Come on guys! Well put together video but you are called The Solar (LAB)!!!! You gave us your opinion and a few things you done with it plus its ratings! But never showed any testing!. It is winter! You said no way to check it for cold weather rating, but There is laser temperature gun that you could check to see even if the heater came on after the weekend or try and have it out side. It would be nice to know if everything on this battery works properly! And rumours are that heater will not even come on unless there is PV input and if that is not the case, how much power will it take from the battery to keep it warm over night. Good video but could have been better. Maybe you could do another video with testing cold weather functionality!!
The only thing that I do not like about my WallMount Outdoor EG4 battery is that they put the display on the side of the unit. I have mine outside in a, slightly modified, regular metal storage cabinet and it is impossible to see the display. I wish that they would make a front panel that had the display on it, but the EG4 6000XP and outdoor battery is great! It got us through hurricane Milton with no issues and the grid power was down for 4 days. It saved us about $500+ of frozen food in the freezers. Enjoyed the video, I even subscribed.
Now it just needs a small inverter in the same form factor about 8” tall to plug into that Gridboss you have hanging on the wall. The 18K and Flexboss are crazy big if all you need to do is plug into the Gridboss. Also can you comment on Charging this battery with a Chargeverter while it is outputting power? It would be great if the output power was not limited to what the Chargeverter is currently delivering. Net is I would like to charge via a “private charging circuit” (e.g. 30A) that does not affect the battery output capacity (e.g. >30A).
You were talkng about using these inside. The UK rules about placement have recently changed. Due to the Fire Risk from Lithium Battrleries, they need to be placed outside but protected from the weather. The concern is that in the event of fire, they cannot be extinguished by conventional means plus the Offgas potential is potentially lethal. Making them a danger to residents and fire crews Personally, if you have the space a Nissan Leaf, a bidirectional Chademo Charger and a Heggar bidirectional Consumer Unit that supports Home Assistant is the best option.
Hey where does it day in the documentation you can parallel up to 64 together? I thought that was only the 100ah server rack ones. Best I saw in documentation (from signature solar) was 3 in parallel. 1:49 is where you state the communication and parallel capability
Please explain more, 8:30 talked about air compressor draw for 10-seconds. Did it kill the battery power or what? Was this running through an inverter?
I'm in L.A. county, and rarely get below freezing, but curious about derating or degradation when temps get to 115 F on many a summer day. How much loss of power and life should I factor in for 4 months of 100 degree days? I can provide shade from direct sun, but that's all.
Bro just left the car scene to talk about generators? No hate or anything but you literally left us with no explanation. A simple video would've been fine but nope we got ghosted essentially. I hope you're having fun with these vids and your new channel honestly, we all deserve happiness and if this is it for you good on you. Thank you for years of car content and going to car shows and talking to all of us. I'll miss you. Stay committed ✌️
I did mention what I was doing (sort of) in the end of the last video I published! I plan on coming back to that just for fun again, when I can enjoy it like I used to! I guess that’s why I never made a video.. because I thought I’d be back sooner. But I appreciate the support and positivity👊🏼 Hope to see you back over there one day soon!
Thank you for the review: One great thing about this battery is that it has the required UL listing (1973 and 9540A) which means less trouble getting the inspection to clear! I think this is probably just a little bit of luck that "most" 100 A-hr batteries happen to have 100 Amp BMS outputs... I think at 6:50 or so, you are talking about two different values: a 100 amp-hr battery, to simplify, is how much energy is "stored" in the battery at the rated voltage (ie it can supply 100 amps for 1 hour, or 1 amp for 100 hours) and has Nothing to do with the BMS output capability of 100Amps... those are two different things. Thus, the rating of 280 A-hrs for the EG4 has Nothing to do with the BMS capability of 200 Amps... and you might be a little lose on the terminology, ie it is not a 14 KW battery, it is a (if you are using the right number) a 14 kilo-watt-HOUR battery... which has Nothing to do with the continuous watt output that the battery's BMS can output. (Note: to convert A-hrs to kWh, multiply the total battery voltage x the Amp-hrs. So, if that EG4 happens to be 51.2v x 280 Amp-hr cells that equals 14,336 watt-hrs or 14kWh. Whereas the "Watts output capability" is a function of the BMS and Inverter and limited by the Amps and voltage of the battery. So, yes, at 51.2 volts and 200 amps it can theoretically output ~10,000 watts (via the battery) (subject to the BMS limits). But to be clear, the amount of storage in a battery is independent of the output capability of the BMS... ie two different values, tho we often see them matching for convenience, there are plenty of 100 A-hr batteries out there with 50A BMS or even 120A BMS... it just varies.
its just that server rack batteries are more scaleable. Like eg4 larger inverters need 2 of these, just my thoughts (think of the same equivalent in terms of Server rack batteries)
It is not a con that it's 200a! The point was - when a server rack says its 100ah, it usually outputs 100a as well. This is 280ah, but only outputs 200a. Some people may simply get confused is all!
hmm build my own LFP batteries for 45-50$/kwh wholesale. had one cell go bad because of shipping damage, got a cash refund and bought more batteries coz the price had come down so much since i bought. 250$/kwh for a drop in solution is pretty cheap though if you cant go the diy route. just have to compare roi. short roi can actually make up for lower quality cells, which are not really a thing. anyone trying to say that 280ah lifepo4 cells are automotive grade a or whatever must be talking about an ev ive never heard of. no ev's made for the last few years use 280ah cells. i think i got my money back on the cells at 93 days after delivery, which was technically after the cut off but theyre so bad about shipping tracking they just gave it to me.
Can someone point out why you need an outdoor rated battery other than a Florida lowland flooding issue? At which point I assume it would seep from the base anyway and fry.
I really don't understand this product. No way it's going to warm up batteries in really cold environments, especially without insulation. If it had insulation, it would need active cooling in summer, which is almost more of a problem. I wouldn't shill for these unless I actual tested these for extended length of time in real world COLD conditions. So much marketing...
There are electric heating pads on the cell packs, it can absolutely warm the cells up when it's cold outside. We use them for broadcast mountain tower sites so we have quite a few sitting in the snow right now working just fine

I’m glad you didn’t say “ points off for no light “ on this battery.

The indoor has heating as well. Just not weather protected.
Does the indoor have EMP protection?
@@dslgod how often do you have EMPs in your area?
@@artdre1881quite often actually 2X a month.

They should have an ordering option for shipping with a pre-attached permanent mount hand truck.
I see you teasing me with a grid boss review in the back ground. You monster.
When you say that, it’s a 14 kW battery but only 10 kW of output, does that mean it can only hold a 10 kW charge?
I have indoor wall mounted, can I parallel it with server rack battery? I could. Or get an answer from SS

If you’re designing or installing a system with these, I don’t think you will get confused by 280Ah and 200A

The indoor version includes heating... Two batteries gives you 400 amps.
look at them biceps. o.0

I'm confused. How is the battery outputting 200a continuous a con? 10kwh ffs. Nobody is buying these to run them down in 1hr!

Where can one find the cells for DIY. $50 a kWh is pretty appealing.
@@Mentor_Imroo ali xp. cant share links on here.

We use 80 volt batteries at work in equipment and they heat themselves.
At -25 they used 25% of there power per day just heating themselves.
Based marketing video😂
Well compare it to DIY its way way more expensive.
It’s great for someone who has way to much money and zero experience in solar 😂
