The unmarked units are intriguing to me as I am not going to grid - tie them However, you would think they would be marked down a bit more than the pre-order marked units... ![Unsure :unsure: :unsure:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Another option is to mount the Solark 15k outdoors next to the batteries and just run longer AC wires?Depends on how much money you want to spend on wiring, and what is an acceptable voltage drop for you
That would be smarter, and less costly in wiring.Another option is to mount the Solark 15k outdoors next to the batteries and just run longer AC wires?
This is a concern I have as well. The EG4 Lifepower4's range is 33⁰F to 137⁰F. However, EG4 6500EX inverters decrease their abilities at 105⁰ F IIRC.@SignatureSolarJames
I know the spec sheets list some pretty high temperatures for ambient.. but..
My power meter and meter box are on the south side of my house and are hit with the full unshaded sun almost all day long. Can the 18kpv and these batteries stand up to full sunlight in 105-110 degree Texas sun? I assume that your company, being in Texas, have tested them under these exact conditions and found them to work flawlessly, but your personal assurance would be cool.
I'm considering building some sort of shaded enclosure with fans on that side of my house, but these darn HOA's don't like nothing.
All weather only if you live in the south. That baby would freeze up solid outside where I am.
Just watched Will's video on this battery and although it's pricier per kWh than a DIY build the footprint and ability to place it outdoors is REALLY tempting especially in a smaller home where space is already limited.
So using 4 parallel kits for 5p as shown in my attached cartoon would be a no-go?You absolutely can have more than 3, the parallel kit should only go 3 deep before you start using bus bars
A battery pack can be located a long distance away, you will just need to have larger diameter wires the further away. You always want as low of resistance in the wires as practical, the lower the better. The resistance of the wire causes a power loss proportional to the square of the current. With large enough wire, you can locate it as far away as you want. Look up the DC resistance of your available wire sizes. Wires can always be paralleled if you need lower resistance.Since this can be hung on an exterior wall, it raises some intriguing options. How far could I practically locate it? 20feet?
Just need to protect it with some of my Human Glue BoardsYeah make it really easy for thieves to take it, they won't even have to break in. No way I would put something like this outside. No Way!
@SignatureSolarJames I've been thinking about this some more, would the attached picture show a better 5p configuration? I just don't know if the EG4 18kPV needs to be connected to a single battery pack or not; you mentioned needing bus bars, etc. for > 3p, so I assume no? Just trying to understand what you envisioned/recommend for a 5P configuration with a single 18kPV?So using 4 parallel kits for 5p as shown in my attached cartoon would be a no-go?
Maybe add an extra parallel kit between each end battery and intermediate battery?
the 5P approach you have is fine, the total max draw is only 50A/Battery@SignatureSolarJames I've been thinking about this some more, would the attached picture show a better 5p configuration?

This layout could accommodate doubling the parallel kits between the batteries as well, would there be any benefit to that?
I'd like to use the pre-made parallel kit connections and leads and minimize the need for additional equipment/work/costs as much as possible; saving install effort, being plug and play, and the 10 year warranty makes an attractive bundle.
I'm currently planning my system and was going to build my batteries because the lifepro4 server rack batteries just weren't quite what I wanted; apparently I wasn't the only one thinking this because the powerpro announcement last week forced me back to the drawing board on my utility room layout, and has made the decision to build vs. buy much harder ?.
3 deep either way, 5 totalSo using 4 parallel kits for 5p as shown in my attached cartoon would be a no-go?

Isn't this rebrand of same battery GSL has. https://cdnsolar.ca/products/gsl-en...40a-ul1973-ce-emc-51-2v-280ah-lifepo4-lithiumWow.

And in case you missed Will Prowse’s videos on this battery:
So… $7k Canadian is $5186 US (today).Isn't this rebrand of same battery GSL has. https://cdnsolar.ca/products/gsl-en...40a-ul1973-ce-emc-51-2v-280ah-lifepo4-lithium
Can get it Canada for 7K in some stores, self-heated as well. However GSL can parallel up to 16. This one is limited to 3.
There is also 7% duty on imports to canada.So… $7k Canadian is $5186 US (today).
The Signature Solar battery is $4000 US +shipping.
Not sure how that works out.
But if you need to put more than three together, awesome, go for it. ????
It seems both use internal busbars. Question is why EG4 one has the limit of 3 in parallel per inverter.There is also 7% duty on imports to canada.
Yeah, I figured there was but I was not sure of the number on that.There is also 7% duty on imports to canada.
EG4 also added fire arrestors, which is a nice feature.Yeah, I figured there was but I was not sure of the number on that.
At the school I went to
7% of 4000 is 280.
So 4280 plus shipping yeah maybe that’s not worth it for Canada.
Good point. I am curious about the 3 limit vs 16. Not that I’d ever need more than 3.EG4 also added fire arrestors, which is a nice feature.
it is up to 16, we are saying to not daisy chain the bus bars more than 3 deepIsn't this rebrand of same battery GSL has. https://cdnsolar.ca/products/gsl-en...40a-ul1973-ce-emc-51-2v-280ah-lifepo4-lithium

ok yeah I actually spoke to GSL, they recommend external busbar for more batteries in parallel, so same thingit is up to 16, we are saying to not daisy chain the bus bars more than 3 deep
A car is easier to both steal and fence/strip for parts, and is frequently located right on the street. A 300 pound box mounted to the side of the house and/or bolted to a concrete pad, connected to a live inverter is not exactly a smash & grab target any more than an air conditioner condenser.Yeah make it really easy for thieves to take it, they won't even have to break in.

@SignatureSolarJames, will the 9540 cert in September only cover the combination with an EG4 inverter (presumably the 18k)? Or will it cover any other inverter combinations?9540A now 9540 by September, CEC by October
