Within a year the previous inverter (omnik solar) broke down 3 times, they repaired it 2 times but after the 3rd time the inverter was completely dead, got a refurbished inverter (solis) after I brought the broken inverter, good service but had to e-mail a lot and wait a long time for an answer (weeks), when the inverter broke after the 3rd time, I started calling and after calling and exchanging the inverter 2 times it was settled, 4 stars for the long wait for the answers via the mail.
