Mix up in the warehouse and the incorrect accessory kit was dispatched... Fogstar taking care of things.

Go to nkon in .NL, they'll help you out. Failing that, shipment from the UK to Europe is a piece of piss, I do it everyday. Go to Fogstar, they'll definitely take care of you.

Highly recommend the carlingswitch brand dc breakers available from outback and midnite solar. They are dc rated, none of this chint rubbish. Midnite make a decent array of ‘balance of system’ components, breaker boxes, combiners etc. Well worth a look. The Gudgel brothers have been doing this...

Ok, I get it now. User defined won’t work without incoming can messages, and lead acid isn’t user-adjustable… Sounds like a shit inverter ? You need to get your absorption setpoint changed, one way or another.

Orion is not batrium….. Orion good, batrium bad

People try, but unless your cells are perfect (easier to do now that we have access to such good quality prismatics), you’ll be forever fighting runners, at least in my experience. Hardly worth going for that last 10 % and stressing about everything shooting up the upper knee, much easier to...

New bms from fogstar and we’re up and running…. Now to find my eltek flatpack and get this thing charged up.

55.2 - always 55.2 for lfp, none of this 58.4/3.65 rubbish…

This is what I’ve got. Works a treat over here in mm2 land. I prefer it to my ebay special hydraulic one, mainly because it doesn’t leave wings.

I have heavily abused my CALB plastic cased lfp cells, charging them when frozen, discharging them well below cut-off, charging them to 4v on occasion. They puffed up and failed, but they did not catch fire on me.

Into a failed pack….. parallel packs always need inter-pack fusing, with stuff that won’t catch fire. We were discusssing this 15+yrs ago on the outback power forum when I was messing with wet Nicad…

JK is fully programmable to open/close on any user selectable parameter. If I can’t get the bms to do it then I’ll use a cerbo gx, or build something from a canbus shield and an arduino.

In my opinion, yes….

Generic Asian R290 unit this end.... Seems to do the job.

Good to see you still keeping busy Bob…. Just retired my vfx3048e on fw500 hardware that’s been running continuously since 2007 - only retired it because the building it was located in needed to be demolished and it won’t fit on the wall in the house…

Flexnet + LFP owner here…. The flexnet is a shunt and %SOC tracker, with an aux relay. Nothing more. Bulk current/absorption setpoint + timer/ float setpoint are all set either in the outback inverter, the mppt, or both.

Why is your inverter set to 58.4v when you need to charge to 55.2? Inverter settings should be 55.2, absorption timer of 30 mins or so (for now), float of 53.8 (that’s what I’ve used for 6 yrs, works well at letting the cells rest whilst the sun carries the loads)

You told us somewhere up there ^^^ that the only one that was user adjustable was the ‘user defined’ charging profile. I’m not in front of your inverter, you are. I’ve told you the voltages to use, crack on and have a go at adjusting them.

I’ve got waste matters coming down sometime this year to deal with some chemicals off this site so I might just make it their problem. I’ve also got the wet Nicad recyclers coming down, they might also be interested in taking them on, I’m paying enough to have the 4.5 tons of nicads recycled...

What cells did build it with? I’m considering adding another one to my setup…

Agreed, it’s the same over in mm2 land, the dies are always mis-marked. These things take a modicum of intellect to figure out, and if you lack the ability to see that then you probably shouldn’t play around with solar and ess stuff. I’ve since switched to a mechanical dimple indent crimper, it...

Here’s the issue…. The Sunsynk called for generator start 6.1hrs ago (I have it on manual at the moment, don’t have the 2-wire start hooked up), I started the genset manually when I got home just now, transfer switch has moved the loads over, yet the battery isn’t requesting a charge….

Then what's the issue?

Yes, you can assemble it vertically… Fuse cover doesn’t fit because the busbar is wider than the slot in the cover , a minor issue. Blew the bms up due to a wiring mistake on my part… now to decide whether to swap batrium in, or buy another seplos v3…

Something else worth mentioning in case someone comes to this in the future, if you manually start the genset and want to charge, it won't switch over the transfer switch and start charging unless you %SOC is below the level that you set 'Gen load ON batt %' to. This is unexpected behaviour...

Correct. The Flexnet does not override the voltage setpoints programmed into the mppt and inverter. The original outback gear was designed before we had lithium storage, so the charge algorithms are geared for lead acid. They’re fully programmable, but the system has no ability to communicate...

No, I stand by my assertion that these are crap…. It’s an infinitely inferior product to the Outback, especially when it comes to surge rating…. Anyway, I’ll see if I can figure this out. My TOU settings are set to accept the generator input and to charge to 100% during normal non-quiet-time hours.

That’s water damage…. I fix flooded pcbs for a living, I recognise that a mile off.

I'm moving mine into the house, so heating wasn’t a concern for me. Current pack lives in an outdoor shed and hasn’t liked the cold over the last 6yrs. Think I’ve killed a cell or two from letting them freeze. Still unsure if I’ll buy a new inverter/charger or stick with the old vfx3048…

Yep, these come with the active balancer already installed. And most of the kit was pre-assembled. Wheels on, bms installed, cell collection pcbs installed.
