Abusing free nights electricity plan with batteries

Was looking to build out my existing back up battery bank and possibly add solar down the road. Looking at plans I came across this with Chariot Energy. This was for their free night plans which only run from 11pm to 6am.

Basically they only want EVs charged with the free power, which makes sense otherwise they are taking a bath when customer charges up house ess instead and offsets potential daytime grid consumption.
 
HUGE RED FLAG: "Chariot Energy reserves the right to charge Customer the highest energy charge rate applicable... without regard to such product's time-of-use terms, conditions, restrictions, or other provisions."

All these "products" are just selling the same thing, electricity. It's like what many companies used to do with mail in rebates. They make you jump through hoops so that you think that you might save a few bucks. They are the judge, jury, and executioner to decide if they will pay your rebate or deny it due to some loophole. Kinda like how insurance companies are today. They decide how much to charge you, what to cover when you need it, how much to pay you, and deny your coverage due to some loophole. With these electricity "products" they are just creating all these hoops that you have to jump through to try to outwit them and get a better price. When it's all said and done, it's just one product with dozens of gimmicks to get you to sign up for their multiple "products" of the same thing.

I've been using a Sol-Ark 15K and 3 EG4 Power Pro outdoor batteries with infuse Energy's free nights plan since July 2024, with no problems. My bill is regularly less than $20.00 per month for a 3,900 sf house. Adding bitcoin mining next. The inverter and batteries qualified for the 30% tax credit.

Here is what my daily usage looks like.

About to do this on a new home:
2x LG Prime 16h batteries (Signature Solar deal) and 1x Solis S6 11.4kw, this will integrate into my new house where I am installing a Gridboss +Flexboss system as well. figured I could make some content on both HV and LV system types

Hi James,

Looks like these are still using LG NCM cells and not LFP?

Definitely an outdoors install maybe attached to a concrete outbuilding, fire seems inevitable at some point like the recalled previous generation?

I'm using LG RESU-10H with SMA Sunny Boy Storage.

The anticipated cycle life is about half what some LiFePO4 batteries list, increasing cost per kWh of cycle life.

I had been seeing 9.2 kWh reported from fully charged to shutdown. Then it dropped to 7.5 kWh (suddenly?) and is stable there.
The kWh of charge is considerably higher than discharge, showing 20% or so power loss in a cycle.

They do work, but seem less attractive that LiFePO4.
 
I could have sworn at least one of the two RESU-10H I bought was on the recall list. Should have saved screenshots. My plan when I bought them unused from an e-waste place was to get them replaced. Turned out one is for StorEdge and I can't use it. The one I am using, for Sunny Boy Storage, now shows up as not on the recall.

Remember when the Bolt recall went from "We will spend $2B to replace all batteries" to "We will monitor your battery closely and tell you if it needs to be replaced"? The "On recall list" lookup moved from U.S. to Korea, I think, and bean counters may have weighed in on the program.

Yes, they are outside, hanging on a cinderblock retaining wall at edge of driveway. If they do go up the house is unaffected, and I'll then ask LG for replacements.

they are the gen3, over 100k in the field with no recal. the RESU 2 was the issue, not the Prime

Wow, that's quite a few. But only 2/3 as many as Chevy Bolt sold since 2017. I would think ESS gets non-EV-grade batteries rejected at test. Well, maybe that's in line with reasonable reject rate, considering Wh capacity of the packs in each.

 
I own a Chevy Bolt EUV and park and charge inside my garage. After seeing the LG Prime 16H on sale at Signature Solar, I'm seriously considering some as cost per kwh (capacity) is cheaper than the EG4 wall mount battery. However cycle life will never match. It is a much cheaper cost since I already have an existing SolarEdge system and can add these batteries without the need of a second inverter.

Having these batteries inside my garage shouldn't be much different than having my bolt EUV inside my garage (says the non-expert) :LOL:
 
EV grade batteries worked hard, or EV-reject batteries babied? Which will go up in flames first?

"Las Vegas", a gambler, Huh?
You'll now be playing Russian Roulette with two rounds not just one.

They do come in an outdoor package. Instructions probably call for roof to prevent direct sun and rain, mine did.

The lg prime 16h is a high voltage battery. Sig solar are doing bundles with Solis hv inverters. Its not compatible with 48V systems.

Wonder if they have any relation to the 1200MWh of lg cells that went up at Moss landing.

Sorry Texas people I was thinking about doing this next month when we move to a new house that doesnt have solar, I may be the straw that breaks the camels back on free nights like half the members think will happen.

What is the easiest way? I like the EcoFlow Delta Pro Ultra but the panel only has 12 slots... do I need a smart panel to take advantage of TOU?
There is another member in DFW selling a 21kw Delta Pro 3 set up I was thinking off picking up but it looks like I can get a 4 stack of Ultras with the inverter and panel for about 1k more after the 30% rebate.

Was thinking to possibly only do the ~20 so the big dog still gets its food and eventually after 9 years it pays for itself and I have a back up option for our yearly winter storm.

I don't want to put panels on the house since it has a metal roof, but there are two shops/sheds/carport nearby I wouldn't mind putting panels on and possibly the barn but that is further out, it does have power running to it so maybe there is a way?

Lots of options there, high voltage runs for PV from the barn shouldn’t be a problem.

Personally, I’d put a ground mount to the left of the pool.

There are mounts that clamp to standing seams and hold rails for panels. No penetrations.
But I would think how wind resistant they are depends on how secure metal roof is under those clamps.

Or maybe that is rail-less mounts:

 
Just a warning to anyone considering free nights in Texas from Direct Energy, it seems that they removed solar buyback on these plans. I just cut over on March 16th and have been surprised to see no solar credits at all. Got my first bill and same thing. Call to customer service said no buyback.

Had asked multiple people who discussed these plans on here and all confirmed they had buyback, just at a rate of .03¢/kwh. So this is a super recent change.

16.2kw solar
93kwh batteries

... So now what am I going to do with my excess? Maybe I'll take up crypto mining or something. I've got like a 6-8kw excess at basically any time during the day and free at night.

why did you go with direct energy over just energy?
