tesla powerwall 3 is $11,200 after incentives installed.
(1) EG4 18kPV + 1 x EG4-WallMount Indoor Battery | 14.3kWh Capacity is $9400 without installation.
(2) EG4 6000XP + (2) x EG4-WallMount Indoor Battery | 28.6kWh total capacity is $10,725 without installation.

i think i need higher output of the 18k because i have a electric dryer that uses about 5500w and i need to charge my tesla. i don't want to have to plan a time to do one of these things with the 6000k. i know the 13-14kwh of battery storage is very little. so i'm thinking in order to keep the cost low maybe i can get two 6000k with total 28.6kwh of battery. how much would it be to find an installer to install the EG4 system in the bay area in CA?

which one would you guys rather do? when you buy EG4 systems, do you get a tax credit? please help me decide. thanks.

If you can do the install yourself, a system besides Tesla lets you have more control.

To me, I could not do the permitting or climb on the roof to do the install in any reasonable amount of time, So I had an Outback system installed.

For planning, I go with $12k for 10 kWh of Battery pack installed, and then $15k per 5 kW of battery installed.

I don't recommend having someone install an EG4 for you unless that is something they install. They may be unfamiliar with the equipment for the strategies it uses.

For my install, cost of equipment was such a small factor compared to labor, design, and permitting, so I don't think you will save that much by going with a cheaper system since most of the cost is elsewhere.
 
My last system was Solar City installed and was done very well. Currently in process to install a Tesla system.
I recommend 1 or 2 battery expansion modules to go with PW3.

For the other options I would talk to a few installers and get a quote. I don't recommend buying equipment and having someone else install. Let them quote the whole package. Otherwise there is no practical warranty.

Virtually any working system will qualify for the credit.

I went the Sol-Ark route. If your going to DIY in Ca I highly suggest that you make sure everything you buy is on the approved list for Ca. If an installer is putting it up then he will make sure that it can pass inspection.

After tripping my Growatt 12kw inverter multiple times when running the dryer + charging my car @level1, + running the microwave, I realized that the 6000XP could NEVER handle my small house. So, don't do it! Unless you have the space on your wall to install 2 of them. And the patience to do extra wiring.

Btw, these systems are actually very easy to install once you learn how to hoist heavy objects up your wall. If you don't want to tackle the install yourself, maybe go with Tesla. My 2 cents!

You should consider the EP Cube too. I bought a big one yesterday from Signature & it shipped today. I'm getting the 15.2KW with 39.2KWH battery version. I will get a 30% Federal tax credit & $200. per KWH rebate.

EP cube good compromise and needs to be mentioned in these comparisons. Loving mine so far. I'm running entire house off-grid for a while now. Very diy friendly.
 
You can install the Tesla Powerwall yourself if you want. If you do the PowerWall 3, you shouldn't add extra Tesla battery expansion yet. The cheaper to add DC coupled battery expansion will be out in the next few months.

The Powerwall's are amazing. And they support the new initiative for providing power to the grid during grid black start scenarios and other emergency situations. My power company will give bill credits if you let them have temporary access to your Powerwall for short periods of time. The credit is $52 per month per PowerWall 3 you have. And the credit will offset more than just energy usage charges. It'll offset the other fixed fees as well. I'm sure other utilities are in the process of rolling this out as well.
