Any idea who is the original manufacturer as renogy just buys them branded from the real manufacturer. They don't sell them over here in Europe you only get 220W bifacial.

No, it’s 2kWh per 450W (not 550W) panel and is’t only February!

I'm assuming that you have used the drawer slides similar to that illustrated in the image and are concerned that the carbon steel construction will corrode in the marine environment.

I was suggesting that you might be able to fabricate similar mechanisms using stainless steel cam rollers (mainly used in food processing equipment) and C shaped sections fabricated from Square or Rectangular hollow stainless steel sections (hence SHS and RHS) although any devices fabricated in this way would be considerably heavier than the off the shelf items.

For my fridge rebuild project I used L sectioned frames bent up from light stainless steel sheeting strips and nylon screen door rollers however the frames are not captive as they need to be lifted out for cleaning.

SHS = Square Hollow Stainless? Wow, that must be some profession specific abbreviations as not even Google gets that! senior High School it says.

But yes, thanks for that! I have my eyes on inline skate wheels for rollers; they are rather large but will have better grip… I’m thinking over options so this is all very much appreciated!

The slides have no corrosion yet, which I can’t say about the stainless steel struts I made which we cleaned a couple times already. I should have used carbon fiber
