I found that removing the ground stop the lighting from feeding back through the system and frying everything. It's worked perfectly for the last 20 something years.
Well even nearby lightning strikes and produce a localize EMP. also when lightning strikes it can energize the ground circuit that back-feeds into the electrical panel or anything connection to earth ground. You plan of a tower might work if the tower is 1/2 mile or more away. But towers aren't cheap!
Lighten protection is not a single point solution.. It takes several high points 10' apart... Around the whole area. Then you attach that too the tower...Same thing they do in High rise buildings...Minus the tower...As the building is the tower.....
If the gentleman who owns the property ever want to get rid of it and feels extraordinarily philanthropic, he could really make a grateful man of me by gifting it to me. Don't worry, I will still let you service the SolArk 12k solar system!
Hey You should put a ferrit core on the leads from the solar panels right before they are going into the combiner box for maximum protection. And again right before the mppt converters.
Question, could you put a lighting rod up to decrease the issue with getting hit buy lighting, we had issues in Colorado at times, Dad would put up a electrical pole to be higher than anything out there and insert a rod ten to twenty feet long into the ground to attract the lighting to it instead of the equipment.
I am must have missed something but I am wondering why you didn't run two 9 panel strings parallel? Couldn't you have been good with little loss of power by running lower amperage using two pairs of wire? I am using paired strings of 9 panels through 10AWG THNN/TWNN stranded copper wire to each charger running 323'. Only experienced a 2.2% loss of power.
Any chance you can show some picture of the damage? Even a picture of the solar panel would be interesting to see (presuming there was some physical damage). I presume the oak tree fell during the storm or was a hit from lightning the cause for the tree to fall?
Each solar panel should have a lightning arrester ( spike) rod mounted on the Frame about 5 feet high, the lightning arrestors should have each their 10 foot ground rod. Also there would be a lightning arrestor rod on the highest part of the roof, also abt 5 feet high over the roof and with its own 10 foot god rod. cheers, P&F
I guess my 7m x 6m steel shed, which the racks are bolted to, isn't enough (beside the 90cm grounding rebar out the back). Oh wait- have had lightning hit the shed twice, with nil effect- i better do what the internet scientist says.... I guess some people know waaaayyyyy more thanks the Internets. Qld, Australia for reference (waiting for the "oh but! in my county"...)
I automated my change over switch by using a 4 pole contactor 2 no 2 nc contacts with a 230 volt holding coil fed from the inverter output , when the solar output goes down it deenergizes the coil and automatically connects to the grid. When the inverter output is restored it energizes the holding coil and switches back to inverter power.
what is the benefit/issue regarding having balanced PV input to the 2 MPPTs. I presently have (1) 10 panel string on one MPPT and (2) 7 panel strings on the other MPPT. Considering getting 4 more panels to have 2 pairs of 7 string panels. Total 28 400w panels is 11.2 kw.
Honest question. Why use carbon-enhanced lead batteries which will operate from 85% SOC to 50% SOC, yielding about 1/3 the nameplate storage, rather than your favorite brand of LFP batteries that will operate from 90% SOC to 10% SOC? The higher usable amount of storage would allow for a smaller bank but would effectively yield the same amount of storage, and cost about the same as the carbon enhanced lead acid batteries. Am I missing something?
@@guytech7310 Yes you can harden the LiFePO. With TVS diodes (for speed) and MOV’s (for current) against lightning, the number one problem. As long as you are off grid a Carrington event is a non issue. As for a HAEMP event, the voltage rise is too fast for anything you can buy.....except spares. (BMS + capacitive active equalizers)
@@SkypowerwithKarl TVS diodes are fast enough for NEMP. Most of the datasheets list NEMP protection. MOV's will not protect against a direct lighting strike. I would recommend avoiding MOVs since they quickly fall since they are limited use devices. en [dot] wikipedia [dot] org/wiki/Nuclear_electromagnetic_pulse "The E1 pulse is the very fast component of nuclear EMP.

What is the price range for a system comparable to this one? If I thought I could be completely off grid in the 20k range, I would seriously consider it, but I suspect I couldn't come close to this system for that.
All depends on your needs. The Sol-Ark itself is already $7k or so. 18 x 300watt panels adds another $6k. Battery bank 16x 12V LiFePos4 4S4P ~ $16k and misc items at $2k. Without labor or as DIY we are around $31k. It’s the price of independence
Cost largely depends on the size of your panel array & how big your battery bank is. EMP Hardened Sol-Ark is about $7K. I have about $7K in batteries & no panels.
Any reason why Sol-Ark doesn't focus on EMP hardened lithium LiFePO4 battery solution (w/ EMP hardened BMS)? They provide more cycles, deeper cycling, smaller footprint, etc... I guess Sol-Ark would have to answer to that, but I'm just wondering, as I am considering to purchase a Sol-Ark 12k inverter, and I already purchased lithium battery bank but my BMS's aren't EMP hardened.
It’s done all the time, ever been in a hospital power plant, water treatment plant, ect... lots more water lost more electronics and much higher voltages
Freezer voltage. According to the spec sheet this freezer is 12/24 volt only. In the video you said it was 48V (battery bank voltage). So what is actually going on?

Sounds like they could use a well placed lightening rod, maybe even on a tower...

Next year I'm going to have you put my system in..

You forgetting that lightning can back feed from the ground. When a lightning strike happens it energizes the local ground at a significant voltage.
I have a 32 panel solar array with no battery backup I can only imagine what this runs!!
I automated my change over switch by using a 4 pole contactor 2 no 2 nc contacts with a 230 volt holding coil fed from the inverter output , when the solar output goes down it deenergizes the coil and automatically connects to the grid. When the inverter output is restored it energizes the holding coil and switches back to inverter power.
Would be cool to have a 48V washing machine and Hydronic Clothes Dryer. you could use it to heat the hot tub too.
I love all your videos

You can't EMP harden LiFePo's.
@Thomas Chrombly I'm afraid not, ask Engineer 775. He's the one that said you can't ! :)
@Thomas Chrombly Easier option is to use TVS diodes and Ferrites on the battery terminals.
