I'm chasing another problem with this system, that I haven't been able to pin down. I'll give you a short amount of background, in case it's relevant.
The system originally was 2 quattros in parallel, 10 Victron Lithium batteries (300ah) and 8 100/30 mppts. I share this, because I observed in the previous setup before anything was removed...nearly 60amps charging and the owner at that time stated that it would get to 100 on a bright sunny day with no clouds.
As part of buying this boat, the previous owner took one of the quattros and 5 of the batteries. I have replaced that quattro since, so now the setup is
2 quattros in parallel (5000/12/220)
5 x 300ah Victron Lithium
8 mppts connecting about 3k in solar panels.
Here's where the issue comes in. In the middle of the day, when the sun is directly overhead, and I'm generating 1600 watts of soloar (as measured by the quattro on the cerbo screen) - I will barely reach 20amps charging, usually less. My idle draw is about 15 to 20 amps, but its always been that, so observing 60, means the production at that point was 75 to 80. Right now I'd expect 133 amps raw, before any loss or conversion or vodoo that happens between components. I think it's reasonable to guess while generating 1600 watts of solar, that I should see 100 amps (mins 15 to 20 idle)....Am I incorrect?
I know that the mppts will downscale, I've appropriatly measured the battery SOC so they should bulk, measured the temp so there are no temp issues (unless there's some settings that arent correct), and I have access to all the MPPT's through the VRM for their settings if those need tracked down.
I also know how complicated all the settings can be between MPPT's, quattros, batteries...etc. So I'm looking for some help tracking it down. I can been the hammer, just need the person to wield the tool and get me there, or tell me it's working as intended.
Thanks in advance, I love this community and how everyone helps.
P.S - If there's a victron "expert" in the area of Caribbean Martinique (or you are available to fly in) I would absolutely love to talk to you.
