I currently am using a MPPT 150/35 driven by 3x150Wp of Solar in parallel on my sailing yacht. This is well within the specs of the 150/35, which says 500W max. Usually I see around 350 up to 400W maximum at around 24-25A due to partial shading, which can't be avoided in a sailing environment.
Now I'm thinking of adding another 150Wp for a max. of 600Wp. That will give me hopefully another 6A to load my 12V house bank, but still below the limit of 35A. The manual says max. 500Wp but will limit outgoing current if oversized. But it does not say anything about the limit.
Is the limit the max charge current of 35A?
Does it do any harm to the 150/35 if I put 600Wp to it but still below the max. charging current?
Thanks in advance
