<div><span><font color="#0000ff" face="Arial">Yes, it's pretty nasty. This is why we stopped using Outback products for off-grid sites with significant use of generator charging. Not only are the chargers really wimpy, we found all manner of harmonics caused by the charger circuit. Loads ran fine on inverter; fine on generator but would not run at all or reliably with gen running in charge mode. </font></span></div>

<div><span><font color="#0000ff" face="Arial"></font></span> </div> <div><span><font color="#0000ff" face="Arial">What we have done successfully for sites where the customer doesn't want to replace the Outback is install a bank of external battery chargers, ie the Iota DLS series and use those for gen charging purposes only. Sub-optimal in a lot of respects but that's what happens when a client buys hardware and says "make it all work". A DC genset would be way more efficient. </font></span></div>

<div>Roger the 136-272 charge amps, and the theoretical max of 295 with this system. Hoping for reality of 160 - 200. Fortunately it's a 'good' customer with very efficient running loads, just a bit of a power tool habit and the hydronic heating recirc pump loads. Unfortunately, there have been 3 trades on site recently using power while I'm trying to get the battery filled up! but generally about 3x solar/useage during fair weather.</div>
<div>With 3 inverters, this week I'm trying #3 with full charging, 1 and 2 at about 60%. #1 should carry most of the load demands, #3 most of the charge demand. I also found a spot in the Mate 3 to set maximum charging kw and I set that to 7kw. Maybe that will help gen overload.</div>
<div>Has anybody scoped ac line to VFX's under full charge load? I'm curious about harmonics possibly being the culprit between a 12.3 kw load bank not tripping the breaker, and a 5-6 kw charging load tripping the breaker...<br>
