Well, what are you waiting for!?! Rip into them!!! ;)
 
Sounds good to me. 14s gives you the best options for wiring. Though, the inverters are a bit limited for the US market. That is, UL-listed and certified. Plenty of Chinese inverters that will work, they just aren't certified. Which may not be a problem.
The larger the pack, the more each pack can store. However, that kinda dictates what you want to build.
 
That's right! Hell of a deal. Any tips? These little tabs are slicing the hell out of my fingers. I need to be more careful
 
Get a pair of small snips and cut the tabs first before trying to pull them apart. And actually, several others just snipped off as much of the tab as possible and left the welded portion on the cell. Some of the welds can be so tight that they actually rip a hole in the Neg side of the cell.
 
I have an icharger 106b+ should i charge each one of these up individually or can i buy/build a cradle to balance charge multiple cells like a lipo?

also, can i rename this thread? since its linked to my profile i should probably give it a name
 
You can rename it.

You can parallel many cells on came and charge. Balance charge them generally takes longer time. So if you have tons of cells at same voltage just parallel charge them all if they are from same batch. Then you can do the discharge test one by one afterwards.
 
Thanks! Been watching your transfer switch contactor videos.. would that transfer fast enough to keep most things on? Or do you find your appliances blinking 12:00 very often?
 
They would switch fast enough but there might be issues... There will be coming a 3rd video. An issue would be if it switches between sources not synced. Then you might get a spike to the load.

Note that the switching there is kind of the same as many inverters like the PIP do. The PIP though switch a bit faster i think. Might test that too if i got time :)
 
These deep purple cells are nice looking.

Does batrium have digital outputs that can be programmed to energize relays or contactors based off different parameters? Cell voltages or schedules, etc?

Just thinking ahead if I can't find a US hybrid inverter to do some switching. (Which I hope I'll be able to)

So, umm, that hammer is there to persuade the shrink wrap to come off? :p

Nice batch!
 
Yes. Batrium does have output latches and you can do alot with that. With the expansion board you have a couple of relays on it.

Im on wrong computer to screenshoot how it looks.
 
Hmm, interesting. What's the price point? You looking at the 4048 model?

Yeah 4048 looks like 4kw/48v system

looks like they are between 1500-1750

some cool features, and some nice accessories as well.

Mayson,
Take a look at thisinverter. It's the one I'm most likely going to use for my set up (just need to convince the wife). 12KW UL approved for 1900 usd.

I did come across that one in my search. I think the marketing of the schneider is very good.. i am intrigued by their marketing terms..

Peak Load Shaving:Conext XW+ and SW can limit the power draw from the utility connection by adding power above a set point to support large temporary loads, helping avoid peak usage charges in areas with tier-based tariff on capacity of incoming feed or on peak consumption.

Grid Boosting:Conext XW+ and SW can supplement grid input with extra AC power to support large loads, temporarily boosting power within a home beyond the limit of the grid connection.

  • Prioritize consumption of solar power ahead of utility power withPriorityPower
  • Avoid utility peak charges withParallelPower
  • Temporarily increase power within the home withParallelPower
  • Take advantage of the lower lifetime cost of Lithium Ion batteries withChargePowertechnology
  • Sell power to the utility withGridSell(Conext XW+)

this piece looks fun too:https://solar.schneider-electric.com/product/conext-combox/
even though i will have batrium and maybe even the grafana setup ive seen.

and their components are modular and snap together like lego peices.. how sexy is this:
