  • Electrician being born

  • Things you'll want to know starting out.

    Hi there! I assume you're wanting to get into solar power, battery storage, inverters, micro-inverters or some mixture of the aforementioned. If not, you're definitely in the wrong forum. If you have a good understanding of electricity and how power flows, you've got a good start. If you have no...
  • When Mario puts his work in your way

  • Finally done (*for now) with my battery rack.

    Only thing I want to do at this point is fuse each battery, but need to regenerate some funds as fuse blocks and fuses are 'spensive. (Also potentially get 3-6 more batteries later) 6x EG4 Lifepower4 EG4 Rack Communication Hub Blue Sea Class T fuse holder and fuse Blue Sea Switch (Mistakenly...
  • Thoughts for EG4

    Looking through your Downloads page, there's no apparent way to tell the version / revision date of anything there without downloading it (To get the version, no dates are mentioned) In fact, looking through your entire website, there's no way to tell when new firmware gets released for any of...
  • Micro air easy start 368-X72 $275 (Austin, TX)

    Unit is 5 months old, replaced entire air conditioning system with an inverter system, no longer need soft start. Also no longer need the nest device, but probably no market for those.
  • LifePower4 Battery SOC%

    I've noticed that battery 6 seems to always lag in SOC%, but the voltages across all 6 batteries is balanced. When CHMOS turns off for all batteries, Battery 6 rests at 90-92%. Positive feeds the busbar at the top with the fuse, Negative feeds the busbar at the bottom. Is this something to worry...
  • Code required labeling

    Where does one acquire labeling required by article 692 in us 2023 electrical code?
  • Communications between Sol-Ark 15k and EG4 Communications Panel

    Just prefacing this with: I searched extensively for the answers I needed, but couldn't find them due to weak google-fu, or it just not being available information. I have a newly installed Sol-Ark 15K on my house that was converted from an Enphase microinverter system as Enphase is super proud...
  • Heat on terminals.

    When my system was under an extended 150a load, I went to check on wiring for warmth. The negative busbar connection was room ambient temperature, but the connection at the fuse and the fuse itself was warm. I say connection, but thermals indicate the crimps are potentially not solid. However...
  • Adding a circuit to an in-wall panel.

    I have a panel in my garage wall and I want to add 2 circuits to my garage. I was planning on running EMT near the ceiling and then down to where the refrigerators will plug into them. My question is: How would I go from the panel in the wall to EMT out of the wall? 90? Offset? The electricians...
  • What to do when you have more solar than your inverter can handle?

    Not in this situation yet, just planning on adding more solar and that would put me over the limits of the solark 15k. Do I start doing complex arrays of s/p to keep under the max voltage allowance? Currently at 9.2k with 35x TSM-290DD05A.05 (290w 39.5voc) in 12x12x11 into the Solark 15k.
  • New, more efficient solar panels coming? Hopefully.

    They seem to think it will be much cheaper to produce than current panels, too. https://www.nature.com/articles/s41467-024-46620-1 https://en.shiftdelete.net/solar-panels-becoming-obsolete-a-70-cheaper-alternative-is-coming/
  • Solark Notification

    Do we need to register on mysolark.com or wait for all the migration to conclude? Wording seems to indicate wait, but want to ensure I don't mess anything up or lose any data.
