Huawei string solar inverter was released in April 2020. The new SUN2000-L1 series ranges from 2kW to 6kW and features ‘dual MPPT’s’ with a wide operating voltage range of 120V to 600V. The new huawei string solar inverter series is a battery ready inverter compatible with the popular LG Chem battery, and now the new Huawei battery system – the LUNA2000 – see full details below. Although it’s worth noting with the LG battery connected the upper voltage is reduced to 495V which limits string lengths to 11-12 panels. This is coincidentally the direct opposite problem facing the main competitor SolarEdge, where the optimised systems have several issues with shorter strings below 7 panels. In comparison the SUN2000L inverters allow very short strings of 4 panels along with the flexibility to function with or without optimisers (more about optimisers below). Oversizing PV is also rated to a modest 1.33 inverter rating depending on panel configuration.
