Can’t help you. I only measure in freedom units.

Say we have the Multiplus creating our N/G bond and is feeding a main service panel from the AC out. Do all EGCs from equipment enclosures, solar panel frames, etc. run back to the Multiplus or can they be terminated in that service panels grounding busbar?

Why would the controller blow before the fuse if the fuse is before the controller?

Things happen. And when they do, I like my expensive equipment to have a chance at surviving.

I think I’d get SCC(s) that were appropriately sized for my specs. You can still over size your array for your needs without over paneling the SCC.

Ahh I see what youre asking now. The SCC will see a short circuit when the panels short circuit. So technically if there’s never a short circuit I would assume everything would work fine and just clip the excess power above 20A. If you’re worried about damage to the SCC just add a 20A fuse...

Max short circuit current for that 100/20 controller is 20A. I’d stay under that so you don’t risk damage to the controller.

Seems like the 24v and 48v tend to be more efficient

They do sell the a larger 3/8” version. But then all your lugs would need to be 3/8”. A couple companies make pure copper bar attachments to go from 5/16” to 3/8” https://shop.explorist.life/shop/all-products/victron-lynx-adapter/

I’ve had good luck using an impact crimper in a bench top vise grip instead of wailing on it with a sledge. More precise and controlled crimp. I always felt awkward trying to hold the wire in the lug in the tempo crimper, then swinging a 5lb sledge where my hand was. I’ve done up to 2ga in...

Any chance you have a screen shot of your VRM page showing that 90% efficiency at that load? I’m not always at 70%. I’m currently sitting at about 75% 1692-673 = 1019 769/1019 =75% efficiency * As you can see the DC power now shows a 187w draw but I only have my cerbo connected to DC at...

I do have DVCC set to max 150a charge but I thought that limited the charge controllers from producing more than 150a for some reason. I just messed around with it does seem I can allow more than 150a from charge controllers while still limiting the battery from charging above 150a.

I would think 200-500watts of dissipation would be fairly significant in heat inside the multiplus. I love my Blue gear and still think it’s superior to a lot of other brands but what a bummer seeing all that wasted power.

You obviously didn’t re read the post…the DC calculation on VRM is an estimate. It’s not accurate in my case. I literally only have the cerbo (3 watts) and a small DC light (5 watts) which isn’t even on. The DC draw I’m seeing on VRM jumps around wildly from 10w to 300w every couple seconds and...

I have 1920w (6 320w panels) array feeding a 150/100 mppt that maxes out at 1450w into the battery I also have a 500w (5 100w panels) array feeding a 150/45 mppt that could potentially max out at 630w into the battery but I’m only getting about 450w right now from the 500w of panels. I’m...
