primitive yet efficient, cheap no-name brand pc fans have been running continuously for 13+ months sucking air on both sides of the inverter and dropping average temp by 10 degrees C ... KISS 🤩

Please Note: As of 2018-07-10 Development and support of this product has ceased. The code below and and comments remain, but only for review and implementation into your own projects. This code is completely free of any license or restriction of any kind (other that the KLEVA name and Logos which are under copyright and Trademark laws)
 
Description:
KLEVA Solar Monitor is NOT a replacement for the other perfectly usable products out there for your home use. KLEVA Solar Monitor was born out of a need to log data to an internal SQL server, and to automate a scheduling system that could remain running with custom commands. You are expected to have at least basic database configuration knowledge to be able to use this product. Basically, KLEVA Solar Monitor should actually be one of your last resorts in getting data from your system.
I wanted something that could be run independantly for multiple devices and still use the same database. I wanted something that could run on practically any MS Windows version released in the last 15 years and I also wanted something that was flexible to be able to be added onto using a base framework, and to be able to give other developers a tool to communicate with their devices, without having to master all the communication protocols, etc (as I had to), just by including this open source Core file. (All source is available on request, and will be posted somewhere for future generations )
KLEVASolarMonitor will remain open/free, but support at a later stage (should this suddenly by magic become a hugely successful product), may need to be charged for by my current employers if it occupies my working/business hours.
Installation:
1. Extract the contents of the zip file to any directory on your hard drive
2. Read the currently slightly disorganised KLEVASolarMonitor.pdf file in the Docs folder for details
3. Contact me below regarding queries/support/issues or via the email address in that file
Other:
Also attached, but not really part of the KLEVA Solar Monitor per-se, is a sample of how I  occassionaly read the data into some nice little pretty graphs (courtesy of Google Graphs).

Alas, measuring "available" (as opposed to "presently used") PV current or power is a tricky business. I think I heard of a Pi or similar connected to a sensor that was like a small solar panel, that gauged the "strength of the sun", from which you could estimate the available PV power.

I assume you used apt-get to install it? If yes, then it should be as simple as removing the packages again: apt-get --purge remove mosquitto mosquitto-clients.
I'm not sure how Manie starts up the daemon. Back when I was still building a pi-based system (before I decided to stick that effort into Venus instead), I wrote down some instructions on compiling your own, which I had to do because the version that ships with Raspbian Jessie is old and somewhat buggy. Those instructions are here.
There is also a systemd configuration file to start it automatically, here.
Not saying you should do what I did, Manie will know best, but at least that's some instructions you can use if you wanted to do your own.

Thanks so much guys!
We are 2-3 weeks away from Launching the Powerforum Store!
Lots of meetings have been taking place - not too worry!
Its going to be good! Please note the current powerforum store is outdated. The new one with new products to come!
Logistics is 110% sorted at the best rates! You click, pay, items arrive at your door!
Something Exciting! We even have a Powerforum Installer Nation wide , if you so need!  The installer will also assist with CoC.
Also financing will be available!! Thus we will be able to handle everything for you from start to finish! We even have a Doctor of Engineering onboard! If that helps :> Awesome down to earth guy.
Do not worry about the small details now. Just know its going to be GREAT!!!!! We throwing our hearts at it 24/7 and working 24/7!
Sincerely
Jason

Is there a particular reason for having such a large pump? Is it running irrigation or something? It is more suitable for a solar system to have a smaller pump running for longer, than a large pump running for a short period of time. You will also use less power as a large pump creates a large cone of drawdown around the borehole because of the volume of water extracted. A smaller capacity pump doesn't pull the water table down so quickly so you will pump from a shallower depth.
