Re: MATE3s and daylight savings

Thanks Greg, I just checked those settings and I should be all set. I probably also need to bump my afternoon switch from Grid-Tie to Backup to a later time--days are getting longer fast! It's been kind of overcast so far this month but I'm hoping for some clear weather in the second half of March--...

Re: MATE3s and daylight savings

Thanks. I just checked the date and time settings and it said it was using internet time. I'll check it out tomorrow and see. If it were up to me there wouldn't be any Daylight Savings Time--just throws everybody out of whack twice a year (and around here it's practically dark when the kids get home...

MATE3s and daylight savings

Is the MATE3s smart enough to adjust to daylight savings time?

I have flextime set up to switch between grid-tie and backup, just wondering if I need to adjust that. I guess I'll find out soon enough tomorrow morning!

Re: Auto ReStart

Thanks for the explanation--since things seem to be working fine with my controllers, I was really just curious about the why. Maybe I'll play around with it at some point to a get a feel for what situations it can help in. Once the trees leaf out in May, I'll be looking at more serious morning shad...

Re: My Outback system @ 2 years of age

I'll try to taje and post some pix. Perhaps after I do a six-panel upgrade in the next couple of weeks. You're expected to accomplish that in 8 hours, OK?

I also called Outback (and Schneider) before committing to a gear purchase, and was reassured. For the most part my interaction with tech. suppo...

Re: dialing in the sell voltage

Thanks, I was just 2 weeks into using the system when I last posted, since then I've got it dialed in perfectly and couldn't be happier. I make little adjustments to the sell voltage sometimes if I want to nail the proper temp. compensated float voltage precisely while selling, but other wise it pre...

Auto ReStart

I've left my FM80s on Auto Restart mode 0, and everything is working just fine. But for my own knowledge and understanding, under what conditions would you want to use modes 1 or 2? Are there certain situations where this would be advantageous? Just curious--I like to know the "why" behind all the o...

I take it "from battery" kWh exceeds the inverter's output kWh because of inefficiency in the inverting process?

Re: At the studs, what would you do?

"Megunticook was saying they had fuses on their battery connection - I wasn't quite sure why except maybe charging spikes?" The old-school protection method is a big thermal fuse between battery and inverter input. You'll see systems wired this way, but breakers are more effective. In any event, th...

Those box dimensions you wanted (interior): 56" long x 19" wide x 23" high. Before you cut the hole for the battery cables to exit, be sure you know exactly where those + and - battery terminals are positioned and oriented, as routing 2 pairs of 00 cable in a tight space without straining the cable ...

Re: Placement/location of the FlexPower Board

I'll have to double check the battery box dimensions--it houses 8 Rolls-Surette S-550 flooded batteries, 428AH, and I made sure to have a couple inches of clearance around them for air circulation, plus a good 6 inches clearance above. Next time I go in there (probably later tonight) I'll take measu...

I talked with Outback and several battery manufacturers to make sure it was OK first, but I ended up putting my FlexPower and battery bank in an unheated shed outbuilding: So far so good--used a 12v fan in the exhaust stack for battery box ventilation, runs off the inverter's Auxiliary power when th...

Re: Understanding power flows in OpticsRE

However, the confusion for me still lies in how "to grid" and "From grid" are related. So in Optics "To Grid" is measuring power flowing from the inverter out to your main service panel. This only happens after any critical/backup panel load demands are being fully met by the inverter and the exces...

Re: Understanding power flows in OpticsRE

I disagree, about all we can say about that 0.7kwh "to grid" is that it represents current flow back toward the grid. And the 4.0kwh "from grid" is current flow into my inverter from the grid. So (it seems to me, anyway) the net to my inverters is the difference between the two. By definition the "...

Re: Understanding power flows in OpticsRE

Looking at your equation toward the bottom of your post, I don't think you want to subtract kWh sold to grid from kWh bought from grid. In other words, at that point in the day your loads have consumed 7.3 kWh. 4 kWh of that came from the power you bought from the grid. 2.3 kWh came from the battery...

Re: FM80 goes silent; MX60 still charging

My FM80s show the temp. comp. voltage that the controller is targeting. Regarding gtarolli's point, Outback's recommendations and my experience is that if the sell voltage is at least 1v below the controller's target, you pull down maximum current from the array. If the gap is any closer, the curren...

At the actual controller, enter the MISC menu, hit next, hit next again, and you'll see it second from right on the top. I use this a lot, very helpful.

Re: FM80 goes silent; MX60 still charging

I believe if you look at the Event History in OpticsRE when my CC displays read "GT Mode," Optics RE displays the charger state as "Float Charging." But it really is more like "MPPT Bulk" in the sense that the controllers are pulling as much current as they possibly can from the array and sending it...

Re: FM80 goes silent; MX60 still charging

Interesting--my controllers display "GT Mode" when selling. Essentially I think it basically means they're operating in MPPT bulk mode, though--when I check their target voltage when they're in GT Mode, it's always the absorption voltage setting (temperature compensated of course). My sell voltage i...

Re: FM80 goes silent; MX60 still charging

Sounds like you have this resolved but just in case it crops up again I'll add my two cents. I've had a similar issue with my pair of FM80s. In my case the fix was lowering the sell voltage a bit (I had it raised a tad for cold temps. since my battery bank is in an unheated space)--it seems that onc...

Interesting, you can sell 5x the power I can. That would be one hell of an array for a single residence, though. But it sounds like there's no point in producing more than you consume. Here if you have a power surplus you're allowed to allocate credits to multiple accounts, IF all the accounts are o...
