Hi all. On 14th November 2018 I installed 2 Hoymiles Mi 600 micro inverters along with 4 X 325w panels from Artsolar. I couldn't have wished for a better, easily installed and maintenance free system. With the monitoring wireless system I have generated 690 Kwh to date (4. 4. 2019). It gives me the greatest of pleasure to know that in this period I have reduced my Eskom intake by one third and will pay the system off in 4 years at current rates and even quicker when they increase. 4 more panels and inverters are soon to be purchased. Highly recommended . Oliver Hart, Pinetown.
