      If 2s and 2s were wired in parallel but oriented differently with a 60 degree angle between them, they would never present more area to...

      That's what doesn't work well. The 1 panel will pull down voltage of 2 panels series. You'll end up with output similar to 2P. You will...

      Only to inquire. First, visit your utility (PG&E) website. Register an account and enter your system design, using their pull-down...

      Most decent MPPT, SCC or inverter, can handle PV capable of delivering excessive current. They will declare an Isc limit. That...

      Well, inverters record lifetime power production. Record lifetime PV MPPT harvesting, record lifetime export through CT to grid and make...

      OK, so just to comply with tariff requirement that battery doesn't get charged from the grid, then later discharged to grid? If only...

      I don't understand what the issue is regarding PCS. Was that to limit 18kpv to 16A backfeeding into 100A panel? Limit backfeed to grid...
    • Hedges
      You might do a line-side tap, 100A fused disconnect, feed 18kpv from that. If you can free up 2 slots in your panel by using tandem...

      A 320W panel is going to be at least "24V" nominal, 35Vmp, 40V or so open circuit. That shouldn't be used with PWM and 12V battery, need...

      I don't think heating elements have high TCR like an incandescent bulb (10x current when cold). Current draw the moment heating element...

      Hedges replied to the thread Inverter PV Size?.
      1) Main breaker + backfed PV breaker at other end of bus doesn't exceed 120% of busbar. 2) Main breaker + backfed PV breaker anywhere on...

      Hedges replied to the thread Inverter PV Size?.
      If you have lugs allowing 3x 200A panels and one is available, maybe 200A panel with 125A main and 100A backfed breaker. Or 225A, 125A...

      Installer, I think, and from there you can set user password as well.

      Four 175W panels is fairly small. Try to find wind speeds for your area, and an on-line calculator for forces. Bending moment will...

      I'm not personally familiar with it, but this indicates 28A at 240V...

      What we really want is frequency controlled continuously variable dump load. SMA used to offer Smart Load 6000, which did that...

      Hedges replied to the thread Off topic, EV vehicle opinions….
      How about a relay switching Leaf's connection between 120V and 240V? Two levels of charging, depending on SoC & inverter load.

      So a load kept it from getting knocked offline? Maybe altered SB settings will keep things on line without that. SI can enable a...
