How to get started with a setup that already has produced a lot of Wh?

API
#1

I’m migrating from Sonnenertrag and hence my setup has already produced quite some Wh. I want to change my automatic pushing to push to the API of pvoutput, but when trying to do this (to the https://pvoutput.org/service/r2/addstatus.jsp API) I get:

Bad request 400: Energy value [64958719] too high for system size [4100]

And since I’m not allowed to post data more than a couple of weeks in the past, I can also not push the historical production and hence can never counter this jump from “no data” to the actual energy value my system in the meanwhile has produced.

So, my question is: how do I get this thing started. I don’t want to subtract the already produced value as that seems somewhat ridiculous. I have (up to the minute) historical info of my production, but if I cannot upload that history it also doesn’t help me …

Thanks in advance …

Hi @misterke,

I think that the error message that you are getting relates to the energy / power value(s) that you are pushing in comparison to the size of your system that you have set up. If the inverter settings in PVO are for a 5000W inverter but the power / energy push is from a 10kW installation that would indicate a problem to PVO. [ Sanity checking of input data ]

Is your new inverter’s output capable of exceeding the original inverter? Did you alter the 'SYSTEM" settings in PVO to match that of your new installation?

Are you pushing LIFETIME or DAILY energy values? Are you using the c1 flag in your push string?

Just a few thoughts.

Hi @grannos , thanks for the reply. I indeed had missed the need for having a c1=1 parameter.

Hi @misterke - I’m glad that my thoughts weren’t too wide of the mark :smile:

Welcome to PVO.
