I keep my solar panels in a lead lined vault to protect against EMP. Still not sure why my batteries aren't getting charged.
Not enough acid?
You can purchase a EMP Shield device and install it on your main breaker box. It will protect up to 200 ft of wire in any direction from your panel box. Will protect your Inverter from conductive emp surges including all levels of EMP. Will not protect against inductive on the box itself, however that exposure (just thru the air to the housing of your unit) normally just makes you have to reset it if anything. You can purchase on for the lines from the battery bank if your wires are long enough to be that conductive, and definating get one for your solar panels to be installed at a point before they get indoors with the inverter/charge controller. Check out EMPshield.com . Call and talk to Ben and tell him Robert in Houston sent you. He will cut deals when he sells more than one unit. I bought a dc model for my work van, and one for my panel box.Is it possible to EMP harden a solar system ?
Well.... I don't have panels in a faraday cage per se.... But on the roof I do have them wrapped in aluminum window screening just kidding - but not by much.You can purchase a EMP Shield device and install it on your main breaker box.

The only way to do any better, if you're made of money and a prepper, is to have a backup inverter, charge controller, panels, wiring, everything, in a Faraday cage. I think my wife would call the guys in the little white van with the funny white suits for me if I did that.
Put the whole house in a faraday cage.....Well.... I don't have panels in a faraday cage per se.... But on the roof I do have them wrapped in aluminum window screening just kidding - but not by much.
I think you are supposed to take the acid.I didn't see a fill hole in the solar panel for acid. That must be on the Performance model.
All,
With the current stand of around Ukraine potential conflict with Russia. I would like to ask basic question around nuclear HEMP (High-altitude ElectroMagnetic Pulse) and its impact to our solar panels and its peripheral devices (inverter, solar charger, LiFePO4 batteries, etc.). I read an article to wrap the electronic device with an aluminum foil min 3 layers and place it inside galvanized steel trash can. LiFe PO4 battery is considered to be an electronic device due to its BMS? any idea of how to handle battery? or suggestion? I'm new around HEMP stuff/
Thank you for your input. Will it protect the solar panel diodes when not in used with wrapped aluminum foil? My solar generator DIY is for an emergency only, so they all are not in used. I was planned to stored them all in trash can (wrapped in aluminum foil), except the panels, kind of big.They always used to say that hemp was good for everything hehe...
On solar panels, I've heard that the actual solar cells in the panels don't get damaged with EMP, just the blocking diodes in them can or will get toasted, so keep spares of those. I've also heard of lightning suppressors you can get for the solar panel runs too (Midnite Solar?). SolArk has some kind of suppressor deal their EMP hardening kit comes with that goes on the solar wires.
On inverter, unless you can afford to keep a spare around in a faraday container, then if it is not an EMP hardened inverter, it could be vulnerable I suppose. You could buy a cheaper spare inverter to keep around in the faraday container as a backup for emergency. In my case too, I am trying to make some circuits that will run on DC battery power directly, like light bulbs that run on 12v or 48v.
So I found a bunch of LED light fixtures (light bars designed for 12v-24v vehicle use) that support 9-36v input), I can wire them in series-pairs on a 48v circuit to get emergency lighting going if needed.
There are also a bunch of websites that sell appliances to run on DC power input. And some people here have mentioned that you can put on a whole-house surge protector in the breaker box or something that can help protect normal AC appliances from line surge as well.
Grunfos and other companies make well-pumps like the SQFlex series that can run on AC or DC power (30-300v DC), and can run directly on solar panels. Theoretically, if the well-pump has electronics inside it, it would be submersed well below ground level and should likely be safer from EMP.
Also not a bad idea to have a shallow or surface-level water storage tank as a buffer for easy water access in case your well water table is very deep down or using city water supply in case it stops, you can hand pump or gravity-feed water from your water tank easily if needed.
On my system, I bought spares of each of my 2 types of BMSs, to put in the faraday container (doesn't hurt to carry spares anyways, even if apocalyptic times never happen), I just like to keep spare parts around anyways for fast repairing, and due to supply chain delays... The lithium cells themselves shouldn't get damaged.
On your faraday container, I guess they say it is important to line the inside of it with cardboard layer, as you don't want any of your protected equipment touching the outer shield, but rather insulated from it inside. Some people say it is important to ground the faraday container to Earth ground, but others say it doesn't matter and don't need to ground it.
