20kg battery + sparks on your nuts, hopefully you already have kids Big Grin
Current setup: 21x 215wc poly, 7.5kWh 7s 18650, PIP 2424msxe.

Yeap have 3 of em.. And no more will come Big Grin

Added the 2nd watchmon into the game.


2nd battery bank is not hooked up to main system as you can see with the battery voltage. The red indication on 4.10 and 4.18V indicates that the Watchmon is burning of the top voltage of the cells. This to get it down somewhat so i can run it in paralell.

So now i have 78 Longmons in use!

Is that dashboard part of the Batrium software? Or is that a separate piece of software?

That is Grafana and a dashboard that i have put together. Data is partly taken from Batrium in here.

Doing some work on it and there will most likely be some templates and such available for people that want to incorporate it with Batrium or for that matter any other software or hardware.

Grafana is a graphing tool that is free. I run it on Linux server on top of graphite and some other stuff. Going to create some kind of ISO for it so people easily can get it going.

Nice dashboard. Are the 2 Batriums linked in any way or completely independent?

Also just watched your video with the leaky cell, one thing I would suggest to avoid that is not using cells below 70-80% of the original capacity, particularly in things that are gonna get considerable cycles like power tools, any motorized stuff basically. You could easily double years of cycles on a laptop cell in a few months.

2 different batrium systems. Only thing in common is that the batteries monitored are hooked up to same equipment (Not yet though)

I would say the other way around Smile For stuff like that cheap ATV for kids its a perfect place to use the lower end cells. I rather have them in that environment where i can controll the discharge and charge where I am around than in a powerwall Smile

I would not use any lower end cells in any high end equipment or function though.

Yeah I wasn't suggesting using them actively in anything, I'm using them to make spare packs in case my active ones need maintenance, a few hours of use maybe. My only point is you'll get longer, consistent use from a cell that tests 1800 and was 2000 originally vs a cell that tests 2000-2100 and was 2600-2800 originally. That's just from the testing I've done on cells from packs where I knew the cycles. The originally higher capacity cells drop below the lower capacity cells in 60-80 cycles

Some stats for last month:
Solar produced: 1628kWh
Bought from grid: 247kWh (Out of those i had 50kwh due to doing a testcharge of the bank)
Sold to grid: 453kWh

Total power saved and used from battery: 462kWh
Total charged: 485kWh

So why did I charge 23kWh more to the battery bank than using? First of all you have some losses as always when charging. its not 1-1. LiFe is close to 100%. But lets say 99%.

So we still have alot of losses.. No we dont (I Think) The reason is that i have done alof of balancing lately due to not all being in balance and therefore it differs.

I just quickly looked it through but it looks like one of the better documents that describes the differences of the types.

Yep - that's the one i clicked on after browsing which ones were available.

I guess it's all about the concept of low cost power- we have paid so much for for our power needs for so long that the idea of a low cost energy source is compelling.

Batteries are nice, panels are sexy !

Update 2017-06-04


Im now running 46 panels in total at 260Wp each. ~12kW.  And Im working on adding another 18 to the east roof of my garage.

Editing video of adding/moving 2 of them and will be up later tonight.

I also have 6 panels to South at 80 degree angle just leaning towards the wall. Merely for testing but at same time its all about utilizing all space you got available.


I still need bunch of angle irons and other stuff to be able to mount last 18 panels on the roof.

Video + images will come later on how it look now. Currently its raining here and dark sky. Still producing 1400w ouf ot 12000 possible. So almost 12% of max. 

So im currently discharging battery bank but thats no problem.
