Kevin Lourens Posted June 6, 2023 Share Posted June 6, 2023 Hi all, My sister was sold a Deye 5kw inverter and 8 X Canadian solar panels. Reading about amps of panels I am worried that it could magic smoke something. Nominal maximum power - (Pmax) 545W Optimum operating voltage - (Vmp) - 41.5V Optimum operating current - (lmp) 13.14A Open current voltage - (Voc) 49.4V Short circuit current - (lsc) 13.96A Maximum system voltage - 1500V Maximum series fuse rating - 25A Thanks, Kevin Quote Link to comment Share on other sites More sharing options...
Kalahari Cruiser Posted June 6, 2023 Share Posted June 6, 2023 (edited) Read my post to a similar question you posed yesterday In your scenario, those 8 panels seem like the perfect pairing, assuming they’ll be connected in one string in series, facing one direction. Again, just divide the inverter’s max volt input by the panel’s VoC spec (or multiply your 8 strings by the VoC of a panel), and you have what seems like a great pairing well within the inverter’s spec. Regarding the amps, should you go slightly over (per spec), then the inverter clips the current. I don’t think the panel spec poses any issue for your inverter but perhaps others can confirm.

Kevin Lourens Posted June 6, 2023 Author Share Posted June 6, 2023 Thank you very much for the advice, it's super hard to understand as some suppliers say out right you will blow the inverter. I will relay the information, need to research installers in CT, Jacobs bay area for installation around August. Quote Link to comment Share on other sites More sharing options...
