I’m a solar newbie so thanks for your patience with these questions. I have a new trailer with 440w of roof solar and an Epever (sp?) MPPT. I want to add a portable solar pan thinking 200w. 1) I want to add a 2nd MPPT is the Victron smartsolar 100w/20a large enough? 2) If I switch out the factory MPPT for the Victron 100w/30a large enough? 3) Any advice appreciated on which portable 200w panel. Would like something on the lighter side. 4) I also want to add a solar disconnect switch for the 440w panels. Looking again for product advice. I don’t have a lot of space in the trailer.
