Hello calling all the solar experts!
We have a Victron 75/15, what is the maximum watt panel we can have?

Theoretically around 200w, but you could over panel a little, with the assumption one rarely encounters optimal conditions…

Approximately 15 amps x 12 volts = 180 watts (actually a bit higher than that because batteries can charge at 14v).

If you put a larger panel on, it'll produce as much power as it can. Which just means on clear days in the summer, it'll produce the same output as a larger controller until the middle of the day, when it'll top out at ~180 watts. But throughout most of the year, you won't hit the limit.

Useful to remember in many MH situations.....

Watts / Voltage = Amps

Eg.

120W / 12V = 10 Amps

Your solar panel will also have a sticker stating the potential maximum output to guide you.

Yes the 75/15 is rated to 220 watts.
I have a 75/15 running 2 x 115 watt panels so 230 watts.
The most wattage I've ever seen, in the UK, from my 230 watts is 204 watts.
