    Sumpdirect service and delivery was top notch, will certainly buy from them again. As for the inverter, this is the third one in 6 years. I replaced the original which was under warranty, but was told by ION that they wouldnt be ace it again. 3 years later, the inverter started passing to much wattage and overcharged their $400 battery to the point it got swollen. Bought anew one because i didnt to change the whole set up but not acceptable for a product worth several thousand dollars. You’ll find other people with same issues in youtube. I would suggest checking another system or be ready to replace it often.
