RachelEnergy Posted April 18, 2023 Report Posted April 18, 2023 PV Sol has suggested I can input three strings into one tracker for a Solis inverter. However the manufacturer's design software only enables 2 strings. Why has PV Sol recommended an option that isn't possible? I've attached screenshots of both designs. I'm using Trina TSM-420DE09R.08 panels and the site is in Colchester, UK. Quote
developer_mh Posted April 21, 2023 Report Posted April 21, 2023 Hi RachelEnergy, recently, another user had the same issue: We made some minor changes to PV*SOL premium 2023 R4 in order to make it more obvious to the user that there are cable combiners necessary in some occasions. Kind regards, Martin Quote
RachelEnergy Posted April 25, 2023 Author Report Posted April 25, 2023 Thanks Martin, that would be a useful addition to advise cable combiners are needed if there's more than 2 strings per input. The manufacturer has since confirmed an issue with their software, it should allow 3 strings as it's within the voltage range but there was an glitch and it wasn't allowing it, but an older version was.

RachelEnergy Posted June 8, 2023 Author Report Posted June 8, 2023 Is there a way of telling the program not to suggest more then 2 strings per tracker? I've checked the settings but can't see the option for it. Quote
developer_mh Posted June 9, 2023 Report Posted June 9, 2023 Hi Rachel, no, there is no option for limiting the number of strings to a given maximum. But I will put it on our list. Thanks for the recommendation. Kinds regards, Martin 1 Quote
