<div dir="auto">Maybe its just me but if an off grid inverter can't start up a 120 vac compressor l might want to look elsewhere. I have the old FX inverters start up and run massive bandsaw while homes were being built. Radians running everything from well pumps to sewer pumps all while off grid all without additional transformers or soft start controllers. I have systems in Honolulu that have 5 AC multi ton units all living just fine with two Radians and no additional transformers. Its just a little concerning that load imbalance was not considered with this inverter manufacture, and maybe they did.

It\u2019s a new off-grid house build, and so not many loads to speak of yet, except mainly power tools. The Solark 12K will not start any of: portable air compressor, table saw, and sometimes struggles with a miter saw, which are each 16amps or less at 120V, but I have measured close to 50amps start up for the air compressor and table saw. The air compressor and table saw are 1.5HP each. What helps is if the motors are warmed up, or putting another load on the other leg to balance the inverter\u2019s output. <div><br></div><div>Was thinking we would install a couple of dedicated 120V outlets for \u201chigh-current\u201d 120V loads with a PSX-240, stepping down the inverter's 240 to 120. My understanding is this will solve the issue for starting these loads, but not sure if we might run into issues with inbalance down the road... Would be curious to know if there\u2019s another way to balance all of the house loads using the PSX-240?..<br><div>

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\u2019s 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\u2019d be bummed to be getting calls every couple weeks from an off grid client that trusted me to offer the right equipment.<br><br>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?<br><br>Has it happened less on sites using the "Limited to Home\u201d 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.<br><br>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\u2019s 115 but I\u2019m 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 \u201cLimited to Home\u201d mode?<br><br>Thanks for your time, <br>Nick A Lucchese<br><br></div></div></div></div>_______________________________________________<br>List sponsored by Redwood Alliance<br><br>List Address: <a href="mailto:RE-wrenches@lists.re-wrenches.org" target="_blank" rel="noreferrer">RE-wrenches@lists.re-wrenches.org</a><br><br>Change listserver email address & settings:<br><a href="http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org" target="_blank" rel="noreferrer">http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org</a><br><br>There are two list archives for searching.
