Hello All,
Hope everyone is safe and healthy.  As of today we are supposed to stay home for 21 days.  God has spoken! (Or at least the Governor of Idaho)  That tearing sound you are hearing is the shredding of the constitution.

Since last posting, finally got this big powerjack into its place, connected up all my fan controls, and set up to run half the house for first actual load test.  Ran a minute and a half, then blew out all the led light bulbs in my basement.  Shut it down. Cussed a little.  Hi voltage episode.  Now output voltage drifts around from 204 to 248 as read on the front lcd screen (with no load) so output voltage control is kaput.  Voltage is probably spiking much higher than what the meter shows to be blowing out led bulbs.  Very disappointing.  Later discovered a fried surge protector and my old 1990 garage door opener was toast. 

Spoke first with Sean at Genetry Solar (powerjack warranty repair guy).  I told him what happened and about the imbalance of the 2 mainboards and he said there is nothing in the powerjack control board for balancing the two mainboards.  He stated that sometimes (in his exprience) the 2 boards tend to fight each other.  He also said for his own personal unit he has removed the second mainboard and runs with just one. I was thinking along those lines already.  Now its definite.

Powerjack is sending me a new control board, so will wait for that.  While waiting will be removing second mainboard and rewiring another little issue I didn't notice before.  Some bright boy at powerjack thought it was a good idea to connect the 2 breakers on the front panel in parallel!  Might as well have no breakers at all. 2 breakers wired in parallel means its likely neither will ever trip at rated value.   I usually rewire the battery charger breaker into the L2 leg since I always disconnect the battery charge setup on my powerjacks.  This unit didn't have battery charge function (fine with me!) so I get 2 breakers in parallel on the L1 leg instead.  And these guys are the experts?  Makes me feel a little better about my own stupid mistakes...

Anyway, since will have just the 1 mainboard in the case, might turn the fan on the empty side around and use as an exhaust fan.  Alternatively, I'm considering not using the top cover at all.  Instead building an exhaust plenum over the whole top of the unit from styrofoam board and piping the hot air outside.  Add a separate input cool air plenum from outside to the back of the unit to keep my utility room from cooking up (as much) in summer.

Frackers,

Thank you for your note.  All understood.

I am fishing around the Internet to ascertain whats likely to be useful. Some Free CAD software options seem to offer processing software. but the small print often fails to make mention of a printing option.

No doubt I will sort myself out in due course.

Trust you are well.

I have now reach 71 years of age and feel it!

Regards,

David HK

QCAD and FreeCAD come to mind - you'll need something like ODA Converter (formerly Teigha Converter) to get to/from DWG files that AutoCAD uses, unless you can export as DXF.

I have recently purchased a new HP all-in-one computer with ready installed Windows 10 software.

In tandem with the above I have a very good Brother MFC-T4500DW printer, scanner etc.

It's all working very well.

My previous computer runs on Windows XP and still contains Auto CAD 2005 and other programmes which run and work normally.

Mr AutoCAD found out that I was running my AutoCAD 2005 on my new computer and has somehow sent me an e-mail which may have contained something nasty because my perpetual license AutoCAD 2005 was extinguished on Windows 10 at the end of January 2020.

I want to avoid purchasing or subscribing to AutoCAD software and would like to enquire if any reader is using "free" CAD software and can they recommend anything in particular.

My old AutoCAD files on the Windows XP machine need to be printed occasionally so any "free" CAD software that can print DWF files would be just fine.

Regards,

David in Hong Kong
