Hi francisco.shi , coulomb , If you click the Quote button for a previous post as I just did for Coulomb's last entry above and then examine the quote tag it produces, that gives you the information you need to work out how to do what you want.

Re: Prelude conversion project - some questions

A mould would be worthwhile if you were going to do more than a couple of these I'd imagine. If you're only doing one or two, I think it would be quicker/cheaper to just fabricate it. It's not too hard to fabricate a shallow fibreglass box. You'd just do a timber frame that sat neatly and accurately...

Re: Prelude conversion project - some questions

Easy enough to make into a "tub". Our project was a fresh water tank for our yacht, two compartments, baffle plates, complex shapes. Kaye and I constructed it ourselves after some "training" from our nephew who is a professional shipwright specialised in fibreglass fabrication. Doing a rectangular "...

Re: Prelude conversion project - some questions

What dimensions do you need for your fibreglass lid? I happen to have two or three sheets of vinylester fibreglass made up for me by Custom Mouldings in Henderson for a boat project a while back. We didn't need anywhere near as much as I'd anticipated. Two of the sheets are about 1200mm square x 5mm...

Re: Low Cost BMS for Home Storage Batteries

I guess the circuitry difference between top-balancing and bottom-balancing is too great to be able to include both and switch between the two?

Re: Solar Panel output: Rating versus Reality

Thanks Terry, I managed to separate the two last night, carefully working my hands between the Thermoclear and panel without any curves. I'd avoided any more sun on the panel fearing it might cure the Armourflex further but I'll definitely use the sun to help get the glue off the back of the panel n...

Interestingly, my experience with the Armourflex has not been that wonderful. The one panel I've glued to t...

Ah, I'd misunderstood obviously. I'd thought the differential expansion problem was between the metal of the vehicle roof and the plastic base of the panel. I'd assumed that the expansion/contraction rates of the plastics in the panel base and the thermoclear would be similar. As you say, hopefully ...

Re: Solar Panel output: Rating versus Reality

Hi Terry,

Thanks for that, I've emailed Ampelite's Perth office to see if they have someone that sells Thermoclear near us.

Now I just have to see if I can find somewhere in Perth that sells the glue, I gather you recommend Simson 70-03 or Selleys Armourflex.

Re: Solar Panel output: Rating versus Reality

How solid is Thermoclear Terry? The main reason for my home-made frame was to prevent the panels bending too much while being handled (or wind-blown) but also to leave them light enough to make for easy handling. The frame has turned out to be much bulkier than I would like anyway so I'm happy to di...

Hi Terry, thanks for the detailed post. Your test with Halogen lamps sounds like you're replicating what a good MPPT regulator should do.
