Gotta tell you that this video is pretty much a waste of time. A bunch of numbers written on a white board. Then a price comparison. Absolutely of no value to a site that wants to set up a battery backed grid tied hybrid system. But you keep click fishing.

I need some help figuring out my solar needs and what I build myself with an electrician. Thank you

Looks like a great battery and it comes with a 6 string inverter! I was thinking of getting micro inverters for our apartment but if I can save money and still have just the battery and a gateway in the garage then I'm happy. Good to see they have rapid shut downs.

Not having Micro-Inverters, is a deal killer for me.

Nice overview and thanks for correcting previous info. That's a righteous thing otherwise, bad info piles up.. Hey, so one thing I'm always interested in is where the company is based and also where it's manufactured. I know, I can look it up but I think it's important in a side by side comparison. And besides employing my 'neighbors', it also may have warranty implications. I always prefer to buy American, except for an occasional Honda motorcycle... Thanks for your efforts! N

Why would different strings need to face the same direction? PW3 has 6MPPT connectors. Wouldn't each string wired to different MPPT's not care which way the other one is faceing?

I was deciding last month between these same 2 inverters... I ended up going with EG4... a MAJOR factor was the friendly support from their tech support people, answering questions before the purchase and this continued after as well

For the love of all that is good, please put down the pointer! It's really annoying.

Good video, you know your stuff. Please put down the pointer when you talk bro!

Sol Ark hay a better tech support. EG4 has a terrible tech support. I have experienced this.

True, hopefully they will be around for a long time. They seem to have lots of sales.

Okay , these are the comparisons numbers for now , could change!

How are you protecting electrical workers from backfeed during storm restoration effors?

How much energy (in kilowatt hours) can the power wall 3 actually store?

You seriously need to stop bouncing back and forth, it's really distracting from your message.

Thank you for breaking down the comparisons between these two units. I personally think this is great information for anyone who's been debating or battling the decision to make between these two units. Keep up the great content!

Did you say mins string voltage of 60v??? That’s wild! With string voltage flexibility that low you really wouldn’t need module level mppt

Thanks for this video. I think Solark wins.

Thank you. Well done.

Respect. Thanks for clearing this up for us!

It would be good to look into the leg imbalance on the Sol-Ark. I know the EG4 can do 8,000 watts on one leg. and can hold 14 kilowatts for 10 minutes

Also, doesn’t Solark have an EMP-hardened inverter, too?

Luxpower Company have been in business since 2017. 18kpv max peak power is 24kw. max continues power output with solar (18kw) 12kw ac output plus 6kw charging power of the battery.

Thank you! Very helpful and easy to understand. Love the Pro and Cons explanation and examples given. 👍👍👍

EG4 is made by Luxpower. They have been in business since 2017.

I would strongly encourage anyone looking to buy EG4 to look at forum posts of end users for their specific product. Regarding the 18kpv, I've read posts on DIYSolarforum that it's ability to push power back into an existing panel "meter zero" hasn't worked for some users, and they had a rough time getting support to fix it. The support for EG4 by Signature Solar is terrible. You can't just call up Signature Solar and get someone who knows how to fix or address any issue with an EG4 unit. For Sol Ark, the Vice President of my region emailed me regarding a question with my Sol Ark 15k the same day. Even our friends in Taiwan with MPP Solar respond faster and more accurately for issues with their units. Maybe the 18kpv is massive improvement from previous EG4 products, but to me it's not worth the headache. I'd rather go non-grid interactive with the less expensive EG4 6000 xp or get a Sol-Ark. I'm very happy with my electric bill using the "Limit Power to Home" feature of the Sol Ark 15k.

Thanks for clearing up the misinformation.

Outstanding....great comparison. Would love to see AC vs DC coupled systems compared (Enphase 5P vs Tesla PW 3...with pros and cons).

NHX-10kW - Split Phase 120V / 240V , Outdoor rated, grid Interactive, UL Listed, 4 PV Inputs to 500V,

Why not just use smart outlets to control low priority loads? Even a dozen of these would cost next to nothing compared to the cost of a smart panel plus installation. Plus many homes are not wired to breakers in a logical enough fashion to come close to the granular control of smart outlets.

This may sound like a strange question, but if I get a Powerwall 3, do I no longer need a whole house surge protector like an Intermatic? IOW does the Tesla gateway handle surges from the grid or will an additional whole house surge protector be beneficial? I live in central Texas and and we're getting some weird blackouts , brownouts...and surges where some breakers get flipped.

Have a 8k ask my inside link about upgrade to a 10k said don't, why? The difference is all software

Overpriced and impossible to buy you can order one but when you'll get it no one knows meanwhile I have zero electricity. Tried getting a powerwall in 2016 & again in 2020. Ther are better cheaper and actually available to purchase today rather than order and pray it comes someday

Optimizers could be used in conjunction with the Powerwall 3 correct? That is no different from when solar PV with optimizers sent DC to a standalone inverter and from there to a battery (if you had one). Thanks for the details and the clrificaion on LFP batteries. Looking forward to some future videos of installations with the Gateway 3. We don't have the same meters here in the UK, so it would be Gateway3. Good video, thanks.

Do you happen to know Joe @SolarSurge ?

This guy does not know what he is talking about. Do not do business with him.

Do you install systems in Johnson City Tn?

Tesla Energy! 😍

Awesome video! Clears up qiestions after your BG3 video. And many ither questions. Like and subscribe! Only thing missing was VTH and VTG, VTX. Hoping this is all included at some point. Have Cybertruck soon which includes paid for 3V gateway. There are enormous advantages to having PW3 in system. 3V gateway will be PW3 compatible at some point, but not now. Tesla said that I could do 3V gateway now, but would require special support for commisioning to disable 3V site controller. They recommend I instal BG2/3 or Backup Switch instead. Any thoughts about which gateway to go with? Mostly concearned about future compatability with VTH and VTG.

Can the pw3 be an off grid system?

If you have an EV can PW3 charge it DC without inversion? Straight from the panels or battery?

Where can we order the Gateway 3?

This is by a huge margin, the best explanation I have seen on how Powerwalls, and in particular, the powerwall 3 works. I can't tell you how many 20 minute videos on KZfaq I've come across that tell me nothing more than the bold text on the Tesla website - which only takes 5 minutes to read. I really hope my installer is as well informed as you. On my next phone call, I'll now have lots of intelligent questions for him. FYI - installing Solar in CA is just plain awful. Powewalls need to be spaced 3 feet from any door or window, 3 feet from a gas line, and here's the killer - 3 feet from each other. You need a pretty big, windowless house to install more than one or two Powerwalls. The utility only buys back at 7 cents per kwh. But charges 60 cents peak, and 24 cents off peak. You basically need to be 100% grid independent.

Great video. I’m still a bit frustrated with all generations of Powerwalls. They are far too expensive for most homeowners. I was recently quoted a price of $1,000 or so per kWh installed. To go off grid, keep power through the winter, and top off an EV at night, the average homeowner will need at least 50 kWh of storage? To actually disrupt the electric utility cartels, battery storage will need to drop by about 80%.

Can me and a couple other neighbors string these things together. So that we could share the 30 KW of PV. Now that would be an interesting microgrid. Seems like the redundancy would be nice.

Why use this over a backup Switch? Only reason I see is V2H with the cybertruck

The AC coupled system is also safer than running high voltage DC cables, where DC arcing from damaged cables caused by rodents and mechanical wear can cause roof fires and electrocution risks.

Another great video. Thanks.

Wow, this is a great idea! So simple.

This is a great video! Thanks for putting this information out. I am ready to install solar and having well presented information like this is so helpful!
