optimizer boards are beefy and no issues with them.

I was using both his and his competitor's 2000 4000 and 2800 watt boards.

I was a little careless with the competitors ibm 2880 breakout board and gave myself a 240 volt/30 amp circuit shock

Even with a one hand no grounding touch it still fucking hurt.

If I remember all of optimizers boards are resin coated to reduce shock risk correct?

Phil, we coat all solder joint with a conformal coat. On the high voltage leads, we use a potting compound with a dielectric strength greater than 800V/mil. I have received some negative feedback on the potting compound as 'ugly' and have noted said concerns (though on a personal level, looks are not a thing for me in industrial situations).

We are partnering with an extruder shop to make a plastic enclosure for the power input boards for mechanical strength and to prevent shock hazards.

Though I do need to give you some flak for this Phil! Never should anyone ever handle 240VAC systems while they are live and energized! That should be assumed, but I am stating this for everyone to know, so that such things are not repeated. YOU COULD DIE!

By the way, I am sitting on 1k of 6P to 6P and 6P to 6P+2Ps if y'all need.

-Optim

I know I got lucky it was 1 hand and I was not grounded. It is the 1 and only one time i ever did a 240 volt shock It was a lot different then a 120 volt.

Was not your gear. After this happened I altered it and covered it with a safety piece of non conductive pvc.

Something to keep in mind is that while a psu may be turned off the power plug attaching to the psu can be live so be careful .

Some breakout boards not optimizers have exposed 240 volt lines so even though the psu switch is off the power plug from your pdu would be live. thus you could be shocked.

At the moment I am fairly stock with power gear. But buysolar my solar array partner is look for spot to expand. maybe we will add 50kwatt 24 hour array to our 15kwatt 24 hour array allowing us to run 65 kwatt of mining gear 24/7/365
