  1. Yeah. I use VNC viewer via VNC cloud to remotely manage the PI to access the ICC software. Additionally I use Dataplicity to access the web page remotely. It creates a wormhole which can be switched on/off.
  2. Yeah. I have 4 x 200ah Gel batteries.
  3. Setting 1 on the Axpert inverters. Solar first: Solar energy provides power to the loads as first priority. If solar energy is not sufficient to power all connected loads, battery energy will supply power the loads at the same time. Utility provides power to the loads only when any one condition happens: - Solar energy is not available - Battery voltage drops to either low-level warning voltage or the setting point in program 12.
  4. All good thanks, likewise. Thanks for the feedback. So my system was installed in Jan/Feb. My four panels are 1480w combined. I think the one day I got 1476w. Which is damn close to max! But that was in the summer months. Then I would get PV energy from 7am until 4pm. Unless it was a very cloudy day. I typically only load my system between 500w to 1000w. (Fridges, Computers, TV's, Lights) Now that it is cooler and very cloudy I am not getting much PV energy. I assume it is because we are moving into Winter that is causing this, and not that I had to change my inverter(due to issues with the 3k (24v) inverter). I now have a 4k (48v) inverter. So I am hoping that the lower PV energy is not the new inverter operating differently. However, just after the new inverter was installed at the end of March, there were a couple of days where a lot of PV energy was generated. With the 3k inverter I was at max panels, however with the 4k inverter, I can add another 5, which I will do soon. I do monitor my installation using the ICC software running on a Raspberry Pi. Just a note, I use SOL and not SBU mode. Cheers,
  5. A quick question re the settings available in the ICC Software. Specifically info on the 'Change Inverter Mode' button. It offers three choices: Utility, SUB and SBU. What is SUB, is that the same as 'Solar' in 'Output source priority' on the inverter? There are three choices on the inverter: Utility, Solar and SBU. If I change the mode, under what conditions will the inverter change back?

  6. Hi, A quick question re the settings available on the Axpert inverter. Specifically setting 31. Solar power balance: "When enabled, solar input power will be automatically adjusted according to connected load power." In layman terms what will the pro's / con's be of enabling it or disabling it? In my case I want to use my batteries at little as possible. (Setting 12 - Setting voltage point back to utility source - I have selected the highest voltage) I want them fully charged for loadshedding / power outages. I want my batteries to charge as fast as possible. (Setting 16 - Charger source priority - I have selected Solar and Utility) Inverter Info: Axpert Mks 4K 48VDC Inverter. 4 x 370W PV Panels 4 x 12V 200Ah Deltec (Valve Regulated Lead Acid (VRLA) Gel batteries Axpert MKS-MKS-1-5KVA manual-compressed.pdf
  7. Thanks a lot. I had figured thru other discussions that I need the RJ45 - RS232 cable (which I have) and then a Serial to USB converter (which I need to get). Thanks for the validation. The inverter is new, at lease new from the supplier.
  8. I will be replacing my Axpert 3K inverter with the Axpert 4K inverter. My question I am seeking an answer is this: Currently I connect my Raspberry Pi via the USB port on the Pi, to the USB port on the Axpert 3K inverter. How do I connect my Raspberry Pi to the Axpert 4K inverter as it only has an ethernet port? Do I connect the inverter and pi using an ethernet cable? If so a straight cable or cross over?

  9. Thanks Coulomb, Appreciate your assistance as always. Any idea where I can obtain the firmware and tool for the Axpert Mks-3K-24 Plus model? Regards, Tim
  10. Hi, I am trying to figure out what cable is required and what the process is to upgrade the firmware on my inverter. I only have the USB printer type port on my inverter. (see image below) I currently use this port for monitoring using an USB AB cable. I have read thru some forums and determined that the requirement is a rj45 to serial converter. (It was stated that one can not use the computers usb port to upgrade the firmware. Must be the rj45 port) But how do I then convert from rj45 to serial to usb AB?

  11. Hi, I am looking for advice on the values I should specify within the Inverter Control Center software on the Inverter MQTT settings tab. (ICC Software version 2.996 running on Raspberry Pi 3 Model B.) I have attached my current settings: ICC_Settings.jpg My assumptions: 1. PV Size must be set to 4 x 370 = 1480 2. Inverter system total watts = 3000 as per the attachment Axpert Mks 3K 24V.jpeg. I am not sure what Export Max should be. 3. Battery volts Normal: Must this be my 100% charged voltage? i.e. 27.6 4. What should the Battery volt Min and Max setting be? 5. What should the Battery volts Medium and Low values be?

  12. Correct latest manual that I could find Axpert-3KP-5KP-24V_manual_compressed.pdf
  13. I uploaded my comprehensive settings. Solar Inverter Settings All Models.xlsx
  14. Hi, I have just had my first inverter/solar solution installed. Axpert Mks 3K 24V Plus Inverter (Manual and Specs Uploaded) 4 x 370W PV Panels 2 x 12V 260Ah Deep Cycle Battery (Valve Regulated Lead Acid (VRLA) AGM batteries) My question is how do I configure the output source priority to get the most efficiency out of 1st PV, then 2nd Utility and then last the batteries? I want to ensure I have my batteries fully charged for loadshedding and want to minimize charging cycles and use of batteries. My assumption is that I should set: 01 - SOL And then set: 12 - Which option do I select to ensure I use the least amount of battery before switching back to Utility? 23.5V? And set: 16 to SNU to ensure it charges as fast as possible ready for loadshedding. Both PV and Mains will then charge the batteries. I am more concerned about having fully charged batteries than the cost of using Eskom supplied electricity to charge. Much appreciated for any assistance as I learn on this new journey.
