(2) 100/50 controllers networked with smart shunt. Works fine for days/weeks then 1 controller fails to start causing me to lose solar production entire day on that array unless I am there to catch it. This doesn't occur when it isn't networked. Same thing used to happen on my other (3) thirty amp controllers until the 2 offending controllers were replaced. Knock on wood still functioning.
Luckily both these 100/50 controllers were replaced under warranty, because 1 started acting up was replaced then other acted up shortly after. I got a month no issues now 1 unit is randomly not starting. While I appreciate warranty this is huge hassel. For me it will be total of 5 units if I pursue this current issue. I have taken them out of network for now and they both function fine but battery bank does not have low temperature protect for me that was purpose of shunt.
