I think the answer will be no but I need to ask. I have 2x Panasonic hit 330w panels each with a max voltage of 58 volts connected in series, these are connected to a victory 150 35 smart controller. I would like to add a third panel. This would knock ybe combined voltage over 150. Please advise
Hi ajf.
Panel Voc of 69.7 ? ftp://ftp.panasonic.com/solar/specsheet/n325330-spec-sheet.pdf
Depends on how cold it gets, maybe you shouldn't even have 2 in series.
Maybe 3 parallel would suit a 24v battery, though would need string fusing and cable upgrade.
System voltage 12v I assume and the answer is no indeed. Try the handy calculator on their website. If it was 24v you could get away with 3 in parallel. Also, you typically use VOC for rule-of-thumb calculations.

I forget to mention it is connected to a 48 volt battery bank
The voc voltage is 71 volts
