Thanks for your response. Is the self consumption calculation as simple as if 800kWh were generated and 1000kWh consumed in 1h, then self-consumption is 100%? If yes, then this will always overestimate self-consumption, as generation & site demand are not usually fixed at a given power for 1h. Within that hour there are likely to be periods when generation exceeds demand, and self-consumption will be less than 100%. If I select 1-minute simulation, but I have only input half-hourly data, will PVSol synthesise minutely consumption data? Thanks, Haydn

Hello, If I import HH data into PVSol, does it use this when calculating self-consumption with an hourly simulation, or does it add the 2 HHs together and use hourly data? Further to the above, is the formula used to calculate self-consumption % simply 'if consumption is greater than PV output then 100%, if not then = consumption/pv output'? This would essentially assume that PV output and site demand is completely flat for each simulation period. Thanks, Haydn

Hi hotline_oh, I'm not exactly sure how, but it is definitely possible to accidentally remove modules from their inverters. This was not done in the inverter configuration window, but while changing the string layout. i.e. I was assigning different modules to the already configured strings to move them around the roof & give a nicer layout. I am now left with an inverter configuration that has a number of strings listed as "String 2 (0 Modules)". On 1 inverter there are 4 MPPTs with 0 modules assigned. It is really quite frustrating that I will have to go through the process of manually assigning the strings again.

Hello, I was editing the 'module allocations' (string layouts) of a few inverters & managed to accidentally remove some modules from their inverters. I think I clicked 'manual selection' which somehow unassigned them from their inverters. I have tried to find a way to reassign them to their inverters without deleting the entire string layout, as it has taken a long time to get this far. Could you please advise how I can reassign them? If I click configure I can only manage to assign them to a new inverter. Thanks, Haydn
