    Off-grid Solar / Battery monitoring and control freeware

    Hallo can anyone explain how to getMPPSolar.sh I installed mpp solar python with: What output / settings I have too use to get it working with node_exporter.

    MPP Solar - utility charge only when inverter off?

    Well, if you set Set Step 16 to OSO is only should charge from solar. I do have a 5048 MGX, if I switch the device of, it's charging only with solar.

    MPP Solar, stop from utility charging?

    Ok, well still learning to unterstand the PIP but my understandig so far is: 1. If I select SBU - it will use solar / battery fist. If the requested power is not sufficiant it will switch to utility (Bypass). But not charging the battery using utiltiy. But if you request e.g. 1000W and solar is...

    MPP Solar, stop from utility charging?

    Well, I have a 5048 MGX and so far I seems ok for me. No utilty charing, if not neccessary... But it's still not under full load... Check this out: https://www.mobile-solarpower.com/all-in-one-122448v-packages.html

    MPP Solar, stop from utility charging?

    Well check wiki: https://diysolarforum.com/ewr-carta/diy-lifepo4-charge-profile-parameters/ 12V LiFePO4 Battery w/ BMS: Absorption: 14.5V Float: 13.6V Inverter Cut-off: 10.7V-12V (depending on size of load and voltage drop etc) Nominal voltage is 3.2*4 = 12,8V Sure if you like not to stress...

    MPP Solar, stop from utility charging?

    Your "problem" is Setting 12 - Voltage 12V This is the nominal voltage for the battery. It have to be lower eg. 10.5V then It will charge with untiltiy until you hit the voltage of step 13 This is my understanding of this settings.

    MPPSolar Transfer time for Bypass to long

    Sure, if I wait for Low Battery Cut Off, it may act different. But if the BMS cut off earlyer I will have a longer transfere time. Well the capacitors will loose voltage instandly, after droping under a sertain threshold the inverter can switch powersource.

    MPPSolar Transfer time for Bypass to long

    Well, I'm not sure what's right. It's not realy stated from which power soure the transfere time to another. In fact Unitlity / Grid is the lowerst priority. Just backup if solar and battery are not sufficiant... How does the "famous" PIPs like 2024MS behave? And discharging the capacitors...

    Chargery BMS, DCC (Solid State Contactor) thread.

    I know the video / tutorial. Just like to know if I connect my DCC to negative. How I can precharge... this could be a solution...

    Chargery BMS, DCC (Solid State Contactor) thread.

    ok this is intressting. In the manual 1.0 the negativ installation for common port is shown: In Version 1.1 it's on the positve side using he ISO-Board Would it be possible to have precharge using the delay board ? So if you connect to negative side, just use the delay board + additional...

    Chargery BMS, DCC (Solid State Contactor) thread.

    Just another question to the DCC experts, maybe I missed it, but the thread is quite long now - When the DCC is shut-off, you should be able to measure 7,5kOhms? - It always provide a voltage! => This will cause the inverter so see always "see" the battery. But if power is requested it will...

    MPPSolar Transfer time for Bypass to long

    Hello, I may have a problem with my MPPSolar 5084MGX inverter: My transfer Time is way to long! Is there any setting beside Step 03 - AC input voltage range ? According to the manual it should by: Transfer Time: 10ms typical (UPS) 20ms typical (Appliances) If I simulate a load with 1kW...

    MPP Solar + BMS communication/control

    ok, well just to make this clear. I did't found any informations about the lib protocol so far... This would be the key to do some conversation. In fact I got this from MPPSolar for asking for lib protocol: https://diysolarforum.com/resources/mppsolar-bms-communication-protocol.206/ Are there...

    MPP Solar + BMS communication/control

    As I posted just a few postings earlier. 5048MGX does have lib protokol. I checked mppsolar webseite, and the newer models like MGX oder MAX do have extended BMS support. You have to check STEP 5 in LCD Menu: - AGM - User-Defined - Pylontech battery - WECO battery - Soltaro battery - BAK...
