Huawei SUN2000-25K-MB0 Hybrid Inverter 25 kW Three-Phase
The Huawei SUN2000-25K-MB0 is the 25 kW three-phase Smart Energy Controller of the MB0 series, designed for large homes and small commercial users with storage. It has 2 MPPTs with 4 inputs in total, a maximum voltage of 1,100 V, an operating range of 200-1,000 V and high currents (30 A per MPPT with two strings, 40 A short-circuit), for a recommended photovoltaic power of up to 37,500 Wp.
The storage interface features two battery terminals for the LUNA2000-5/10/15-S0 and LUNA2000-7/14/21-S1 (600-980 V DC), with charging power up to 21 kW on a single string and 25 kW on two strings, and discharging up to 25.0 kW. Maximum efficiency is 98.4% (98.2% European); Smart Air Cooling and the IP66 rating allow outdoor installation. Up to 3 units in parallel with Smart String ESS. Certified according to CEI 0-21:2020-12.
