Check the VOC rating of your panels
Max VOC of 30 so does not work with Renogy Shadowflux 120W panels (33.7 volts VOC) but I like those panels. This probably should only be used with panels that are 25 or less VOC. The DC to DC function may be worth keeping at the sale price but some of the reviews say it doesn't start charging until your battery is below 12.6 volts. If that is true, that would be a deal breaker. I'm looking at a Victron 100/30. I may keep this for the dc to dc charging function or just get something else for the DC DC charging. I like Renogy stuff and have it in my other camp setup, but do your research, everything must be compatible.
