  • Post in thread: Interesting poll results! Sol Ark VS Signature Solar

    Hey, Shout out to Sol-Ark, Here in Alaska I purchased a Sol Ark inverter from a local installer. Price was good or about average for the lower 48 prices. Installer did a good job getting it put together with PV on my roof, main panel and safety switches. I am currently just waiting on a grid...
  • Post in thread: Poll: How was your experience with signature solar?

    I live in Alaska. Getting stuff here is almost impossible. Signature Solar did a great job. Got panels, mounts and a few other items. Way cheaper than my local sources even with the high cost of shipping. Everything arrived intact minus one damaged solar panel. Not on them, shipping issue...
  • Post in thread: Sol Arc 15K Can the generator port be turned off and locked in the off position?

    According to my installer and Poco the Sol Ark can and will be used in grid tie only. Sol Ark engineers actually has a zoom meeting to go over the specs, set up and programming with my electric company and installer. I was impressed at how good, professional and available Sol Ark support was...
  • Post in thread: Trench and conduit advice

    Frost heaves in Alaska are wild. Talking more than 6 inches in some places and at some depths. Can easily break a conduit in two and cause damage to wires. Deeper is better. PVC can get brittle up here in the well below zero temps so going below the frost line is important and safe. There...
  • Post in thread: High voltage vs low voltage solar panels for Off grid.

    Hey everyone, I just recently had a system installed. While I did not look at anything as high has >100 VOC or even over 60 VOC some were close to 50 VOC and when you factor in cold temps during winter you will easily exceed 50 VOC per panel. My main concern was the size of the panel. Some...
  • Post in thread: SolArk15k vs Eg4 18k

    Hey Shadowmaker, My home is pretty efficient in regards to heating. I have a 5 star energy rating and would say I pay less for heating per sqft than about 98% of the people in my city. I have a condensing boiler, tons of zones, all radiant and all digital controls...
  • Post in thread: Solar Shed Ideas?

    Hello JBoffgrid2022, I have a solar shed, 10 by 20 feet and muni approved. I did have to ground the shed x 3 and have DC shut off at the shed and back at the house, (inverter). I used super strut and bonded them to the copper grounding rods. I also ran 10g copper wiring underground back to...
  • Post in thread: You won't believe how much power it takes to do laundry

    Heat pump dryers, I have been trying to compare them to gas dryers. Efficiency and cost per load are very different. If you are going pure electric then a heat pump dryer is the way to go. Skip the standard electric dryer if at all possible If you have a gas line in place, and access to...
  • Post in thread: Trench and conduit advice

    I just ran a bunch of trenches. My local Home Depot rents a trencher for 69 USD for 4 hours. I used EMT pipe. 3/4 inch and ran four 10 gauge copper wires through them using a wire snake every 10 to 20 feet before compression coupling for a water tight seal. Use lube to help guide the wires...
  • Post in thread: You won't believe how much power it takes to do laundry

    Hey, At our place in Mexico we installed an indoor drying line. looks nice to me. Placed by a windows it works well for towels. Electricity in Mexico is expensive. Here is a picture of it. Bought it on Amazon. Green and saves money. Super low costs and not bad looking. For an off grid...
  • Post in thread: Need help mounting a few panels on small shed

    I would consider using super strut. Most solar panels can be fitted with a strut nut then mounted to super strut rails on a structure. You can bond them to the super strut and ground them with simple copper grounding rods and wiring. They make mounts for both metal and asphalt shingle roofs...
  • Post in thread: SolArk15k vs Eg4 18k

    Hey everyone, Okay the spec sheet on my Sol Ark 15K is rated down to -40C confirmed. This is important for me as I am in Alaska. My main panel and meter are near (just on the outside for meter) and inside my mechanical room (my main fuse box). My house is serviced with radiant heat via a gas...
  • Post in thread: SolArk15k vs Eg4 18k

    No batteries as of yet. Grid tie application in process. If I did get batteries would put them in my mechanical room, wall mounted up high or in my garage would be an option. Garage would be a long run with expensive cables so my least favorite option.
  • Post in thread: SolArk15k vs Eg4 18k

    Brucey, Not likely to be covered but access in the winter will be difficult. Over hang above, but 3 stories above. The first 2 feet around my foundation are without snow commonly do to radiant heat in the concrete slab. The meter is also low but higher than the Sol Ark. The exhaust from my...
  • Post in thread: Trench and conduit advice

    Wow, not a lot of love to EMT. While not always the best option please keep in mind every situation is different. EMT that is zinc coated galvanized steel should make it about 50 to 75 years. All connections must be sealed if underground. Probably a longer life than the shed it is running...
  • Post in thread: Trench and conduit advice

    I am sure PVC would have collapsed just as easily as the EMT though not due to rust. Newer EMT that is zinc coated should last a while. Some good news, 6 to 8 months of the year there is no water or wet as everything is frozen where I am at. Then the thaw comes so a month of constant wet...
  • Post in thread: Sol Arc 15K Can the generator port be turned off and locked in the off position?

    Agree fully. I am set up to control what I use and what I sell back via the Sol Ark. The fee is kind of a processing fee I guess. Goal is use first always. Batteries may make some sense but the fee is really small when net metering so not sure if I will ever do that. I like keeping it...
  • Post in thread: SolArk15k vs Eg4 18k

    Hey everyone, Maybe my inverter is old, I know I am. The temperature rating was important to me as my unit is mounted outside in Alaska. That being said it is mounted along the wall to my mechanical room. We could not put the unit in the mechanical room due to copper and water. I have...
  • Post in thread: You won't believe how much power it takes to do laundry

    Here in Alaska, Gas used over electric for drying clothes. Cheaper so I am told. That being said, drying racks work the best. Bonus you get to add humidity to a dry house for free. Drying racks are pretty cheap as well. Last I heard about 6% of all electrical consumption in the US is used...
  • Post in thread: Sol Arc 15K Can the generator port be turned off and locked in the off position?

    Hey Oldphile, That is not a bill or the price per KWH. That is the price for banking a unit from Solar Generation and taking it back for use at my house. My Net meter fee per unit. Plus 8 usd per month for a solar grid tie. So banking fees are .061 (Distribution Charge)+...
  • Post in thread: EG4 18k, MPPT Range, and PV Array Design

    May I ask if you are mounting your EG4 18k outside? I saw you set -40C as your low temperature extreme and the EG4 18k is only rated to -25C.
  • Post in thread: Sol Arc 15K Can the generator port be turned off and locked in the off position?

    Huh, where did you get 15 cents from? 21 cents a KWH where I am at. Plus I have 2 EVs. They perform terrible in cold weather. Vampire loss is extreme. I need lots of KWH and the grid tie is likely to close. 8% increase in rates coming. So I installed solar. Those who went before me in...
  • Post in thread: Sol Arc 15K Can the generator port be turned off and locked in the off position?

    Oldphile thanks for the info, As for inverter it is about 2 or 3 feet off the ground. Snow could be an issue but not up against the house. Over hang helps a bit. Also a bit of a hill there. Radiant heat helps a lot. The first 2 or 3 feet all around my house will be green year round...
  • Post in thread: shed solar

    Sorry I am late to this post, Your solar shed, does this price include the shed? What is the size of the shed? Typically under 200 sqft and you do not need a permit. Will the shed be insulated? What is the roof angle and type? "A" frame or "one way?" Are you planning to heat/cool the shed...
  • Post in thread: SolArk15k vs Eg4 18k

    Hey Shadowmaker, I agree the snows reflection of light and colder temps increase production more than most people account for. My few but growing number of solar friends in Alaska stress that as a big benefit having snow reflect the light . My solar shed dreams...
  • Post in thread: Sol Arc 15K Can the generator port be turned off and locked in the off position?

    Oldphile, Sorry I missed the part about the loads. My home is efficient as we did a energy audit a few years ago. We averaged 8 to 12 kwh a day for 3800 sqft. Then we got 2 EVs. Now we average about 35 to 38 KWH a day with some days passing 40 KWH. With free charging at my work it helps a...
  • Post in thread: SolArk15k vs Eg4 18k

    Hey Shadowmaker, I do not intentionally heat that areas around my house just excess or a biproduct of my radiant system. I doubt it gets to the 140F temperature of the water being sent through the pex and concrete. Pure accidental conduction. I need just...
  • Post in thread: SolArk15k vs Eg4 18k

    Hey Everyone, I am stuck with Sol Ark as I was concerned about the minimum temperature. At -25C or -13 F as a temp limit, that will be an issue where I live up north. On windy nights during the winter we can dip below -25C though not by much. Has anyone tried using one...
  • Post in thread: Looking for a decent inverter

    I did not say it was decent, only said it was on sale. I let Amazon shoppers do the ratings.
  • Post in thread: MMPT management to limit the amount provided back to the grid in a grid tie

    I have Sol Ark 15k and 2 active mmpts . Is it possible to add third MMPT for only battery charging or off grid use and use other two for a grid tie (limit 10k grid tie)? My grid tie is only for 10kWH max. I wish to add another 5 KWH MMPT on the third position matching the other two. So if I...
