PVbutler provides basic info on how the solar system is working. Measurements such as solar production, battery charging and discharging and load consumption have been working fine, and can be exported to excel for analysis. But PVbutler has lots of bugs that need to be ironed out, such as in the “generation overview”, where it is not very detailed as to what some of the numbers mean or how are they calculated. I would also point out that on the “pv charge and discharge diagram”, it would be appreciated if the numbers were bigger. Also, installation could be made easier and with less bugs since it took about 3 or 4 attempts to get it working correctly. Lastly, I would like to see a graph of battery voltage, not just SOC %. Overall, it has been working fine, but these bug fixes would make life much easier for users and installers to use PVbutler .
