If it turns out to be true, could you simply add the Outback PSX-240 to balance the loads?

As little as 1400 watts? I could see where these instances would be minimized with attention to detail on balancing all the loads but if’s as little as a delta of 1400 watts that might occur with something as innocent as a toaster oven. Seems like it would also be less of an issue in a grid back up or AC coupled scenario but for off grid I’d be bummed to be getting calls every couple weeks from an off grid client that trusted me to offer the right equipment. How much of an issue is this? Is it getting exaggerated? Those that have NOT had this happening was it on a full time off grid site? Has it happened less on sites using the "Limited to Home” mode? I have an upcoming project that was going to be setup with a couple Radians in HBX mode and my thought was perhaps it might be an ideal solution there but if the continuity of electrical service was going to be provided mainly through batteries and inverting and not through the pass through relays the majority of the time then the site might likely experience this issue with imbalance shutdowns. There are many attractive features of the SolArk and I really like the thought of taking advantage of the 185 amp DC charger versus the Radian’s 115 but I’m kind of thinking the risks may outweigh the benefits if these shutdowns occur even once every couple of months. Any of you have a long enough history with them to chime in with your observations? Are they most reliable for AC coupled with backup rather than off grid or the “Limited to Home” mode? Thanks for your time, Nick A Lucchese
