June 10, 20206 yr I have tho Hoymiles MI-600 micro inverters with four panels on my roof. Installation year ago was easy and the small system has since been saving me on my bill every month. However, readings I took this morning indicate the system is no longer contributing. Switching almost everything off in my house midday still showed me I'm using some municipal power. I have not purchased or installed a DTU. Any suggestion on how to trouble shoot what exactly might be wrong? I read the inverters are 'fuse-less' and I'm in the dark. Any reliable affordable installers in Pretoria that have worked with Hoymiles micro inverters?
