Hi all, I have a problem with my new B230 and 2nd D050s.
The two D050s connected (one each) to my AC200Max and B230 each work fine when using one or the other, but the AC200Max faults 008 (over current) when trying to charge from both simultaneously.
Longer version with background and validation steps:
First, I have used my AC200 with a solar array connected to the PV input, and my first D050s charging the 2nd AC input from a 48v SLA battery (which has its own solar array) for a year now, and it has worked great (the 2nd slowly charges the SLA all week, and then I can draw on it day or night for weekend events in my mobile workshop) It has been trouble free.
I recently decided I wanted to raise max input to the AC200Max, and so bought a B230 for the extra charger input it would provide as much as (actually more than) more battery capacity (though that it nice). I had this B230 connected to a 3rd solar array via a 2nd D050S and that works fine as well, proving I think, that both D050Ss are connected fine. It works, but it’s not a lot of extra charge rate just because of the relatively small 3rd array. Fine.
I have now upped that 3rd array a bit and instead of connecting it to the new B230 directly via the 2nd D050s, I am routing that array (which can go over 60v) to a Victron controller into my 48V SLA bank, and then that bank connects to the 2nd D050s and then to the B230.
Used alone, this works great, and I can charge the B230 at around 450w, just as I could previously charge the AC200Max at around 450w, day or night, via my big SLA bank. In theory, I should be able to charge the AC200max by day with 1) the main solar array, and 2) D050s #1 from the SLA and 3) D050s #2 from the SLA via the B230. And by night, when needed, just by 2) and 3)
But, while two D050s connected (one each) to my AC200Max and B230 each work fine when using one or the other, when trying to charge from both simultaneously, the AC200Max faults 008 (over current)
What could be causing this? Of what use is the charging port on the B230 if I can’t use it with a Bluetti supplied charger while having it connected to the AC200Max also charging from a Bluetti supplied charger?
This was my whole reason for buying the B230 and 2nd D050S.
It’s all very perplexing, as I have a year of validating one part of the system working perfectly, and a month of the 2nd system, but now DOA when using both.
If anyone can shed any light or share any ideas, I’m all ears.
