Huawei SUN2000-6K-LB0 Hybrid Inverter 6 kW Single-Phase
The Huawei SUN2000-6K-LB0 is the 6 kW single-phase Smart Energy Controller of the LB0 series, the most recent residential generation with integrated storage. It works with the high-voltage batteries LUNA2000-5/10/15-S0 and LUNA2000-7/14/21-S1 (350-560 V DC) and handles up to 6,000 W in charge and 6,600 W in discharge, with the option of charging from the grid.
It has 2 MPPTs with a maximum input voltage of 600 V, a very wide operating range (40-560 V) and a start-up voltage of only 50 V: it therefore produces even with short strings and in low irradiance conditions. The 16 A per MPPT (20 A short-circuit) are compatible with the latest generation of high-current photovoltaic modules. Maximum efficiency of 97.8%, an IP66 body weighing less than 15 kg, built-in WLAN and RS485; the backup function is implemented with the SmartGuard-63A-S0.
