So... I have these two Sharp 123 watt panels hung on the interior wall of my workshop. 'Prepper Art' and since the first day testing they've never seen sunshine.. . Just waiting for some needy situation.. . Bought back in the days of five, six, seven dollar per watt PV, yeah.. . at $4.80 per...

As I started reading this thread the thought 'ask about mouse pee' popped into mind, though no one could be as careless as me... plans changed and after seven Minnesota winters the 5548 I'd nabbed was totaled - I now have a coffee can full of really expensive stainless hardware & a box of misc...

Okay that is $15 saved from first one bought in December... Beware, Victron is addictive.

Z i p p e r . Name comes from 1923 galoshes brand with a new one-handed fastener where the idea really caught on....

Automotive stuff is not constant duty - 100,000 miles at 55mph equals about 75 twenty-four hour days, and the radiator fans might see 1% of that spread over years of service...

Catch the cold air pooling out aways a bit in front of the evaporator and most any small fan directed flat across the floor makes a conveyor belt to 'mound' up cold air on the far side & gets more hot air back to the evaporator... 1915 farmhouse with afternoon/evening sun heated walls that would...

A final monitor point is heat rise on extended run time to 'find' a 100% duty level - everything kitted together and looking so fine means squat if one is approaching winding sheath insulation limit, and reusing chinesium xfmrs means an unknown variable...

Noalox... used it on 750v cap banks that pushed & stopped 40-ton rail cars, we disassembled and cleaned connections every two years (180k miles)...

Yeesh, hear hoof beats and think Zebras : ) Could be Cat-pee-from-the-factory... Chinesium plastics & quality control: could be an excess of flame suppressant additives such as Antimony used industry wide in IC & SMD bodies, could be plasticizers mismixed and equalizing, could be excess...

Trace : anything with that name on also has some serious years on it - the huge electrolytic caps (at a minimum) are ripe for drying out & decrease in capacity, at least they are stand alone and easy to test / replace... I've also seen where over the years repeated condensation drips have...

True swaging liquifies the soft copper and bonds nearly as a weld would - introducing tinning metal whose electropotential series react below Cu would be such small proportions any nodules would housekeep to keep the copper pristine - and/or heavy plated lugs on bare copper strands that do...

I've seen traveling RVs that somewhen got a refill of suppliers' tank dregs, enough the ammonia-cycle burner & target heat plate are smothered in a oily carbon velvet that halts decent heat transfer - a gentle brushing to get pilot light flame reshaped back as intended & the lower flue cleared...

Yow that must feel good :) I had a buddy get inspector snubbed when his disconnect(s) did not break both (+) and (-) simultaneously... naturally he spent more money to make that go away : / Is the green box off a ways behind the full array photo your utility powerco's distribution transformer?

Overkill IOS app is *my* hero! ( JBD 150A BMS) Rushing to skip town up north with a blizzard forecast I somehow let my Vans 300ah inverter bank get discharged, probably failed to swap out a powerstrip back onto grid and a 280w heater chewed it down... Left at midnight in sleet & snow and got...

Did I see mention of maximum DC current for wire design spec is X 1.25?? A 125% factor accounts for under certain conditions irradiance/temperature lower than STC, the effective short circuit current may be higher….
