    Upgrade from MPP Solar LV6548 to new LV6548V, increase from 250v max voc to 390v

    Appears I got the answer first so I’ll share it here. Not mention, great deal on lv6548, $1,100: “ “

    Lv6548 fault F08 issue

    I encountered the same F08 fault error, downloaded and applied the MCU 112.19 firmware update and problem resolved. In the process I came across another firmware update, "LV6548 DSP." Curious what this is and if I should apply it as well. Searched around and can't find anything about it other...

    Upgrade from MPP Solar LV6548 to new LV6548V, increase from 250v max voc to 390v

    Been searching and can't find anything regarding the option to upgrade from LV6548 to LV6548V. I just emailed MPP Solar. Figured I'd ask you all also to see if you've heard anything.

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    The unicorn seems to be an outdoor. I’ve been searching/watching eBay, Craigslist, Offer Up, and Facebook marketplace, contacted every seller on Google... The only outdoor box with 40 spaces I found is a metered one (slap a meter socket cover over it) but the guy is profiteering wanting $600...

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    Thanks for the video. I like the custom interlock, i am definitely going to have a mechanical safety precaution for bypass, I might use that. I watched the whole video, actually a lot of similarities to what I have, some other stuff I learned from it. My biggest problem now is finding a...

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    Appreciate the feedback. Some good considerations. Would also free up a couple of spaces. If it came to selling and I wanted to keep the system I could also reverse the circuits from the sub panel and Route them back into the main panel. Lots of options.

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    Here's what I'm thinking for AC input from grid for 5 inverters. Feedback appreciated:

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    Yes on the 60a 2-pole 4 awg. Regarding inverter N-G bonds, they do, and have to be dealt with. From what I've read, all LV6548 internal N-G screws need to be removed except the one primary unit. The only N-G bonds should be in the lead inverter unit and the main panel. The sub panel will...

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    Hoping to resolve this with out learning the hard way. When I thought it would be a great idea to add grid power to the mix I didn't realize the complexity I was adding! o_O

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    The way I've been operating throughout my testing phase which is how a Will Prowse video and the MPP Solar manual suggest commissioning: 1) Turn on battery-to-inverter circuit breakers 2) Turn on batteries, allow to boot 3) Turn on inverters one at a time (if you wait too long between inverter...

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    Similar to you, mine is mainly an off grid system with no back feed to grid, but when I learned you can program the inverter to prioritize power using the internal ATS (1) solar; 2) batteries; 3) grid) I thought why not have grid setup as the third priority power source, just in case. Obviously...

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    Good point. How would I go about looking up the "right" way to wire this based on the NEC?

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    Wow! Very good point. If it allows bypass power from any power source that would not be good. Thanks for the heads up.

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    I was thinking both, this configuration on input and output side. It would eat up more spaces but I have the extra. I could also remove all the bars so each hot input/output is on an independent circuit. Just not sure if this is the "right" way to set them up.

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    It's really a great design. I figure also, let's say a few years down the road, one unit goes bad, I can just reprogram the remaining units to suit my needs.

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    @Samsonite801, please see link above from MPP Solar (https://www.mppsolar.com/v3/catalogs/supplement%20parallel%20diagram%20to%20SPLIT%20PHASE%20LV.pdf). So long as you have the communication connections configured correctly and as you note it programmed correctly in the software, they will run...

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    I have tested output voltage by shutting any number of units off so long as one unit is on from the 1st phase and one unit is on from the 2nd phase. Will continue to output 240v in split phase. My concern is that depending on how AC input/output is configured, would this impact operation on...

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    Hi, for the LV6548 it can be setup with anything from 2-8 units. Here's the split phase wiring diagram that MPP Solar shared with me: https://www.mppsolar.com/v3/catalogs/supplement%20parallel%20diagram%20to%20SPLIT%20PHASE%20LV.pdf

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    Thanks for the feedback. I'm probably missing something, but would 3 60a 2-pole circuit breakers on the main panel achieve this? Two of them would provide 4 hot leads to AC input on 4 inverters, the last one I would only use 1-pole of the 2-pole breaker to provide input to the 5th inverter...

    MPP Solar LV6548 AC Input and Output Main Panel and Sub Panel Wiring

    Hello all, I’m trying to understand the wiring diagram and circuit breaker requirements from the main breaker to 5 LV6548 inverters AC inputs, then the 5 inverters AC output to a sub panel? Inverters 1-3 are in 1st phase, inverters 4-5 are in 2nd phase. Plan is to program LV6548’s to provide...
