  1. Hi, I hope that some one can assist. We are installing a second inverter at a customer that already had a Growatt inverter installed. so making this a 10 kw system. The customer's inverter is a Growatt SPF 5000TL HVM. And my inverter is a Growatt SPF 5000TL HVM-P. The customers inverter did not have a Parallel card installed and which mine one do have one installed by the factory. So I purchased a card but when it arrived, I only notice after that I have installed the card, the pins on the connector are different than the inverter I supplied. Mine has 15 pins and the card I purchased and installed has 9 pins? Now I am sitting with two inverters that cannot communicate? Is there any way around this? I do have 4 new parallel cards for the Apxert Machines. These pins on the connector are identical but will they work in the Growatt? I did try to look at the card already installed in my Growatt and the two does look exactly the same. Pins and all. Except for the CN3 and CN2 on the two cards are switched around??? Will this work?? Also I have the latest fw for the inverter to update but did not get this far yet. Any help will be appreciated.
  2. Hey All, Does these settings include the SPF5000ES version?
  3. Hi Coulomb, excuse the late reply. thank you for clearing this up for me. regarding the pv production, I did notice that the production is never stable when there is load. I am just concern about the state of charging when it is on float. I also notice that the when it is on float the one inverter show 53.8v and other 54v? the inverter with the lower voltage is the one flashing constantly and very fast. this happens on the one inverter and then on the other, so never on the same inverter. at first I thought it was the battery connection but I did redo all cables and still the same. could this be a fw bug that is causing this or internal components? it did the same with the original fw and the new fw recently uploaded.
  4. Hi All, I am a bit confused in setting up my two Axpert MKS 5kva/5kw Inverters (SOL-I-AX-5P). (Both running FW dsp_LC1_74.40e pf1) I have successfully connected the two in parallel and want to change settings on it. I used watchpower to configure the inverters, and how I understand it, I only need to change settings on the master inverter (MS/HS) and it will change the slave inverters with the same setup??????? So when I confirm on watchpower that all settings passed through on both inverters I see that all has updated accordingly. (Both is showing the same settings) But when I check on each individual inverter physically on the screen, only the "Setting 11 - Utility charging" stayed the same on the Slave inverter? (Master = 10Amp (My settings) and Slave =30A (Default Setting)) Seems that all setting changed except for this function and only show different on the screen of the inverter. Do I need change it manually or leave it as is and it will continue charging on both inverter at 10A? Also I get another weird light flashing on the charge light when It is fully charged and in a floating state. This light flashes constantly and very fast (Not the normal charge or in use flashing), also you can see the battery icon dropping bars on the one inverter and then on the other. Any reason for this should I be concerned? Thank you
