I've got five 100-watt Renogy solar panels on my RV that connect to a Zamp junction on the roof. Ideally, they should be providing decent power, but ever since I switched to an Epoch lithium battery and a Victron charge controller, I've noticed that even when it's sunny outside, the charge controller usually shows that I'm only pulling about 50 watts total. I've updated the settings for lithium batteries, but something seems off. Any ideas on what might be causing this low output?

First, check how the panels are wired up. If you have multiple panels, the way they’re connected could affect their output. If one panel is shaded or not functioning optimally, it can limit the performance of the others. Also, if you could share the specs of the panels, that might help identify the issue. Let’s see how they’re cabled!
Got it! The layout seems fine, with two on each side and one in the middle. That's a good setup to avoid shading issues since two panels in series could drag the performance down if one gets covered.
