Before diving into the firmware, it helps to understand the hardware. The is part of Huawei's M1 series and is a battery-ready hybrid inverter. Its high efficiency of up to 98.6% makes it well-suited for maximizing solar yield in homes and small commercial environments. The inverter includes two independent MPPT trackers with a high input current of up to 13.5 A per MPPT , making it compatible with high-wattage PV modules. The device comes with built-in Wi-Fi connectivity and can also use optional 4G dongles for remote monitoring through the FusionSolar platform.
