Thanks Gents, To add some additional detail. When I say peak shaving, I mean I am looking to reduce the grid consumption during peak hours by supplying partially from the 30kwh battery bank (discharge up to about 8kw in all of the peak hours which equates to a 80% reduction in peak usage from...

Thanks. who quoted this? if i could get similar then definitely an option. still concerns wrt peak shaving functionality and fail over condition

Can you provide the wiring configuration for your set-up please? Any push back from the utility? When you installed did the utility provider have to hook up from the meter to the inverter? Thanks

i was only asking for the model to help me get started in looking at the brand. i know they are high end

Hi all, New here and located via Will's YT channel. Awesome content Will. I am seeking help on designing a grid tie battery system...all help welcome! I have already designed and been approved (twice) by APS (AZ power) for a grid tie system but didn't execute. Watching Will's channel, I need to...

Hi, I am edging closer to buying EG4 18kpv with EG4 battery rack and 14kw of solar panels. My usage profile is heavy with high loads at slightly over 20kw in any single hour in the peak of summer. I am looking to have the EG4 manage the load by simultaneously distributing solar, battery and...

Hi all, new to forum and to solar. I am about to pull the trigger on hybrid system and battery but wanted to poll the experience on the forum. I am already approved by AHJ and Utility for EG4 18k plus EG battery (30kwh rack) with 14kw array but am second guessing myself. Questions to this forum...

any chance you could post the 3 line diagram?

where did you price the powerwall 3?

I am trying to navigate similar design issues with a 400A main and 2 200A branches with the second panel remote from main. I have 3 A/C units hanging off each branch and during summers in AZ, all 6 could be turning on simulateously.SS had advised they were working on the 'design' for this...

Looks awesome. Can you provide more details please on the install. The 3 line diagram would be really helpful. I have a 400A main with 2 200A branches. I have asked SS what the design should be in this instance but not received a response. Do you have 2 independent systems, one for each 200A...

I have considered both scenario's and for my situation where the second sub panel and second array are distant from the first then 2 independent systems seems more logical. It duplicates emergency shut off's etc but keeps each system dedicated to the branch its supporting. I will have to see if...

Thanks. Which schneider model is equiv to 18kpv? Any other differences?

Thanks. If the inverter were to fail, is grid supply shut off?

response from sol ark 2. If the inverters are paralleled together and communicating, the emergency stop button connecting to the master will also signal the other connected inverters to shutdown as well. If inverters are not paralleled, then each inverter would need its own emergency stop...

Interesting...then the installer base are gouging with mark up. Can we buy and DIY?

Hi again, I am seeking some clarification on design / install configuration for a 14kw PV with hybrid inverter and 30kwh battery storage. I have a Cutler hammer HP404040SH with max rating of 400amps (pic below). It has a 200A service breaker "A" with main breaker panel that provides service to...

I am not looking to go off grid....grid tied with only about 50% of needs generated via PV. So inverter is a distribution hub. Using batteries to reduce peak consumption by approx 7kw in every hour of peak rate. Failure modes of inverter is key...i.e. in event of trip does the unit continue to...

where did you price the powerwall 3?

Hi there, Sorry you received no responses. I am just starting my journey around the exact same goal. In AZ but on APS. Wanting a solar design to cut bill by 50% and as much as possible eliminate peak demand grid usage. Did you finalize a design? Would love to know where you are with this. Thanks

awesome...can you provide here?

Hi there, Sorry you received no responses. I am just starting my journey around the exact same goal. In AZ but on APS. Wanting a solar design to cut bill by 50% and as much as possible eliminate peak demand grid usage. Did you establish optimum direction? Would love to know where you are with...

Just had a quote for a PW3 system, yes LiPo batteries and acting like tesla invented it!!!...3 times the price of a solark / EG4 based system and are not nearly as functional e.g. discharge options, fail over conditions etc.

mandatory install so $12.5k each...not even close to solark/EG4

Does it seamlessly release current while simultaneously drawing from the grid? During peak I would be wanting to release up to 6kwh while drawing the excess load from the grid. Thanks

Feedback to the forum. This is the Sol Ark response (less than 24 hours after emailing them. Not heard from SS yet nor from utility company Thank you for reaching out to us. If you are wanting whole home backup on a 400A service, you need two 15K inverters to accommodate 400A of pass-through...

27kw Tesla PW3 with 12kw solar panels for $77.5k EG4 18kpv / EG 4 30kw battery rack with 15kw solar panels for $21k, 2k for racking, plus $5k for licensed electrician to install plus my labor to prep. OR add $2k for going SolArk. No brainer...better feature set, more upgradeable, more...

So you have to manually switch to grid supply? So if i am away then power stays off?

Thanks...Your equipment looks very similar to my design. Solarever panels? Why 60kwh of battery? Anything you would do different? Thanks
