Thank you for these words of wisdom.

If you look 'UL Source' column in the spreadsheet I posted you should notice that the UL source for all 4 of the lowest cost$/kWhours are NOT the California's website... I don't know the processes/procedures to get that site updated nor how long of a lag any updates may have... Also please be...

Our current house is in North Texas and we have ranged from approx -2 to 112 outside the lowest I have seen inside is around 20 degrees & the hottest around 100. The corner of my garage where the electrical panels is right by the garage door which currently is not insulated & is basically just...

Edit: I ordered and have here in my office one of the '50 Amp A510C Pro/Tran 2 Transfer Switches' just so I could study it and make sure it would work as I was hoping. I am very pleased with it and plan to get another if we pull the trigger with a full solar implementation on our new roof. We...

Thanks so much for sharing. Until the industry gets to the point that V2H (at least for emergencies) is standard & seamless it is great that we have folks like you taking the time to document your solutions...

If I pursued something like this I likely would be doing it with a somewhat older one off lease/warranty. Personally I wouldn't be planning on making powering my home from my vehicle battery a part of my daily routine (unless the vehicle was designed for that) but I would definitely like a safe...

Intrigued. Having extra battery storage in an emergency could be priceless... To me the primary reason for any energy storage at home is for the safety of my family and any possible economic benefit/dynamic is "just gravy"... I read some of your Vanabolt posts/threads... While intriguing...

As discussed in this post & subsequent replies: "I am not a solar expert but did my best to review the Spec Sheet & the User Guide & it to me it looks like it supports / recommends: 190A Charging/Discharging DC Current with Batteries (with 200A breaker); 33.3A Nominal AC Current Output to Grid...

That would be great to confirm & know for sure whether the Grid line to the inverter is bi-directional. I am not an expert on this stuff & was assuming that Load2 was back to the main panel. If the grid line is bidirectional & the Load2 goes down when the grid is down then I am not sure what...

I am not an expert but conceptually to me the big advantage is that the EG4-8KEXP-240 can be Grid Tied such that excess Solar could be fed out to the grid & thus use the utility company "like a battery" for any excess power generated from Solar... If your 12KW of PV produced extra energy during...

I am not a solar expert but did my best to review the Spec Sheet & the User Guide & it to me it looks like it supports / recommends: 190A Charging/Discharging DC Current with Batteries (with 200A breaker); 33.3A Nominal AC Current Output to Grid (with 40A breaker); 36.7A Maximum AC Current...

Has anyone bought these batteries from here (currently they are $1,200 USD) ? : https://www.globalsources.com/LiFePO4-battery/Solar-Battery-1190910609p.htm What countries have you had them shipped to and how expensive was the shipping ?

Is SUB short for providing power to loads priority-wise first from Solar, then Utility, then Battery? If you have grid power & set SUB & the sun goes down does the inverter switch to just bypass mode to provide power from Utility only and shut down the inverter & thus have less Watts...

The report for SOK's UL 1973 certification for their cost effective 48 Volt (51.2 Nominal) 100Ah, 5.12 kWh server rack battery has been released in draft form. Final version expected this month (October 2022). The report & ETA are discussed in the web based owner's manual on page 1-4...

I could be wrong but you may be able to keep your grid power & house circuits in your main panel & just add 2 outbound circuits from your main panel into the two EG4 6500s and then feed the EG4 6500s outputs to one or more Transfer Switches (instead of moving all your circuits to a sub-panel)...

Our current home has two 200 Amp main panels fed from grid. I am considering doing an "off-grid" setup based on Will's 'Complete DIY 48V Offgrid Solar Power System' design here: https://www.mobile-solarpower.com/48v-complete-system-blueprint.html Some deviations I plan: -Want grid AC fed into...

I was thinking of buying 2+ LVX6048WPs. In reading this thread it seemed a mix of both LVX6048WP & LVX6048 so a little confused. Is the LVX6048WP a high frequency or low frequency inverter? Does the LVX6048WP have the roughly the same idle draw as the LVX6048 (~135W each)? Anyone have a...

What needs to be discussed? Why would a bolted configuration in a protective metal roll cage that allows self-repair down the line be a worse approach?

Thanks again for all the good info. Hopefully Emporium ends up providing a way that the system can be monitored/maintained in a true internet down or even worse full grid down situation. I really like that https://www.iotawatt.com/ is fully Open Source so the community can verify no...

Thanks for the info. Can you tell whether it is a locally hosted web interface on the Emporia Energy Monitor itself or do you have to connect to an externally "cloud" hosted Emporia web interface to get the CSV file?

Thanks @fafrd for all the informative posts & please let us know if you see their Energy Storage System (ESS) &/or bi-directional charger (V2X) actually become available. I am very interested & am planning on starting a home build later this year & an ideal setup for me would be an ESS with a...

Not all EV cycling would be un-necessary in all scenarios... Personally I would love to have an EV (or PHEV with a large battery) be easily and safely available to my home in a grid down scenario. Personally I like to have grid to my home and try to have enough hybrid inverter + battery...

I am pretty sure awhile back I saw both this V2X potential offering & also their POTENTIAL Energy Storage System (ESS) offering: https://www.emporiaenergy.com/home-battery The problem with both of the above is those are POTENTIAL offerings... Like pretty much everything else I have seen lots...

Progress-wise we first cleared that garage corner by taking down shelving & taking down mounted bike racks, mounted Fibre Optic termination point for the house (that was currently not in use as we temporarily switched to Cable Modem), & rerouted garage door opener wires/etc... We also mounted...

Is your solution automated and if so how is it triggered to start & stop?

Isn't faster top-end wear only an issue with some dual-fuel generators & not an issue on LP only generators?

The smallest I have seen reported to work reliably in an automated fashion with the Sol-Ark is the 8.5kW Champion Generator: https://diysolarforum.com/threads/need-your-advice-on-best-dual-fuel-generator-for-12k-sol-ark.34795/page-2#post-438711 They make larger as well if you really do need...

Congrats! Yeah we also were hitting 105 here and our central ACs were not keeping up so I bit the bullet and put in 2 15 CEER 12K BTU AC units for supplemental & emergency cooling: https://www.midea.com/us/air-conditioners/window-air-conditioners/12000-btu-u-shaped-air-conditioner-maw12v1qwt...

Cool and congrats! Have you already tested (or do you soon plan to test it) with a Sol-Ark?

In recent comments it was denoted that "...At 14:30 it was clearly drawing 150 amps from the battery...". Don't know if that fully answers the question of whether it was properly configured nor what firmware version the system was running.

In reading the comments to that video it was never answered, even though it was asked multiple times whether for the Sol-Ark if "...the setting for this test was done with [default] 100a or [with] the changed setting of 185a..."? If the settings were incorrect likely it would be more fair to...

I would check the manuals and the Sol-Ark website. In addition there was some discussion in this thread: https://diysolarforum.com/threads/sol-ark-12k-with-small-generator.31716/

Added EG4's LifePower4 Lithium Battery | 48V 100AH to the spreadsheet linked at the top. UL announcement: https://signaturesolar.com/solar-news/eg4-announces-battery-ul-listing/ UL 1973 Certificate: https://signaturesolar.com/content/documents/EG4/1511006-ul.pdf Battery link...

Overall I agree and would not want to do it as a regular every day solution. If I recall correctly I think James has/had both an older RAV4EV (pure battery) and the newer Rav4 Prime PHEV (plugin hybrid) and that most recent testing video was with the Prime PHEV. That being said, in an extended...

Interesting workaround & thanks for sharing. If I understand correctly in this video James Klafehn thought his testing was getting between 82 - 113 amps out of the DC-to-DC converter from the high voltage EV battery to his 12V battery sub-system (discussed throughout and particularly at 9:54...
