    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)

    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...

    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...

    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...

    Lion Energy UT1300 at Costco again, why buy them?

    I know you guys keep telling me that LiFEPo4 is at price parity with my dinosaur of a lead-acid battery, but even if you adjust for the difference between 80% DOD and 100% DOD and replace my 986Ah 48V battery with 700-800Ah of these I don't see it - you are still talking $22,400 + tax vs $4995...

    My diesel generator's cost of power produced.

    Well, 'Eloise' our Cummins Onan Quiet Diesel QD8000 (8HDKAK) numbers are in for her first tank of fuel. And show her to be a couple of cents more per hour than my highly modified 10HDKAG Onan 'Ellen' that preceded her, though about 20% cheaper than the stock unmodified 10HDKAG. In the last 98...

    Brrr, my battery is cold.

    Thanks to a changing climate instead of being rainy and 40-50 degrees, we've been sunny with lows touching freezing every night. I insulated the battery case with 2" foam, but we're still struggling to stay over 60 degrees, every night is a few more degrees lost, we're at 59.9 and dropping. I...

    Help, need ideas quick!

    Thanks to two companies that made equipment that was supposed to work together each thinking the other had told me of necessary settings not found in the documentation from either, a $4000 inverter/charger is being replaced 14 months into its 10-year warranty. The new one is here but that is...

    What do you call these?

    I'm trying to find solar connectors that pass thru the walls of a box - like these in the photo. I can't come up with the right name to find them to buy them. What do you call them? Thanks,

    MidNite Solar?

    I lament having spent a year's worth of my disability on all this MidNite Solar stuff I have. After the incident where at the close of business on a Friday they told me that my broken MidNite Classic 250 that had been in service for 9 months, was actually 9 years old and out of warranty - that I...

    SMA KTY Battery Temperature Sensor replacement options

    Hi, last night my SI6048 shut down abruptly with W212 (high battery temperature warning) F206 (battery over-temperature) warnings - restarted it and it did it again (x3). Finally, after using an IR thermometer to make sure my battery wasn't really hot (72.4 degrees F) I disconnected the battery...

    How do you get ash from the fires off your solar panels?

    We had a few days where ash from the wildfires came down like snow, now how do I remove it from my solar panels? I've tried blowing it with a leaf blower. Sweeping it with a broom. Squeegeeing it with a squeegee and water. Rinsing with low-pressure water Rinsing with high-pressure water (hose...

    Industrial/Forklift batteries - what is in a name?

    I had some blood flow to my brain today (LOL) so I thought I'd share what I'm remembering while I remember it. If this is old news to everybody, or I wrote something just like this before, please disregard it. Industrial batteries will often be named as the one in my profile pic 24-125-11...

    Shortest wire path for three sets of three panels

    Where can I go?

    Hi, Can anyone point me toward a forum were people might know SMA? All my attempts here and most others elicit only the sound of crickets. Perhaps there is a SMA forum I just can't find, or some other forum where SMA is more common? I search here and I only get a handful of threads, half of...

    Any SMA gurus?

    Hi guys, my SI6048's SOC calculations are all over the place. Case in point: Yesterday my SOC was at 82% (WBJR said 100%) and I withdrew 166AH (net) during the day. This brought my SOC down to 45% (WBJR said 62%). The generator cranked up and as soon as the SI6048 started charging it showed a...

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

    The SOC figures vary greatly occasionally requiring my intervention to keep from badly overcharging my battery. The SI6048 supposedly receives data gleaned from my WhizBang Jr via one of my 2-networked Classic 250 charge controllers via my MODBUS/Canbus adaptor. The WhizBang Jr (and...
