Earlier this year I fabricated a 10kw array comprised of 40x 250 watt panels (5x8). The structure was designed by myself and review/sealed by a P.Eng. Structure is 1.5” sch 40 pipe, panels are back bolted to 2x2 square steel tube. The entire structure is anchored to 12x helical screw piles...

My total cost (P.Eng review/seal, materials, helical anchors, hardware, and Galv) was $7,760 cad which works out to $5,650 usd.

Blasting was $200/hr and the zinc was $0.70 per lb (multiply by the weigh in). My array was 1,728lbs so $1,209 (Cad)

Hi all, I have a unique and interesting opportunity that I am pondering. I have a rural property with an 80’ antenna tower used by a local wireless Internet service provider (WISP). With Fibre To the home coming to our area in 2023 the WISP asked what I would like for them to do with the old...

Love the rig! Looking forward to the results!

Only the horizontals are drilled in-situ but because the three horizontal levels are identical (*and all T-connection holes are CNC laser cut) it could all be drilled at the lowest level.. * I had all the gussets, brackets, weldments, and tabs CNC laser cut to save time and for consistency.

That would be fantastic! Thanks!!

Hi All, hoping someone can help determine the Power Factor (PF) of the Aims CON120AC1224VDC. This is the 12/24v 75A smart charger. If you have one of these units and a Kill-A-Watt can you please measure the input current, input voltage, wattage, VA and P.F. while charging a battery at 50%...

Wow, that’s a fantastic power factor! Im really glad to see that! Must be some active correction. What do you reckon is the overall conversion efficiency? 1131watts in and 1123 out (28.8v x 39A) seems a little off.

Well based on your power factor measurements I think I’m going to get one of those chargers.

Just found that while reading Amazon reviews on this charger, a couple users have already measured PCF and indicated that it is >0.95. Some as high as 0.97-0.98! This is really positive information. That means this charger should work well when running off a smaller 1000w inverter generator...
