Problem with Quattro 48/5000 Power Assist

My Quattro 48/5000 is connected to AC 1 with a Honda 2000i –AC1 current limit=15amp.

If I have a load of ~1400 W and my refrigerator starts, the load momentarily exceeds 15 amps and the “Power Assist” cuts in as it should. However, instead of AC1 supplying 15 amps and the balance coming from the battery, it splits the load approximately in half with ~ 750 W being drawn from the battery. This is a problem when the battery is in a low SOC because it drags the battery down when it should be charging. Also, even when the AC load reduces to below 15 amps, the “power assist” is still activated and stays activated –and taking power from the battery--until the load is significantly reduced to say ~300W.

Is there anything that can be done to correct this problem?

Hi George, I'm sorry you are having this issue. I recently purchased a brand-new Quattro 48/5000/120 and have been doing some bench testing prior to installing it into my new Outdoor RV. I am seeing exactly the same issue. Power assist is pulling from the battery even when the load is well below what the AC input can deliver. See pic. My Victron Distributor seems to think this is normal. I'm hoping someone in this community has some answers. This is not how the product is supposed to work. is this a bug or a feature? Yes, I did update the firmware to most recent version.
