions OT/DT lugs up to 400mm² fit single-core cables. The housing measures 1,035×700×365mm, weighs up to 86kg and uses Staubli MC4 EVO2 DC connectors.

Monitoring and settings

Communication uses RS485 or MBUS power-line communication, with WLAN and the app for local commissioning and a USB port for maintenance. Smart I-V curve diagnosis is supported. The inverter operates from -25°C to +60°C and without derating up to 4,000m, cooled by smart air cooling. The datasheet does not list grid-code certificates, so confirm those for the country of installation with Huawei.
