  1. Mecer 5kVa settings and monitoring

    The batteries are 4 x Narada 12NDT200. The HA02 is wired each output to one battery, red to positive, black to negative, in sequence. As mentioned in another post for Narada's I put bulk at 55.8 and float at 53.8.
  2. Mecer 5kVa settings and monitoring

    Chris, I have a HA02 installed. I measured the batteries. They measure 12.6 - 12.7 - 13.4 - 14.0. All I can do is lowering the float and bulk charging voltage. I lowered both to 52V . the deviation is now less than 1V.
  3. Mecer 5kVa settings and monitoring

    My installation has been made safe.Battery monitor is installed with midpoint monitoring. Now I need expert opinion on what has been recoeded. Mostly battery midpoint is at 0.22., but rises...
  4. Mecer 5kVa settings and monitoring

    Thanks Plonkster. The one recommendation I had was to buy a Victron invertor and sell the Mecer 2nd hand. Is there a market for that?. At the moment the installation is doing its job. i will use this setup till it gives the ghost and then i upgrade.
  5. Mecer 5kVa settings and monitoring

    Next week Monday the doctor coming to sort out my installation. I found a reliable installer in the Nelspruit . Fuses, dc breakers, even dc cables will be replaced, battery monitor (702 with temperature sensor, grounding . it will all be done. I already have the trial ICC program running on the raspberry pi. I just have a question.about the BMV 702. Do i connect the BMV to the raspberry and if so with what kind cable, or is this no need..
  6. Mecer 5kVa settings and monitoring

    My HA02 arrived and is installed. My raspberry pi has arrived. I stll need the monitor and the icc program. My question now is more about the installation itself. My batteries are directly connected to the invertor, no fuses, no isolator, The solar panels have an isolator and i have switch to switch the load to solar/off/utility.. That's all. How safe is my installation? Then I took my Ohm meter to check the grounding of the invertor. The invertor is not grounded. I opened the isolator switch, the ground wire from the invertor goes a a ground busbar . no other wire is connected to this bar. I have written an email to the company that did the installation , i expect no answer. .

    Which firmware should I install? And where can I get it?
  8. Mecer 5kVa settings and monitoring

    I am still looking for a reliable installer in the Nelspruit region. There is another house with solar panels in estate where I stay. I will visit him and find out who installed his setup.
  9. Mecer 5kVa settings and monitoring

    Chris, I see you scratched out the HA02 on your signature , is it a luxury and not required? Another issue i have is the temperature of the enclosure, in my garage, where the batteries are installed. Even now early morning my garage is already in excess of 28 degrees, later in the afternoon the temperature in my garage rises well above 30. I can install a fan, that doesn't really drop the temperature, i only circulate warm air.. Is there a setting on the invertor i should be aware off? I did set 27 (Float) to 53.4 and 26 (Bulk charge) to 55.8.
  10. Mecer 5kVa settings and monitoring

    I see there is also HA-02. What's the difference between HA01 and HA02. Which one is recommended?
  11. Mecer 5kVa settings and monitoring

    I hate Windows, that's the only reason to go Raspberry. I run Ubuntu on my laptop. I am not a fundy on Linux,, but i can give it a good try. Can someone recommend an installer , I am too old to go on the roof., in the Nelpsruit area?
  12. I My setup consists of the Mecer 5kVa , 6 x 265 Watt Canadian Solar Panels, and 4 x 12NDT200 Narada batteries. I read nearly all the topics concerning the Axpert (Mecer) . I changed most of the setting accordingly. Thank to forum for the valuable information. The reason why i decided to buy solar was the first place to keep my fridge/freezer going during the very outages (in excess of 50 hours) we experienced here. The last outage, 3 weeks ago, 58 hours, my batteries went dead at 10.30 in the evening. But the next morning my fridge /freezer was already running at 6.30 in the morning. I know i didn't buy the best hardware but i have to do with what i have and make it work as optimal as possible. If i tell you the system was initially installed with 8 X Energiser deep cycle batteries. You probably know who installed it. They replaced these batteries as the system did not work. When they replaced these with narada batteries they changed setting 16 to Solar only...their comment was now it will work. After searching the forum i want to control the setup, possibly remotely, solar during the day , utility at night and when the load too high . What do I need? Monitoring software? BVM? I am getting a Raspberry Pi . Another question should upgrade the firmware on the Mecer.? Frans
