ACOPOWERAll Black 100 Watt 100W Mono Solar Panel with MC4 Connectors for 12V Battery Charging

Is there anything else I need to hook this up to the battery in my travel travel to keep it charged?

what voltage and amperage are you getting direct mid-day sun?

It appears the 20 a pwm controller is a positive ground, rv is a negative. is that ok if connected direct to battery?

What are the specs on the diode in each junction box?
