Thanks Pete, each pair is in series(24v) for the polychrystaline pair the vmp is 17.3 per panel(voc 20.6v) x2. & the vmp on the mono pair is 18v per panel(voc 22.25). x2. Would an mppt controller just see the combined voltages from both sets of panels,ie (34.6 +36=70.6) as 1input , which it would be as its only being fed by 1pr of cables from the junction box ? I already have a 10A pwm controller,would i be better off just buying another pwm controller for the second solar bank,then connecting the feeds to the battery banks isolater switch? By the way this is a great forum,& non of the usual yanks spouting nonsense.

Hi, i have 2 banks of 24v batterys,(connected in parallel) to an isolation switch fed by 2 banks of solar panels. Solar panel bank 1, has 2 x 80w monocrystalline panels,approx 4.5A maxoutput. solar panel bank 2 has 2 x100w polycrystalline panels,approx 6A max output. ? if i connect both solar panel banks to a junction box, then run a feed from the junction box to a 20A mppt controller,will the mppt controller be sending approx 10.5A to the batteries via the isolation switch ?
