  • Post in thread: Deye 6k PV solar panels options

    Thanks mate! So should i hook MPPT1-8panels, MPPT2-8panels = 16 panels total? this way i will be getting constant 7800 or so in cloudy days, if the sun shines bright and i exceed 7600W of the inverter would not be able just to grab right? Can you check on my panels, are they cool choice for me...
  • Post in thread: JK PB2A16S-20P No Communication

    JK BMS as i know doesnt have RS232, or not just implemented yet. Its empty on that port. What i did is plugged in RS486 not to Master, and now i have devices 0-6 visible, but read only mode. (d@mn.) Why did they do that, have Parallel lighted up in right corner and other are greyed out.
  • Post in thread: Anybody tried new JK BMS with inverter communication support?

    As for PC communication software bug. 2.7.0 version: When connected to master RS485, see only master (read only mode) When connected to slave RS485, see all master+slave (read only mode) 2.1 OLD Version: Individually connect to device address grants access to BMS settings. So it is Software...

    I have two Deye 6K hooked to a large 24kWt powerbank on Li ion NMC on one Busbar One will be PV+batt second one feeds from batt only . Thats my goal So in discharge i will be having 2x6kwt maximum so it suits me Im worried about MPPT overvoltages and over amperage (inverter is 13A, solar panel...
  • Post in thread: Deye 6k PV solar panels options

    My chosen solar panel is Isc 12.97A and Imp is way higher 13.78 - Is there any worries about that, or i should only worry about Voc overvoltage configuring the strings ? I made a calculation in Sol-Ark calc and used their 5k Inverter they show it as 10400W mine is lower, but the main thing...
  • Post in thread: Anybody tried new JK BMS with inverter communication support?

    Hey all. I jumped in a new project. Took salvaged Tesla 3 battery pack (was mint, not a single dent) it had CATL factory 175A cells 106pcs. found 4 more and made 7x16S battery packs. 64Kwh stored. And i used PB2A boards from JK. So i have 1 MASTER (address 0) and 6 SLAVES 1-2-3-4-5-6 There are...
  • Post in thread: Solar Assistant graphs freeze up

    Have the exact same problem. Have meanwell din psu, tried 4.99V, 5.2V, 5.4V. Tried different RS USB converters. Tried different PSU Tried joining beta channel for any firmware change about this. when i was running 2 inverters all was fine, when i added 3rd inverter to SA. i get the data just...

    How do i clone an SD card not to loose the data? Can you share the process you make to do that? It is really the last thing i didn't try
  • Post in thread: JK PB2A16S-20P No Communication

    Im having similar problem with 1Master and 6 Slaves. All i can have is comm read only with MASTER with no option (it says parallel and all are greyed out) any Device 1 2 3 or else are shown as disconnected.
  • Post in thread: Solar Assistant graphs freeze up

    I have such freezes every day once or twice Data just stops. Power supply is not an issue. I have meanwell din rail power supply which i trued 4.95V 5.2V 5.6v, same on all voltages When i reboot SA, or disconnect connect by button rs-usb converters all goes fine
  • Post in thread: Deye 6k PV solar panels options

    Im not sure how i will do that, i first wanted to start and fill one inverter with PV (2 strings) and then fill the other one with 2 strings. But now im in concern of making my 2 inverters use a single string each, and then add the second string in future. this would be less heat production and...
  • Post in thread: Deye 6k PV solar panels options

    Im in a start of building a PV field with two Deye 6k Inverters and didnt brought anything, im in Europe Ukraine, sun is expected to shine 4-5 month on good basis, all other is very shady weather. We have only Risen and Longi solar panels on market Attached inverter specs-and solar panel specs)...
