Might get to test the hurricane tolerance of these mounting systems soon

Depending on whether or not the storm stays on the present track,
the aerodynamic characteristics of the ground mount and roof mount could be tested.

Not too worried about the ground mount, lots of concrete, deep piers.

The roof mount (unoccupied shed) is bolted through the corrugated, galvanized steel
into the trusses.
I used 3x the mounts that the SnapnRack design specified, because...hurricanes

You should use 3x more zipties or straps. There is a reason wire management is the achilles heel of an array inspection - abrasion due to wind.
 
Hope things work out.

The only thing I can think to add is pool noodles under the edges. Could prevent wind uplift and wire abrasion. Couldn’t hurt.
 
Glad I used the IronRidge roof mount system and designed and installed to 145mph as code requires.

I'm currently in the bulls-eye of the track, but with 30 years in Florida, it never seems to follow them, even when even only 4 hours out.

11kw of solar, 10kw of BYD battery, with 6kw Soils Hybrid 240 split-phase for home loads ready for whatever may come my way.

If you have batteries make sure to charge them up fully and leave them in reserve.
Several installers have told me that a roof with panels on is stronger than one without. It’s going to be a bit of a gut churn for the next couple of days.
I have been through six of them so far and most of the well constructed house had minimal damage.
I think Canada is going to get the biggest hit. When your homes are not built with hurricanes in mind the results are not pretty.

Good idea, no Sun today, or for the next 2 days.
The MPPT controllers normally charge the batteries. I don't use the inverter charging function.
I put the MPPT chargers in "standby", and turned on the charger in the inverter, filled the batteries from the grid, worked great.
Expecting the grid to go down tonight/tommorow.

When is Canada getting hit with a hurricane?

Hurricane Ian's 'extremely dangerous' eyewall -- near Category 5 strength -- is moving ashore in southwestern Florida | CNN

Hurricane Ian's "extremely dangerous" eyewall -- just shy of Category 5 strength -- is moving onshore in southwestern Florida, with the storm poised to inflict "catastrophic" winds, storm surge and flooding across a large portion of the state, forecasters say.

What a beast :(

Typhoon Noru (110 mph sustained; 160 mph gusts) just left us, was pretty bad in the north. Ian is stronger than Noru.

Sounded odd to me too, what a surprise to find out via Google that there's been more than a few hurricanes that hit Canada! Still doesn't sound right to me ;) but then again I'm from the PNW and know nothing about hurricanes


Good luck op!
 
Reminds me of the movie Pacific Rim, where the biggest ever Kaiju was a Category 5. Only now we don't have Jaegers to fight.

The movie also described a "double event" (dual Kaiju's); it has been happening in the Philippines quite more often recently. Crazy.

Double Cyclones Strike Philippines

Typhoons Mitag (right) and Hagibis (left) flank the Philippines in this image taken by MODIS on November 25, 2007. At that time, Mitag was about to strike the Philippine island Luzon with winds of 150 kilometers per hour.

I grew up to hurricanes, as I got older they became less scary. After certain age it was more of top the generator off, fill the freezer up with ice and the fridge up with beer, we are staying :LOL:
I don't miss them, glad to deal with blizzards and wildfires.
