These guys were awesome! Extremely helpful and happy to take the time to explain how things worked. Ill definitely only be purchasing victron components from them in the future
This 5 star review is more for the guys at Jonsson Tech than the inverter. This particular inverter is 230v output which is not correct for my van / rv here in the USA.
The Jonsson brothers saved my project. After receiving a faulty inverter from Ecoworthy, and having no time left to get a replacement, I called several Victron distributors and only Jonsson had the inverter I was looking for in stock. They overnighted it to me but Fedex got it lost. Jonsson had ANOTHER inverter in stock and I drove up to Houston to get it. Craig not only got us the inverter but took the time to help is finish the install and program it. The install was flawless and has worked perfectly since then. I was absolutely blown away by their product availability and service they provided with the sale. Absolutely amazing. If you are considering the high quality Victron line, call these guys first and save time and headaches.
Even the other Victron distributors and installers I called said if I wanted same day service to call Jonsson. I listened and am very glad I did, they will be my only call on all future projects.
Great product!!
