 I just had a simple PV installation: 3KWpp PV, 1050Ah 24V Battery and a 2KW inverter fro...

I would put a triple pipe conical anchored or non anchored base on that or it'll fly away. Fallover is what I meant. Really though, spin out of control and rip up the base. Never built one myself so what do i know, expensive unless you got the skill. P...

The fridge alone uses about 1.4 kwh a day according to the pdf I downloaded. That's something you have to size for unless you have a generator you can use to boost the batteries if needed.

The batteries will be the expensive part unless you get a gentl...

Kestrel has a passive pitch design.

Hugh had some positive comments about it:

It looks like it has the "convential" valve head on it.  The one you built last year, that is.

How far have you pursued your rotary valve concept?  Is it ready to try on the supermileage?

That's a nice setup! It's also nice when the shipping company sends you free insulation  .

Yes.  Nearly a work of art just as it sets.

Historically passive pitch mechanisms have been mixed blessings.  They offer arguably better, smoother control than furling machines.  They do however, increase weight and complexity, and without proper maint...

No boB,

At the current time, the usage is hovering around 700w.. the temp of the heat sinks is 24C and the caps the same. Fans are not turning, and won't until 29c, then they will start to circulate some air. They are 120mm.... ambient temp is about 16...

Those are very well matched panels. If you double them up you will have more than 60v input, so if you do that needs to be done to code to protect yourself (insurance issues) if something goes wrong. If you simply place all 4 panels in parallel at 44vo...
