Hey everyone! I'm new to solar setups and I need some advice. Right now, I've got a Kings folding solar panel connected to a King's 20amp MPPT, which is charging two Kings 175Ah batteries and powering a 3000W inverter. Recently, I received four additional solar panels—three rated at 250W each and one at 300W. I want to connect these roof panels on my RV to a Victron Smart Solar MPPT 150/85 and use them to charge the same batteries as the Kings setup. I measured each panel with a multimeter and they output around 35V. Is that too high for a 12V system, or is that what the controller is designed for? Also, will this setup work as intended? On top of that, I have a Victron Energy DC/DC Charger that runs from the RV motor. Appreciate any help!

No worries! An MPPT controller is designed to handle that. It will take the higher voltage from your solar panels and convert it to the proper voltage for your battery system. The Victron MPPT can handle up to 150V, so your 35V from each panel shouldn't be a problem at all. Just make sure the current ratings of the panels (Imp) are similar so you can connect them in series if needed. That way, you'll get the best performance out of your setup!
Yep, that’s the way to go! Just ensure they're all compatible for best results.
Got it! So, would you recommend connecting them in series since the Imp values are similar?
