    Check scc with power supply possible

    Ok, OK mega mea culpa. I did have the SCC connected backwards. I checked at the panel but at the SCC which i had wrong. Everything works now I'm sorry for wasting everybody's time. But I thought I would post some pictures of my project as it may make you smile.

    Pi, thanks so much for your help Battery 26.33 Solar 0, always 0 even at noon Absorption. 28.8 Float. 27.6 Mattb4 I am getting 45.6 volts at 6pm. Would have been higher I guess at noon

    Yes. The polarity is correct. I double checked it before connecting.

    Check scc with power supply possible

    Thanks, The battery is 80% full so there is room to charge. And the SCC is enabled. I think the problem must be with the panels or the SCC. I am just trying to determine which. Is connecting a dc power supply to the SCC a good test, or will it be a problem?

    Check scc with power supply possible

    I have a victron 15/75 scc connected to my 24v battery and two renogy 175 flexible panels connected in series. The victron powers up due to the battery power but does not charge the battery even though the panels are unobstructed and it is a nice sunny day. I'm not sure if the problem is with...

    Sol-ark 12k canbus necessary?

    According to Sol-Ark the way it is supposed to work is that the bms sends signals via canbus sa the battery nears the top and this causes the solark to reduce the charging level until eventually it is zero. But solark already knows the pack voltage and has a maximum voltage setting for the...

    Oops. I made a mistake. Not SOC but pack voltage level.

    Sol-ark 12k canbus necessary?

    I have a Sol-Ark 12k and a DIY 48v 280AH battery with an overkill bms. Overkill does not have a canbus port. Is canbus really necessary. Won't the solark control charge/discharge via SOC

    Will hot water on snow covered panels cause thermal shock?

    OK, the final tally is: DON'T DO It !!!: 14 Should not be a problem: 2 Do it and let me know what happens: 1 Use your shotgun: 1 Since my motto is: "It's better to ask stupid questions than it is to do stupid things" I think that I will refrain. Thanks for the help.

    Will hot water on snow covered panels cause thermal shock?

    Ok, so it is my first winter with my solar panels and as expected they are now covered in snow. I have the ability to redirect water from my hot water heater to an outside hose bib. Should I just hose them down with hot water, or is this going to break the panels?

    Blue Sea Fuse Block: 32VDC really?

    Great response. And the video gives me an idea. I think I will blow a few 3 amp fuses, some at 32 volts and some at 60 volts to see if there is any difference.

    Blue Sea Fuse Block: 32VDC really?

    I bought a Blue Sea fuse block for my 16s 280AH battery build. It is the one with 12 terminals, 30 amps per terminal 100 amps per block. Its purpose is to provide protection for low power items like the alarm horn, bms, pack voltage sensor/relay etc. But i see on the specs on the back of the...

    adding a small kicker cell to a 16s battery? 16s+1

    good point. But if I started out with the compound cell at 20% and the others at 10% I guessing that I would not have any problems.
