    MPP Solar LV5048 Bonding & Grounding question.

    Sorry i havent been on in awhile, but i ended up ditching the bonding across the neutrals and run it as advised in the manual. Havent had issues with either but i don't like the idea of current going through the neutral into the output side.

    Texas/Southern 2021 Winter Power Outage MEGA-THREAD - Experiences & System tweaks welcome.

    So my experience was in the southern US. My setup is in my signature and hasn't changed much since the build. However, it definitely will be beefed up after this winter blast. I had no power for 36ish hours and rolling blackouts for the remaining 3 days. We ran generator power at night and...

    Texas/Southern 2021 Winter Power Outage MEGA-THREAD - Experiences & System tweaks welcome.

    After the Texas state wide power outages, I figured a mega-thread discussing how well our PV systems and backup battery banks fared. Pictures, experiences and knowledge learned would be of great help to the forum as well as the holes found in our systems. Which i did find quite a few holes in...

    MPP Solar LV5048 Bonding & Grounding question.

    Lv5048 does not have ground fault protection on its solar inputs. Youll need a GFDI breaker for the DC solar inputs. Its also not bonded. As a work around i bonded the neutrals on the output and input using a jumper to fix this issue.

    2 VDC Breakers are tripping! LV5048

    Sounds like too many amps through the breaker.

    MPP Solar LV5048 Bonding & Grounding question.

    Here is something i just considered. Are you running any loads directly from the gen? (As in plugged into it) Or is this gen only being used to feed the lv5048? Because a simplier solution would be to unbond the generator, only bond the AC output panel and carry the neutral jumper internally in...

    MPP Solar LV5048 Bonding & Grounding question.

    If your generator is bonded, the AC input panel should NOT be bonded. Make sure you still run the 4 wires from the gen to your input panel though. Generator should be bonded, lv5048 Neutrals connected internally, and the output panel of the lv5048 should be bonded. This way if the lv5048...

    MPP Solar LV5048 Bonding & Grounding question.

    It was discussed here. https://diysolarforum.com/threads/mpp-solar-lv5048-bonding-grounding-question.8955/#post-110961 Turns out a good solution for bonding.

    MPP Solar LV5048 Bonding & Grounding question.

    I would make sure your generator is bonded internally and then do this neutral jumper in the lv5048 continue its bonding down the line.

    MPP Solar LV5048 Bonding & Grounding question.

    Im not an electrician, but i can only tell you how it was setup for me. The principle is that current always wants to return to the source it comes from. It can take multiple parallel paths to do so. You bond the neutral and ground on the output side so that if there is a ground fault in any...

    New NEC code makes it impossible for DIY systems to be compliant

    Well Im using mpp units, so im not totally code accurate anyway. There is buildings with 80s AL wiring still operating just fine. Staying safe is relative.

    MPP-SOLAR LV6548

    UGH so frustrated. WHY MPP solar, You No tell me sooner! Looks like the 5048 might get cheaper though and Id get a 3rd one cheap to finish out my rig. However this 6548 or the growatt 12k off grid inverter are about the same price range... The MPP has a superior CC with higher voltage and the...

    Fire estinguisher for lithium

    I have a few Halon 1211 units also. I just use halotron1 because its what I could find and fill locally. What exactly in short is LC50? I thought Halotron1 was pretty good over my halon 1211 units.

    Nissan battery as additional storage

    What you should do is put all those cells into parrallel with each other and let them all balance. Once they are all the same voltage, then wire in series and use a BMS or active balancers to keep the cells within .1 volts of each other.

    Tell me about SolArk.

    The way i understood it is that rapid shutdown has nothing to do with the actual DC circuits going to the home, it is just a clause that requires rapid shutdown. Rapid shutdown involves lowering the voltage in the array to below 48v within 30s of time. So if you put a DC disconnect from the...

    MPP Solar LV5048 Inverter

    1. Looking at a 50 amp RV, 50x110v=5500W estimated max load. So you need a inverter than can in put out 5KW at 110v. The LV5048 is not the inverter you seeking as its split phase. Instead look at This inverter and running two of them together for 6000W in 110V. 2. If you ran two MPP units...

    Off-Grid Sol-Ark vs Victron questions

    The Sol-Ark is a string inverter, and I think optimizers are proprietary to SolarEdge stuff. I don't know if sol-arks work with optimizers.

    Has anyone bought from MPP Solar Taiwan seller on ebay?

    Yes, I bought 1 of my units direct from taiwan from MPP solar on ebay. However i would rather pay the extra 50$ for the other MPP Solar USA seller instead, they have better service.

    Wow this is pretty smart. No need to choose one or the other. FLAs are still cheap and have a small LFP pack to keep them nice and topped off.

    Voltage drop

    It sounds like you have voltage sag. Its common on SLAs and FLAs. Also you might have one weak cell pulling down the others.

    10-KW* DIY Install - MPP Solar LV5048 - 2x Tesla Modules

    Unistrut did save me alot of money. Id rather buy more batterys or panels than have to spend the extra on racking. Id eventually like to add 12 more panels, i got them for 60$ each used for 300 watts. I don't think i can find a better deal than used commercial poly panels. 5 years from now...

    10-KW* DIY Install - MPP Solar LV5048 - 2x Tesla Modules

    I like unistrut but it does have corrosion issues and its not the simpliest to bond panels together. I had to go to old school and run a 6 awg ground wire to every panel to bond things together. With iron ridge, i'd just have to bond the rails and not every panel. My panels are 72 cell so I...
