MC4 branch connectors rated 30 amps

Follow up on this thread. I'm impressed after switching from the ground mount solar array and parallel 4 to 1 MC4 branch connectors to series setup at my off grid cabin in far West Texas. Adjusted the solar array to 35 degrees facing south/south west for December/January. Also changed to series setup on the 4-195 watt panels on roof of the cabin that has a very slight slope to the east. Seeing a lot more solar watts producing over a 1000 watts at 1:30 pm with the dual Rover charge controllers. Thinking about adding a fifth matching 200 watt panel to the ground mounted frame where I previously had a small 150 watt suit case solar kit. Following the calculation and example posted by Crowz, I should be OK not to fry the Rover. Currently have 50 amp circuit breakers between the panels and controllers but think the in coming amps will begin to trip the 50 amp breaker with five 200 watt panels. Saw 725 watts on the Rover screen with the 800 watt solar array. How to safely protect the Rover from too much amperage?
