In June 2022, Megarevo provided 20 MPS0030 Hybrid inverters to 20 local sites in the coal development area of Yulin, Shaanxi Province. Each site consists of a 10kw generator, an MPS0030, 15.8kwp PV and 150kwh GEL battteries, which together form an off-grid microgrid to provide clean power to the local coal mine drainage pipeline's regulating valves and electric valves, effectively promoting the recycling of coal mine drainage.
