Hmm I had a good experience with them and the cells shipped were flawless so far

Hey just wanted to say I purchased 34 lf280k V3. 3 JK BMS. And other things it's been a great experience so far. This is the second time I've ordered from them and they've both been good experiences. And I have to order cross border so that adds to complexity. Video of the cells here.

These are my thoughts as well. Old stock will get chewed up then prices will skyrocket.

Does it automatically restart, or does it have to be manually restart after error? Could be problematic in an unsupervised remote off grid location.

Fantastic news!!

Fantastic news! what was the one fault? I have the same inverter but its only being used a charger right now.

I checked with SRNE, they had this to say: Parallel 10KW will be come out soon, may next month I told them once they have I want to test the capabilities of it and make a video so i'd order qty 2 units

Hey All Other than the fact that running 120V from inverter is less efficient than running direct from battery.... what are the thoughts on this style heater underneath a 1/4" aluminum plate that would be under all the batteries in an insulated box...

I believe the reason they do this is because the current drops off when approaching full, so you'd be wasting fuel from your generator not running at optimal loading. Smart in my opinion, if your trying to get it to hit float so you can balance cells or something, run a separate charger from...

Don't forget to update the thread with your findings, is that a 12k or a 15k?

Deleted, OP answered question in his post.

I'll call signature solar tomorrow and ask the questions

I think best bet is full shut down when leaving including power off batteries. Then upon arrival. Start generator and heat up the building via woodstove and electric heater in the battery room till they warm up then proceed to use batteries as normal. They are in the heated space when using the...

Is anyone in this thread thinking long term? There will be a glut of cells now and then prices will sky rocket as they get either old or there is less production?

You put the power pro batteries in an insulated box or diy cells?

My question is how much power do the heaters use? Use case: off grid cabin. Powered off when not in use. But when arriving at the cabin it's -40F. Will the heaters heat to above freezing then let the batteries take charge? Or will the room need to be preheated externally first. Propane burner...

This is interesting I never thought of hearing sand to use as a heat battery

more and more insurance companies are finding ways to get out of claims, they are not really as helpful as they once were.... That said, 3 feet doesn't seem too unrealistic to separate the battery packs?

100%! Is there an efficiency chart for inverters? showing what the efficiency is at given loads? That would be a smart piece of insight!

Sorry I should rephrase that, I am more interested in the efficiency of the inverter whether charging or discharging, how much of the incoming power is making it to the finish line, end use point. In my particular use case idle consumption of either 60w or 90w is negligible compared to the...

idle consumption statistics are useless to me. I live off grid, my inverter is never sitting "idle". I have seen my solark 15k inverter eating as much as 500 watts when its inverting about 5000 watts to the house, charging with whats left, and pulling in 10k from solar. but so far its reliable!

What is your pack voltage when the state of charge causes it to pull from grid? I only use battery voltage on my solark 15k, I don't use communications, frankly i don't like the complexity of communications, let the BMS do its job instead of the inverter do the bms's job, if your packs are...

I ended up getting a SRNE 10kw split phase for this job. It's mint!

SRNE 10kw split phase, will be all you need ever going forward, and very affordable on alibaba! I have one as a backup

Sunark is not solark guaranteed. Just a play on words

I just started to not use generator. We've had November gloom in February this year! Some other things you can do to abuse your power. Dehumidify a garage where you park winter vehicles. AC that garage in summer Put an electric patio heater load outside in winter Generate multiple tanks of...

Only when its cold Today its cloudy and sunny mixture so I am getting those spikes throughout the day. But if its full sun it will stay that way until the panels heat up. If its -30*C yes i've seen that sustained! But black panels heat up quick from the sun even if its freezing outside.

Attached is the record i've seen so far, this happening right now on my array taking in almost 12.5 kw on a 10.7 kw array!

And I always like.the stacking factor on these better for space saving! Dang you cost me some money hahaha

Agreed! I think I might have to look into these strictly because they are premade and save me hours of time on a diy pack, even though I LOVE my DIY packs!

Has Anyone ever ordered directly from these guys before that is a really good price!

Where are these cells found? that is dirt cheap!

That's a pretty good price! Considering when I do quick math for the batteries from china, plus shipping, plus odds and ends that are needed its around $125/ kwh give or take.

Prices seem pretty fair these days! Bulk meaning 120-160 cells as they ship 4/ per wooden crate. I prefer to move things with forklifts.

Are there any new hoops and hurdles with importing bulk cells into North America?
