Re: [RE-wrenches] OB Radian / FM60 grid tie mystery

One other thing that has worked for weird issues is a full factory reset of everything.  Jay On Aug 18, 2024, at 4:18 PM, Maverick Brown <maver...@mavericksolar.com> wrote:   On OpticsRE go to devices, Mate3S, Global Charge. Disable everything there and for good measure also set the Maximum Battery Charge to generously large number.  Also, if you recently upgraded to Inverter software 1.6.63 or later, you have to do some procedure to edit the maximum sell current <preview.png> upgrading_1_6_63_app_note PDF Document · 200 KB Thank you, Maverick Maverick Brown Off-Grid Solar Commander since 2006 Maverick Solar Enterprises, Inc.  • Solar Commander Remote Power  • SunFlow Systems Cathodic Protection  maver...@mavericksolar.com 512-460-9825 On Aug 18, 2024, at 3:59 PM, Kirk Herander via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote:  Looks like its only programmable directly on the Mate3s, not in optics RE.

It sold back quite normally until the last several months -3.- FM60 CC's are set to grid tie mode and  viewable and programmed from the Mate3s / OpticsRE. This issue loosely correlates to replacing one of the CCs several months ago. Trouble is all -3- charge controllers are almost always in a float mode. The radian does sell, but at a small KW compared to what it used to before the frequent float mode started popping up. If I remember correctly, ideally the CCs should always be in bulk charge when sellback occurs. I have the CC and inverter charger float set to about 1 vdc higher then the inverter's sell volts, as I believe was recommended way back when. Hard to understand what changed, but something did. I've checked the relevant setpoints many times and can't find anything obviously amiss. Does a sell mode tech note paper exist still for the Radian system? Did it ever? Any ideas would be greatly appreciated. -- Kirk Herander / kirkh@vermont.solar Owner|Principal, VT Solar, LLC Celebrating our 33st Anniversary 1991-2024!! dba Vermont Solar Engineering 802.559.1225 _______________________________________________ List sponsored by Redwood Alliance Pay optional member dues here: http://re-wrenches.org List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org There are two list archives for searching.
