Everything is updated with the latest firmware and I have tried a second new quattro to just test if the issue is in the unit itself.
When I set the input limit. It works fine, going over to powerassist when the amps increase. I have pulled between 600w-7500w of load with no issues using an array of heaters, lights and general loads like fridges. The inverter works fine with high loads and adding shore power and for the most part, works perfectly.
The boat had 3 different A/C units onboard. Each is about 1000-1500w
But, if I start 1 A/C module, there is a 50/50 chance that it keeps to the input current limit.
When I start the second A/C unit. No chance. It pulls a crap ton from shore power often blowing the fuse.
Input Limit set to 5 amps ~ 1100w and I'm using 1500w to run loads. Powerassist is happening on the diffence.
Start the 2 A/C units, Total load goes to 3000w, input power goes to 2700w completely ignoring the input limit until Iv turned most things off on the boat giving it a little time at low load.
