    Connector help!

    Uh, I'd rather not void my warranty by attempting to desolder, and solder in new electrical connectors on $11,000 on in brand new LiFePo4 batteries. Probably Lazer welded anyway. But of course making it submit to my 20th century wiring was my FIRST thought, briefly.

    Connector help!

    Yes, thanks, I've found half a dozen suppliers, but my problem is I don't know, and nobody can tell me what size they are... Maybe 10.3mm or 8mm. Usually with other connectors I would just buy them in all the different sizes and send back the ones that were the wrong ones. But in this case these...

    Connector help!

    Ok, I called customer service after pouring over every stitch of documentation from Aolithium where they specify the brass connectors on one end but make no mention of the other end - the end I need. They were clueless (and obviously not technical support) as to my question, much less the...

    Connector help!

    The EG4 only seems to be the load set with the SurLok connectors on only one end. Yes, I need those, but I need the short parallel cables with connectors on both ends too

    Connector help!

    I went into the hospital for an extended unplanned visit, and my system unattended, and unwatered boiled the battery "dry." I've got 3 nifty strings of 12v, or a 12 & 24, or 36v. Even setting my SI6048 for a dead cell, without physically being able to bypass it (#8) the inverter almost...

    Connector help!

    5.7, 8, & 10.3 appear to be the sizes the Amphenol SurLok plus connectors come in. Anybody have any idea what size and/or why not one battery vendor will tell me?

    It appears to be, yes

    Connector help!

    Maybe, I thought they were something like Amphenol SurLok, but I've no idea the size, and I'd prefer a premade cable.

    Connector help!

    Help, my vendor has left me in a lurch. My FLA bank failed a few weeks ago, and we've been alternating between dark, and running diesel generator. I took the plunge and ordered 6 - 51.2V 100Ah rack mount batteries from Aolithium - mostly because they could promise I'd have them by the 5th. My...

    SMA Sunny Island no longer agrees with charge controller(s)

    It figures it all those ways, yes it sees the Midnight Classic 250s as 2 SIC-40 charge controllers, AND the data from the Whizbang is used by the Classics... Usually this all agrees, they all agree on Ah in/Ah out. However the SI also monitors the battery voltage, and 46v triggered an SOC...

    SMA Sunny Island no longer agrees with charge controller(s)

    Oh, looking back through my charts I see what is happening. Even though the charge controllers, and my SI6048 agreed that the battery was at 88% SOC the SI 6048 suddenly dropped it's version of SOC to 20%, went into Battery Protection mode, and cranked the generator. The generator however is...

    SMA Sunny Island no longer agrees with charge controller(s)

    I'm showing 53.4 V with the generator disconnected from the system for about an hour now - I was literally boiling the battery. Last full charge 4 days ago, and 80% soc cutoff (rain/generator) since. Charge controller says it's full and in float. SI says 40% and it's mad that it can't get the...

    SMA Sunny Island no longer agrees with charge controller(s)

    Hi guys, my 5year old system seems out of whack. My networked to my SI Midnight classic charge controllers at this moment say I'm at 97% SOC, and they're putting a 'trickle' of 20A to the battery, BUT the SI6048 says it's 39% SOC and wants to run the generator and put 120A to the battery. Help...

    My WhizBang Jr, and my 500A/50mv shunt equipped SMA SI6048 badly disagree

    Yes, it is wired via MODBUS/Canbus comm adaptor to communicate directly between the 2 Classic 250s and the SI6048 and while the Classics themselves are wired to the shunt (via WhizBang Jr) the SI6048 is not, and takes its data from the Classic 250's which in turn are controlled by the SI6048. My...

    Over 5 inches of rain in 28 hours - worst solar day ever.

    My previous Onan diesels were 1800 RPM 4-pole units - a 10HDKAG, 7.5HDKAL, 7MDJE, and 12.5DJC - but they were also open frame units. My current ones are multi-pole permanent magnet inverter (and cycloconverter) units with RPM that varies with load and are completely enclosed along with the...

    Over 5 inches of rain in 28 hours - worst solar day ever.

    Yeah, just a little resentment after being forced to replace my generators with more modern units (see signature), and build a building around them for sound attenuation (at the cost of thousands of dollars) so that my generators are nearly whisper quiet - by the same people who forced the issue...

    Over 5 inches of rain in 28 hours - worst solar day ever.

    Over 5 inches of rain in 28 hours (nearly 6) below shows 24 hours of it and it rained over an additional inch since midnite. The neighborhood is a chorus of (cheap) generators - worst solar day ever 0.2KwH We're at the 42 parallel North - on a line with Cape Cod but as you can see our weather...

    Looking for input/advice for off-grid Cabin.

    Regarding tankless water heaters. I've had both the manual (3 knob) LPG on-demand water heater that uses a battery for ignition and the electronic (digital control) units that allow you to set an exact temp and leave it but they need 300W or so in operation (fans + electronics)... several of...

    Off-Grid From Scratch

    The original and only written reason was that after my house burnt down I lived in my RV that has sat here for 15+ years for more than 14 days. If I remove it ( it is on a foundation with no axels) then I can have power as soon as I have a permit to build a house, but as above they claim I'm in...

    Off-Grid From Scratch

    I always thought that was all there was to it, if power was available you could have it. After paying for the pole, all the associated wiring and cabling, inspections by the power company and an electrician, and the power company stringing line the county planning office when they came around do...

    Weird question about a weird smell

    I was going to say that maybe it had old film in it then I put on my glasses... dust.

    Liquid sunshine! Data collection...

    I pay most attention to the direction of flow (in/out) of the battery, the volume (A), and volume/time (Ah) count. Secondarily I pay attention to production (directly) from the PV, my battery temperature, and (calculated) SOC. Thirdly I pay attention to cumulative figures for Ah production from...

    Liquid sunshine! Data collection...

    I guess I didn't mean what data was available to you - I've got tons of data I don't care about that I can pull out of my SI I just don't unless something is really wrong. I guess I meant what data do you choose to record and look at on a regular basis. The above are the ones I follow the most...

    Inverter / washing machine issue

    My SI6048 Sunny Island doesn't even show that it notices the washer running, but none of my generators are exactly 'happy' with the pulsating load of my direct drive washer. It runs the washer just fine, but it makes the generator blow smoke rings and sound like a teenager in the driveway...

    Liquid sunshine! Data collection...

    Curious, how much data do most of you collect, and how? What a wet start to the new year - the Pineapple Express system. 3.5 inches of rain between Dec 28 and Jan 3! Solar production? Not much, but even on the wettest day there is something. Twin arrays of 3kw ea and a diesel inverter...

    Saskatchewan off grid questions

    I'm FAR south of that and MY 6000 watts of panels seldom makes more than 10KwH/D on our brightest sunniest December or January day.

    Saskatchewan off grid questions

    My generator is completely under the control of my SI6048 Inverter/Charger - somewhere around 3hrs a day this time of year, though the weekly full charge is 6+ hours, and my monthly equalization charge is near 10. If I had it all to do again the only thing I would change is where my panels are...

    Saskatchewan off grid questions

    Nowhere near as far north as you here at the 42nd parallel N. I've got 18 - 330W panels and a 6kw inverter with similar (15Kw/D) usage and this time of year the generator runs every day (I haven't seen the sun in a week), in the summer I still need the generator to provide scheduled 'full' and...

    That far north, unless you want to replace your batteries often a generator is a necessity.

    Remote starting with an existing load

    My SMA Sunny Island SI-6048 allows me to set the 'warm up' parameter for my generator which is currently set so that the generator starts, then runs for a minute at no load before the SI starts to ramp up the load. Also has a 'cool down' parameter too where it disconnects the power before it...
