Hi folks,
I just found something else I don’t know… And although I am 100% confident that there is much more that I don’t know, I don’t know, I would like to pin down this one thing, for now, if anyone can help.
This came up in another thread, and I realised I didn’t have a good answer, in fact no answer, once I considered it properly.
It would have been off topic, and or thread hijacking, to ask this specific question there.
I use DVCC on one of my systems to manage charge current, the specifics are not important, there is only one energy source, AC in, and I only use DVCC because it allows me to set a charge current, easily and dynamically, not because anything needs sharing or distributing.
It works just fine in that limited application, although I am sure using it like that will garner some comment.
However my question is this…
On my other system,
Multiplus 48/5000,
SmartSolar on VE Direct port.
BYD 13.8 kW B-Box pro, Can connected.
CCGX.
With DVCC enabled, forced on by the BYD battery in this case, how would setting a charge current limit affect my two energy sources, AC In, a generator and a DC coupled SmartSolar charger.
Assuming that there was both AC and solar available and I applied a charge current limit using DVCC, would the two chargers back out by the same current / percentage, or would one of them be backed out first, favouring the other, solar presumably, were that to be case.
I can probably test this, if there isn’t a clear answer, but I am hoping that there will be an answer, and some rational to help me understand why it is the way it is… whatever that may be.
The issue with testing is scope, a single test may give me an answer in specific circumstances but I wouldn’t be sure that it always applied!
Thanks for looking,
Al
