My Solis 3 phase inverter.

I had a 3 phase 15kW inverter installed January 2019 and it failed in early June. I am still waiting for it to be repaired on 25th of July. It is very disappointing as at first it worked well.

Never been called out to a broken one

I have been working in the solar industry for 8 years and have replaced meany inverters. The ones that I found most reliable. I have replaced two solar edge inverts and three sma but no solis inverters they are a lot cheaper than solar edge and sma, easy to set up, good efficiency you can also optimise only the pannels that have shading I always advise customers to buy solis
