OFF-GRID POWER - $500 (Sturtevant)
QR Code Link to This Post
It AUTOMATICALLY provides power whenever the power grid goes off; and, of course, other applications when there is no connection to the electric company grid at all. UNINTERRUPTIBLE with heavy-duty surge protection.
The unit was manufactured in Necedah Wisconsin 54646 before the company moved to North Carolina, after Eaton bought the company, but now they've already moved back to Janesville area of Wisconsin a few years ago, currently "N1C".
This thing is heavy and big, (even though it now doesn't have any of the four original internal 12v gel-cell batteries.....about $ 120 each), thanks mostly to the massive inverter transformer, so you'll have to come over to pick it up with an SUV, van or pickup truck, here in Racine county WI. Two guys can lift it, so I'll help you load it into your vehicle.
The unit features the very heavy huge ferro-resonant transformer that filters out line noise and surges, providing sine wave purity which is computer and hi-fidelity (music) grade.
The unit's case was customized to have four wheels (2 swivel) to make it tremendously easier to move around for cleaning carpet, and accessing the cables at the back. Also the steel case was beefed-up and has two eye-loops at the top each with a square backing plate (keeping in mind the center-of-gravity), enabling the unit (with or without the internal-type batteries) to be lifted with a hoist as well. I modified it with the circuit boards removed, and covered the transformer with a metal shield, to keep them safe during welding, etc. The case is clean inside and out.
The batteries got weaker, and are not included, and since then, they've already been recycled. All four did fit nicely at the bottom of the case. You can buy exact replacements, OR you can get much larger batteries to mount outside of the case in their own cabinet; which was what I was planning to do, to be off-the-grid. Economic downturns forced me to change plans, so I put the unit in storage for later. To make sure there was no atmospheric oxidation corrosion, I kept the circuit boards disassembled from the unit and packed them in sealed bags. Prior to this, I drew a couple of physical wiring dress layout diagrams for reinstallation of the circuit boards; which are shown in the photos (not complicated at all).
Some used units with used batteries sell for $2000+; this is reasonably priced at $500. Phonecalls/texts from local WI/IL area codes only; and because of its heft, I will not ship it.
TEXT me, please, to get the conversation started. (I get too many spam phonecalls). Thankyou.
