    120v...important detail!
  • Post in thread: What were your costs for the "little" things?

    The panels, inverter/charger, and battery make up the majority of the expenses. Obviously the exact configuration (i.e. lengths of wiring, etc) will be different for everybody. But roughly - what were your costs for all the little things and with what # of panels? Wiring, terminals, mounting...
  • Post in thread: Is there a secret to the MC4 connector screw cap?

    It does look snug around the cable with the cap removed. It looked like the panel wire was pretty similar in size. It's all in the correct housings, I had it hooked up and powered up. I'll check with SS to see the intended wire size spec, there are no model #s on these connectors.
  • Post in thread: Panel wiring length differences

    So battery wiring needs to be the same length, I got that. If I wanted to space out some solar panels - physical location maybe 50 feet apart, but with different wiring paths into the house where they would eventually meet. The wire lengths would obviously be different by dozens of feet, would...
  • Post in thread: Is there a secret to the MC4 connector screw cap?

    It's going on like this. (this pic is just an example, it's not crimped and installed) When I hand tighten to max, the cable won't move anywhere there is enough force on the grommet. But that's with the cap halfway on.
  • Post in thread: Is there a secret to the MC4 connector screw cap?

    Yep it definitely clicked!
  • Post in thread: Is there a secret to the MC4 connector screw cap?

    Hand tightening without a cable inserted really closes the grommet. I really wonder if these are for smaller gauge wires. Will see what SS says tomorrow regarding model # / specs.
  • Post in thread: Can I get a spot check on my first solar build.

    Meant to be for emergency power and also run a few small things to reduce my electricity bill. It's a temporary solution until I can put a full solar system on my roof. Might add an AC to DC charger later but for now, don't really want to expand beyond a bare minimum (which is very tempting!).
  • Post in thread: Can I get a spot check on my first solar build.

    I do have a generator for larger power draws. However my mini split pulls 550-650 watts and this inverter can peak up to 2200. Unfortunately to scale up at 48v gets expensive quick beyond this inverter.
  • Post in thread: Is there a Victron MPPT -> EG4 Battery guide/tech doc?

    I'm considering pairing a Victron Smartsolar MPPT with an EG4 LifePower4 Rack. I've been reading about the different BMS and communication systems from each manufacturer but nothing that really talks about connecting the two together and guiding through that process. It's not just plug them...

    Pioneer 9k. https://www.pioneerminisplit.com/products/9-000-btu-ductless-dc-inverter-mini-split-air-conditioner-heat-pump-115-vac Spec sheet says AC pulls 720 watts at 115v, my breaker meter (Vue 2) shows 550 watts on normal mode, 650 watts on turbo. I think the inverter 2200 peak should cover...
  • Post in thread: Running solar panel wiring next to 120v

    I'm planning an "off-grid" setup for a mini-split AC running off most likely EG4 system/battery and 4 solar panels. The AC compressor and 4 panels will be near each other in my backyard with the EG4 in my garage. I will need to run both the 120v line and the solar panel feed through the side of...
  • Post in thread: Can I get a spot check on my first solar build.

    The inverter can be configured to neutral floating or neutral connected to earth. Since this is an isolated "grid", from reading Victron's wiring document, I believe it should be neutral connected to earth which is the system grounding wire connecting to a rod in the ground. Not to be confused...
  • Post in thread: Can I get a spot check on my first solar build.

    Gotcha. But this is off-grid, I am not connecting it to my existing electrical system. I am going to wire my mini split and anything else directly to the inverter (via breaker).
  • Post in thread: Is there a Victron MPPT -> EG4 Battery guide/tech doc?

    Yeah just charging is all I really need - it's an entry level system for backup. I'll have an inverter (Victron Phoenix) for battery output. I'll use the MPPT bluetooth for monitoring. I guess I was confused why the EG4 LL mentions Victron communications and invertersrus mentions programming...
  • Post in thread: Running solar panel wiring next to 120v

    Thanks for the info! Haven't made it to the electric run planning yet but good to know about the metal conduit. I've seen the arc fault devices, is it going on the solar wiring or the batteries? I see pics of it on the battery wiring side of the EG4.
  • Post in thread: What is the most entry level 48v inverter/charger?

    I'm planning on putting solar on my roof but I have to wait on a few other things first. I'd really like to get a couple panels that I can pair with a 5kw 48v battery (such as the Eg4 rack) in case of a hurricane or other extended power outages. I have a 12v inverter but I don't want to invest...
  • Post in thread: Can I get a spot check on my first solar build.

    It took a bit of research but I did find Westinghouse DIN breakers. Spent my morning researching that, MC4 connectors, wire, etc. Too much junk out there to avoid!
  • Post in thread: Is there a secret to the MC4 connector screw cap?

    I just cannot get the end cap screwed on even with pliers. It will start by hand but then tighten up and go no further. These are name brand Stäubli from Signature Solar and TEMCo 10 gauge solar panel wire. I bought name brand quality to avoid issues like this! I did exactly what all the youtube...
