Huawei SUN2000-4KTL-L1 4kW Hybrid Inverter Price in Pakistan

Note: 4000 W rated, 4400 VA maximum apparent power, from a recommended array of up to 6000 Wp. Maximum efficiency 98.4% and 97.5% European weighted, which is the figure worth comparing because it weights the part-load running a Pakistani roof actually spends its day at. Battery discharge is capped at 4400 W, so pairing this with a large LUNA2000 will not raise the backup power beyond that. Huawei call this a Smart Energy Controller rather than an inverter, because it is built to run a LUNA2000 battery alongside the array: 350 to 560 V DC on the battery side, 15 A operating current and 5000 W of charge power on every model in the range. Two MPP trackers, one string each, 600 V maximum input, 100 V start, a 90 to 560 V tracking window and 12.5 A per tracker against 18 A short-circuit. Single-phase at 220, 230 or 240 V, power factor adjustable 0.8 leading to 0.8 lagging, THD under 3%. Arc fault protection, anti-islanding, insulation monitoring, residual current monitoring, DC reverse polarity, and Type II surge arresters on both the DC and AC sides to EN/IEC 61643-11. It can charge the battery from the grid. IP65 and rated -25 to +60 degC, derated above 45 degC, which is the figure that matters in a Pakistani summer. Natural convection, so no fan to fail. Nighttime draw under 2.5 W. 12.0 kg on a 365 x 375 x 156 mm case. LED indicators with built-in WLAN and the FusionSolar app, RS485, and optional Ethernet or 4G dongles. Certified to EN/IEC 62109-1 and -2 with IEC 61727 and IEC 62116 for grid connection. Works with the SUN2000-450W-P2 and 600W-P optimisers. Huawei note the array ceiling rises to 10,000 Wp when long strings are fully populated with optimisers.
