I don't get it because JK to solis is one of the most common configs for these.

Fogstar are great.

I am not surprised you don't get it!!! 🤣 

Fogstar fan club members are not always obvious to spot, but you give it away! 

Just read the posts and learn about JK.

Batpred seems to be more interested in how badly Fogstar have treated them.

Easy to spot the second collaborator. 🤣 

So what is your interest in HA and Solis?

You're telling us about Instructions and firmware upgrades...
... whilst I'm writing about little red wires 🤨 

Without knowing what you've connected where ...

@transparent

 

The readings are 0 for amps, 0 for volts, etc (for the complete battery pack). The inverter does not read voltages for specific cells. We know that the JK balancer is the one reading voltages for each cell level. 

 

I assembled the battery kit following Fogstar's video instructions (and reached out to them multiple times, since the video did not match what they shipped). People that do this for a living would be aware of the differences between the video and the latest kit.   

 

 

At 14min:11sec, you can see the final connection to the JK. 

 

In summary, Fogstar designed the wiring from the JK to the cells including two boards. I can't remember if there are any active components in these boards. But anyway, each of these is connected to the JK via a busbar. So the wiring to the cells is from these boards. 

 

Coming back to the issue I am experiencing, it smells of comms. 

 

One challenge is that, unsurprisingly, Fogstar/Seplos are not a battery that Solis supports. Hopefully these issues will be solved soon.  

 

The reason I posted this here is so readers can make their own mind as to whether this battery assembling process is anything they would want to get involved in. 

 

One consequence of a DIY process is that, whenever there are problems, it is not possible to get Fogstar as the retailer to solve them with the engineers of the inverter of your choice.

 

The fact is that, if I bought a ready made battery, I would also have the advantage that solving issues with integration of the product with the inverter would be much simpler. And it would have cost less.
