The solar card within the J35B-L / J35D will limit the maximum input to ensure your batteries do not become overcharged.
It is safe to have a solar system that can produce slightly more power than the maximum solar input on the J35B-L / J35D. If the watts are exceeded , it will shut the solar down for approximately 2 minutes. Then, turn it back on, once the wattage has dropped back under the input.
