Worth noting, it takes more than "just talking to your utility" when back feeding power. The "gateway" box that is installed with a powerwall system contains an isolation contractor that allows you to island your house when the power goes out along with distribution breakers. Most utilities require this UL cert. box to allow you to connect a grid tied inverter if you want backup power. Otherwise the inverter just off when the grid goes down. It ensures that the inverter doesn't backfeed when people are working on the power lines.

I have been looking into solar, inverters, batteries, etc… every video I see, I have to listen to 10 too 20 minutes of monologue, only to find out it’s not what I am looking for. You answered my biggest questions in the first two minutes. I paused, liked & subscribed. Now, back to the video. 😂👍

Something I want to mention about doing the electrical yourself. If you are unsure on your ability or worried about insurance. You can hire a electrician to inspect the work you did and sign off on it. Rather then them putting in the time.

I'm an electrician and this system seems easy enough for talented homeowners. One thing I would suggest is that you guys inform people that you have construction experience that makes these projects easy for you.

EG-4 18KVP inverter and 14.5KW EG4 power pro battery is $8500. It's by far the lowest cost UL9540A ESS certified inverter and battery combo on the market. Adding more batteries is $3599 for every 280 AH or 14.5KW battery. The days of price gouging solar customers by manufactures, and solar contractors are coming to an end.

Very good! I had Powerwalls installed at our previous home. I may just do it myself your way this time. Maybe.

I installed this same system in my garage. My main issue with these batteries will be in the winter months. I was mislead by the sales guys that they could be used within certain temperatures and outdoor rate however I later realized the temperature will need to be around 40 degrees F for charging. Now I need to add a heating system around the batteries. Too bad they don't include heaters like other similar batteries on the market. they claim they can be installed outdoors however they neglect to mention that your house needs to be in a warm climate where it does not dip below 32 degrees.

Congratulations for the professional research and clarifying presentation

Amazing timing!! I’ve been thinking about this for hours last couple days!!

You are guys are amazing as always!

PW3 with Backup Switch is the killer app for whole-house backup. Drastically simplifies (reduces costs) and speeds up installation. I was going the DIY route until I priced out the additional labor and materials to do what the Backup Switch does. The Backup Switch offset the cost savings of less expensive DIY batteries and allowed me to let Tesla do the permiting and installation. Honestly, was very surprised how competitive Tesla's pricing is - was cheaper than any of the 6 other quotes I rec'd, by as much as $15K.

This looks so simple to install. Nice design!

Wow guys, you are super cool 😎.
I was thinking about solar powered system, but now i know what to do and how to do it.
Since in Uzbekistan our grid system allows to sell excess power to the grid and currently payback period is around 1000 days for just On-grid solar without batteries.
But I would install battery also, since I got 2 fully EV vehicles 🚗

Accidentally clicked on this video,
Glad I did. Great info!

[npanarooptonlinenet]

Excellent job guys, really done well-thank you.

[emceh]

PV roof sounds awesome :) upload ASAP please ;)

New subscriber. Amazing video. I'm looking into options for my parents for their house. Thanks for all the information.

314ah MB31 EVE cells can be had for $89 each, 16 of those, a DIY battery box with JK inverter BMS for $400ish from China gives you a 16 kwh battery for around $2000.

LuxPower is similar to the MultiPlus II from Victron, but the Victron system is more modular and works with generic 48V batteries. For example, with Pylontech US3000C LiFePO4 3.5kWh, which are significantly cheaper and more redundant (because each has its own controller). The wiring is just as simple. This is not meant to be an advertisement, just another example. For DIY, I would strongly advise against DC strings. I like to do everything myself, but even with LuxPower, you have to connect high DC voltage to land in the correct MPPT range. High DC currents are EXTREMELY dangerous and need special protection. For DIY, I would always recommend microinverters because you connect low voltage on the DC side, and no AC flows as long as the fuses are off as usual during installation. Besides the added safety and redundancy, you can also start cheaply without a battery and battery inverter in the world of photovoltaics and add a battery later.

Super-good video, guys. Tesla needs some competition. I'm already stuck in a dual Powerwall III contract waiting for my ding-dang Powershare Gateway III that is supposed to come with my FS CyberTruck that I took delivery on April 27.

For my 3 off-grid observatories and employee housing, I'll be doing Ethos upgrades to replace Lead-acid, AGMs, Jita & Temgot LiFePOs (I've tried every kind of battery storage for my solar arrays over the last decade) thanks to you guys and this video.

Just perchased 5 eg4 powerpro batteries 14.3kw apiece. So 71.5kw total for $17, 193.60 or $3438.60 per 14.3kw battery. delivered to my garage. And an eg4 18kpv inverter for $5, 199. And 30 390watt panels $3568. I will be installing it all myself. Have to have a licensed electrician hook it up in my circuit breaker panel. Will be grid tied. So have to get permits and have it inspected.
The 18kpv inverter will do everything. Grid tie, islanding, batteries, start your generator. Everything. Eg4 batteries have heaters built-in. As well as fire extinguishers. Even though they are lfp batteries.
