Re: 1 of 8 RE16-B

Hi JR, I had a “1 of 8” L-16 REB issue with one cell going out after 6 years use. I replaced the one dead battery with 2 Trojan golf carts (in 2018). The overall battery bank has now had almost 8 years of use, so I have gone ahead and proactively ordered another 8 REB’s. They have been good to us. W...

Re: How true a sine wave?

Interesting. Have you used the same instrument to measure the sine wave from your local Grid? Perhaps that would be a quick & dirty way to informally "calibrate" your oscilloscope (if you still have it).

Has anyone else measured the sine wave from their outback inverters?

Re: Trojan battery morning reading

Hi, I also have Trojan L16's (REB's). They are coming up to 6.5 years. I get lots of sunshine apart from a few 3 day periods a year when it rains buckets, so charging is not as much of an issue. But, if you say "Trees shade my system most of the day this time of year" perhaps you can take a look at ...

Re: Is it wise to buy spare Outback 'parts' - just in case?

Update: Raysun and JP, My backup (GFX1448) Inverter was ordered from Outback. It was discontinued stock, so was on sale. I will keep it in dry storage for now after it gets shipped. I agree with you on my faith in outback gear, it's just hard to get stuff sent in time. So I think a back up is pruden...

Re: Flex Power 1 Db level and heat

Re: GFX Grid Tie Inverter - need batteries to be grid connec

OK, I may have an answer from the GFX operator manual. "The inverter requires batteries to operate. Other sources may not maintain DC voltages that are consistent enough for the inverter to operate reliably".

GFX Grid Tie Inverter - need batteries to be grid connected?

Quick noob question: do you need to have a battery bank for a GFX inverter? Ie can it be grid connected-only, supplying power from PV back to the grid? I am just curious and my 5 minute search did not produce an answer.
Cheers,

Re: Is it wise to buy spare Outback 'parts' - just in case?

Yes, I have heard before that the FP1 enclosure is a small and challenging space. Fortunately, my wife has very nimble fingers, a sharp mind, and loves that sort of thing. She is an assembly addict of sorts.
I am lucky.

Hi Raysun, Really good advice. I like the idea about the GFX (being discontinued so on sale now). In my case the GFX1448E would be the right unit for our specs, and I believe it should play fine with my Flexpower1 if we ever needed a replacement. We have an inverter fridge which draws, at most, 360 ...

Offgrid, Than you for the good grounding advice. I currently only have one ground rod (5" long embedded in wet clay soil) with all my grounds (panels, FP1, House AC ground) going to that single ground. After reflection, I think it's prudent for me to, first, enhance my grounding and surge protection...

Hi JT and Sodamo, Thanks for the feedback. Agreed, it's hard to predict which gear I may need(plus some of those boards are pretty expensive from the looks of it).

Thanks Sandy and JR, In answer: Yes I depend 100% on my system. In case the FM80 goes down I have a spare (Tristar45 PWM) Controller (I would have to reconfig my panels to strings of 2) and a Honda briefcase generator as backup. I would buy a new FM80 and fly it in personally in my hand luggage. It'...

Is it wise to buy spare Outback 'parts' - just in case?

So, I bought my Outback Flexpower 1 system (VFX3048, FM80, 230 v, 48v, Mate2) in part because I read that it was user field serviceable.

I own a hub and an FNDC. The latter has never once displayed correct SOC despite the resetting, etc, etc.

If anyone has an FNDC that even somewhat accurately records SOC -(SG verified)- please let it be known.

Re: Q for the Outback Tech's: FM80's Terminal AMP Ratings?

The FM manual says you should use copper wire rated at 75┬░C or higher. I think you can safely assume at least a 75┬░C rating for the FM80 terminals. ...but more likely 3 (60 cell) modules in series in order to get the proper input voltage to the controller (for a 48 volt battery the PV VMP should ...

The FM80's minimum voltage recording is not accurate, so should not be relied on.

Re: Any way to set a minimum Absorb Time on a FM80

A wee update: I've managed to raise Absorb times from an average of 30 minutes a day to around 2 hrs a day. As a result my end of day SG's have improved from an average of 1.245 (and dropping), to consistently about 1.260 /1.265. I still have to perform a lite EQ to get up to 100% SOC (1.275), but o...
