What can you tell me about my converter/charger?

If you have not already purchased your battery consider a Trojan SCS Gr 31. That series batteries are heavier, better quality and have more capacity compared to generic 12V deep cycles. We do fine with a single SCS 200 Gr 27 and run our vent fan all night when dry camping. Do daily morning charges and monitor voltage and charge current. Been doing this for years.
