anyone have any idea if i keep replacement IQ 8 microinverters for my system stored safely will my system work after EMP and replacing microinverters

If an EMP takes out your micro inverters. It probably also took out the grid.
Agreed. Also, only guy with power in the neighborhood, better have a plan for that too. I would keep all spare parts hidden for a long time till all the battles are over.
Plan on having zero power in your preps. Hand well pump, hand wheat grinder, etc....

Grid tie is not a backup plan.

If there is an EMP, energy is the last thing people in the blast radius need to worry about. I would worry more about the next rocket that is already inbound hot.

A high altitude detonation intended to produce an EMP would be 20-50 miles up. Blast effects on the ground wouled be mostly nonexistent.

Store them in a Faraday cage. If the panels survive (don't get fried either), then you have a fighting chance. All the other wiring and equipment also has to work or be replaced.

It would be like storing extra bullets, in case you lost your gun.
If the gun is gone, you won't need bullets.

I can't imagine any scenario where any entity would detonate a nuclear weapon up in the atmosphere instead of on the ground.
There are nukes that are specifically designed for high altitude detonation for a higher EMP affect. They are low yield but much higher gamma ray output. The gamma rays passing through the ionosphere produce and electromagnetic pulse. This nuke generated pulse is much worse than a solar flare generated EMP from the sun due to the short duration start of the pulse in the very high frequencies. It still has the long wave(long duration) pulse that gets into the longer length wires but the short pulse is what will wipe out chips, integrated circuits, etc....
1 or 2 nuke/EMPs done up in the air will do WAY more damage than dozens nukes on the ground. It would be the only way to take down a well armed first world country. It could be blamed on anyone. All your enemy has to do is sit and wait 6-12 months, then do their invasion into a broken country.
If country A wants to take over country B, it will be a lot easier if a large percentage of the population of country B is dead.
One, or a few high-altitude EMP's could reduce that population dramatically over the course of a few months - lack of water, no food
deliveries, no heat or cooling, disease, probable civil unrest, etc. Studies have shown that a nation-wide grid-down situation might lead to as many
as 8 out of 10 people dying.
A big plus is country A gets to move in and use all those buildings, highways, etc that are undamaged and uncontaminated.
Ground-level bombing kills fewer, requires many more bombs, contaminates and destroys stuff that would be useful afterward.
It's not at all unlikely that country C (who happen to manufacture all the electrical equipment needed to
repair the EMP damage) would be more than happy to send in thousands of troops to "help repair the damage".
I leave it to you to figure out who country C might be.

Carrington event is more likely, and the USA's grids are not hardened for it.
In a carrington event, the national grid will be down for years… IQ8’s would be useless without an island energy setup…

The first question was only part of my inquiry. Don't wish to discuss defense here. I would intend on being off grid. In a rural area far from targets. Have batteries which would not be impacted but would need to stock charging and dc/ac inverters which would not survive. I'm just trying to determine what spares I would need to store. I believe that the solar panels might only need diode replacement. Just looking for advice on what to stock.

You said micro inverters.
Which generally means, dependent on a grid.
I imagine that lead/acid batteries wouldn't be impacted, but don't LiFePo batteries also have integrated circuitry in them?
I think those are what an EMP would affect. And I think you are misinformed about being in a "rural area far from targets":
As for a Carrington Event, that would mostly affect the power lines, transformers, and stuff connected to the grid.

IQ8 maybe works off-grid with Enphase battery system?
But has problems AC coupling with other brands.
A different choice of hardware would be more supportable.
A motor-generator could serve as EMP proof inverter.
PWM electromechanical voltage regulator similar to automotive regulator.
lead-acid battery.
Diodes in PV panels aren't needed except for conditions of shade. And low-voltage array would also be less of an issue.
Vacuum tube radio.

Your BMS would likely get fried too.
OK a hard look at reality. Think 1950's Vacuum tube radios with mechanical vibrator no transistors. AGM or golf cart batteries, dyna-motors. MAYBE some Tier 2 PWM CC in a shielded cage.
Lookup Fairaday cages and faraday bags, no "almost good enough". Paranoia is expensive. Those type of batteries have a shelf life and will need monitoring and replacement.
You need to buy the stuff and set it up and learn how it works and what can fail, there won't be a DIY solar forum.
Think about a 2nd EMP a month later.
