I have often wondered exactly what is inside of these prismatic cells? To me, it seems a lot of money is spent on packaging sheets and terminals, which real cell parts storing energy (anode, separator, cathode) could a lot cheaper.
Has anyone ever opened up a prismatic cell to see exactly what...
I have been looking for BMS that can be communicated directly with Sol-Ark Inverters. So far the only one I heard that might work are Orion BMS.
Has anyone gotten Orion BMS to work with Sol-Ark Inverters?
Or anyone confirmed any other BMS that communicate well with Sol-Ark Inverters?
Thanks...
So, I currently have both a Sol-Ark and an Outback Radian GS8048a.
Currently, I actually have Sol-Ark 12K up and running with battery backup, but not 100% satisfied with its performance.
As for my Outback Radian, GS8048a it seemed more complex and hard setup with MATE3S controller. I had...
Hello,
I am thinking about would be the easiest way to compress 16S (~300ah) cells?
Seems like everyone is using thread rods and springs. Is that easiest to apply compression to keep the battery cells from moving?
Any other simple solution instead of having to build a compression structure...
I plan to put a bank of 100-200 cells outdoor in a large metal waterproof box. Are there any issues with the LIFEPO4 that require venting? can I put in a Water/Airtight configuration?
I need figure out whether I need plan put vents on the box holding the batteries or not.
Thanks
Hello,
There are couple of inverters that take high voltage 250V to 500V DC batteries. Are there any BMS that can handle that many cells in series that can be bought?
Also, can you put multiple BMS in series? For example take a BMS that supports 16S (48V) and put 5 of them in series for 250V...
I have a JBD-AP21S001(150A) BMS that seems to require a wried short circuit for a 16S config. This one has B0 to B21 wires; see below.
The last six wires are shorted together on the 2nd to the last cell. I tried a few configurations of shorting, but the BT app still shows at least 17 cells. I...
Hello,
Has anyone gotten Time of Use (Battery Charging from AC Grid at night) to work on these inverters?
I have put the setting to charge at night from Grid but doesn't seem to do anything at all.Thanks
Hello, are there any competitors that make micro inverter expect Enphase and APsystem UL Listed for USA?
I think there Chinese Daforn or Ging but don't seem to able to find them. Possibly it seems like the above 2 are main options for Micro-Inverters?
Hello, I have the following 304ah EVE cells. Does anyone know where I can find a spreadsheet that tells me the voltage for each percentage point?
I want to get as accurate as possible so 101 entries from 100, 99, 98, etc to 0.
Thanks
I have a off-Grid Sol-Ark 12K setup currently. Its looked up right now with Battery, PV, and Gen as backup. The PV is already maxed out at 13 kW. There is no Grid (no grid input being used).
I was thinking about using another 240V (L-N, not split phase) inverter (low cost ones) to feed the...
Hey Brett,
I love your enclosure! Did you just pick them up from a hardware store and what are the dimensions?
I am thinking about whether I can also put in 16S in such an enclosure.
I am looking into another set of inverters to try for my next project. I was thinking about buying Voltronic clone inverter like MPP Solar/Pow Mr (or even import from China). They have stacking/Parallel support so I am thinking of getting 3-5 of them and Parallel that to an AutoTransformer (to...
