Hi all,
I recently installed solar at home. I selected the Fronius Primo GEN24 5kw Plus inverter for future compatibility: it's hybrid (so I can add batteries) and it has two MPPTs (to add more panels). The current setup is a single string on MPPT1 (8 x 590W). I didn't add any more due to the cap on government subsidies (max 5kw in panels). I can reapply to the same grant next year as long as I install another 1kw of panels. The idea is to add another string on MPPT2.
And here is where I'm hitting a wall. The manual states that the max input current to MPPT2 is 12.0 A. For reference MPPT1 is 22.0 A.
But somehow there don't seem to be practically any panels that fulfil this spec? I've read through dozens of specification sheets for AIKO, JASolar, Canadian Solar, Longi, Jinko, and practically all of them (about 95%) have a listed Maximum Power Current - IMPP (A) above 12 A.
Is there something that I'm missing? Am I looking at the wrong number? Is it possible that Fronius has such little compatibility?
I would rather not install panels that are going to constantly clip.
Thanks!
