Hi folks! I have a weird situation :) House is ~30 meters from garage. House has 1 system, garage will have 2, all of them will be grid-tied inverters ~5kwp. House also has batteries connected and obviously that's the main system (all 1 phase). I would like, during bad weather, to somehow...

Should be the other way around. So in case of partial shading, you're only producing 50% of the current, but 100% of the voltage.

Yep. New location, same equipment, but new wires and new MC4s between panels and inverter.

Canadian Solar 375 Wp, CS3L-375MS, PERC, HiKu They are the same 7 panels, connected in series. Previously there were organized in 1 row, now they are in 3/3/1 (will add 2 more panels soon) I've had them for longer, but they were part of a pair of strings on a different invertor, so I can't use...

Not sure if they are rated/approved for DC, I would not advise on using them. I used them as it was on a temporary setup and I didn't want to dig up the driveway again to install DC/solar wires. And yes, they are prone to oxidation so if anyone absolutely needs to use them, keep them indoors and...

Wife did not approve the budget for thermal cam :( But they were working fine ~2months ago before we moved. I even washed them so they're not dusty anymore :D

yes, my wife does the laundry so she makes sure :P

25c ish... but I would expect at least 80% efficiency for now, what I am seeing now i would expect in dec/jan...

Moved from 30 to 5 meters Orientation is 99% the same (might be a few degrees off, but not more than 5 and i think it's a steeper roof now Apart from solar panels, everything is tighten with specified torque. System is lift and shift, apart from new and shorter solar wires between panels and...

Victron Multi RS 48/6000 48v architecture East Europe No, 95% similar pitch ~20degree slope and south facing, no shading whatsoever Wires got shorter and better - the location i was previously using was not designed for PV so I only had 4mm2 solid wire and around 30m to inverter and using wago...

Hi guys! I just move some panels to a new location and when connecting them back to the inverter, I am not getting a much power as I used to. I have 7 canadian solar 375w which after (re)installation I can measure 240v (both with multimeter and inverter, which is a Victron) but I only get...

Hi guys! After having a similar need to recalibrate JKbms i ended up here :) You can somewhat trick the BMS without going trough a full cycle if you change the AH settings to a higher capacity (eg i changed mine from 230AH to 280 and it displayed 75-80% SOC). This will only work for top...

I might not be all 3.3v… just some (or rather another) weird accident. Ordered 2 more adapters that support both 3.3 and 5 to test out my theory. Those work on both 5v and 3.3v. The initial one (that worked) works on 3.3v. Weird stuff made in chaina and let’s leave it like that ? Below photos...

nope, that was one of the issues. same adapter started working after I switched to 3.3v

After MUCH hassle, i finally made it working ? It turned out to be a series of alignments in order to make it work on the JK BMS. First things first, many thanks @Louisvdw for all your effort. The code works perfectly! ? So, turns out the JK standard is a bit of strange one and it CAN be done...
