So I purchased the IC-3000 for my trailer last summer. The reason was it was a load sharing inverter that supported the split phase service. First all the documentation will lead you to believe that the unit will work on both legs - it does not! As a inverter or during load sharing, the unit only works on one of the two legs. The second issue is with my AGM batteries the unit will not charge them at the full 120a DC the unit is capable of. When the batteries are low, I can only get around 90a DC at best.
The most important issue with the Go Power IC-3000 is the load sharing does not always work properly. When a large load turns on, it will trip the surge protector in the coach which disconnects the main power. This forces all the load onto the inverter, the problem is the unit will not turn back on the mains. Once the main power has been disconnected by the IC-3000 the only way to get it working is to turn off all AC and DC systems and “reboot” the electrical stystem!
Finally the problem that forced me to remove the unit and return it was it does not properly support monitoring the max shore power. When you dial the IC-3000 remote to say 15a such as when you are driveway surfing, it can and will pull MORE then 15a from the outlet. It seems something is wrong with the way the unit senses AC power and will easily blow past 15a. I have literally melted the 50->15a dogbone adapter because I could not properly limit the input power!
Both the Go Power IC-2000 and IC-3000 have these same issues. I can’t implore people enough to stay from this clearly substandard product! I would recommend for inverter/chargers to stick with a known brand such as Magnum or my personal favorite Victron!
Feel free to hit me up with any questions anyone has!
