Thanks everyone for the information, appreciated. I have succeeded in getting the program link working using the USB RJ45 Extender ,cost me $32 and Cat5e cable.

Thanks lbenson

Thanks everyone much appreciated. Hippy I did the cable test and the "Break" does not come through. Another Question?, Using the old Picaxe serial cable 9-way ,connected to the AXE401 shield board, I connected the scope to pin 3 on the "9-way" and found it out puts -6v +6v. I'm worried this is...

Hi all I could do with some advise on if it is possible to program a Picaxe 28X2 via this device . -Link to Unit - I have data coming from the Chip to the 'Serial Terminal' on the PC one great step for me. If I can get the link to program as well would be fabiolus, I can't get it to work. Any...

Hi, I did it all, design, manufacture of the frame and also the electronics for the mppt and have just got one tower tracking as well, one tower to go.

Hi I have been ably to get to picaxe to communicate with the Pi, the driver listed worked for me. I had to follow the extra instructions when installing the driver, but it worked. I don't program the picaxe with the Pi I use it to get serial data to a data base.

Hi lbenson I've tryed to make the pole mounts good enough for 150kmh winds with panels parked horizontal. The system will be exposed to tropical cyclones so fingers crossed I did a good job.

Managed to tick off another todo box today The Raspberry Pi4 is now uploading data to PVoutput.com (DKB Hot water ) I am using Node-red to do the heavy lifting Next job is to build the auto tracking system (I move the system manually right now

Hi ferando Thanks for that info. I have been using a manual input to adjust the pwm, record the highest and then let it run and compare. I've been very happy with the results. PWM@100khz and voltage/amps sampling at 20 Hz the response is nice and quick under 1 second.

Hi JG Right now I ues my Pc. I'm trying to get my Raspberry Pi4 to handle the job. The Pi4 is uploading my data from the grid tie system. At the moment the Pi is very new to me so a big learning curve for me. My systems on PVoutput.org are : DKB Hot water & DKB PV4. 4

I just realized I have posted the wrong Software .The posted software is part of the system but not the MPPT controller. I'll attach it here

Hi premelec I already have a grid connect system and if I alter it in any way I will loose the feed back tariff of .44c/kw that I get now and go back to 6c/kw so no grid connect for this system. Hope to one day soon development this 2.1kw system to run my pool pump (700w) as well. The...

Hi lbenson thanks for that. First time that I've designed the PCB and put a system together, This is version 2. I have used the AXE201 28x2 Module The 96v is 2 panels in series and 3 lots of 2 connected in parallel to get the amps. I originally had the hot water element connected direct to the...

Hi, I have got my MPPT Unit up and running (2 months now). So I thought i would share any and all my info, to any one that it may be of interest to. The idea was to run my hot water system from solar . I was given 6 panels 360watt JA Solar (chinese brand) so I mounted them on 2 frames that i...

Hi All, I have just built a MPPT for my 2.1Kw solar array. I use the system to power my HotWater. The Picaxe 28x2 does the job very well, returns 95% to 85% efficency, very pleasing result, as this was my first design project. To answer the question can a Picaxe chip run an MPPT for me it is YES.
