How far can you push a charge controller?

I'm looking at the EP Tracer BN 30 amp model because it physically fits into a build I'm working on. I really want to use 4 100 watt Rich Solar mono panels because they fit onto a cab rack on my Tacoma. The specs of the charger unit says max 390 Watt at 12 volt for PV input ..... do you think I can squeeze out that last 10 watts over spec for the PV input? The battery charger side will only deliver 360 watts (30 amps) to the 12 volt battery so I really wanted to get the most out of the system with 4 100watt panels, especially since they will be mounted flat and not ever be pointing optimally toward the sun. Opinions? ........

if your panels max voltage does not exceed the SCC max input voltage you should be ok.

I'm getting ready to do the same with my Epever 2206anLI. Max 12 volt panel is 260 watts on my controller. Ordering another rich panel to make it 300 watt. I never had a problem with my pwm controllers. We shall see!

I have always understood that you CANNOT exceed the voltage rating of a SCC but they are more forgiving if you push up against the current rating.

Thanks all, I'm going for it.

I would just check to make sure it isn't getting too hot. but like you said the chances of getting full output are slim most times.

CAN I USE A EPEVER 40A CHARGE CONTROLLER WITH A 3000 INVERTER, AND 2 BATTLE BORN 12V 100Ah BATTERIES? 2X200 s/p

yes you can but realize if your system is 24V you will make 960 Watts per hour max from SCC and 480 Watts/hour if its a 12V system. The BB batteries will only power Inverter at max poweer for about 30 Seconds though before the BMS shuts them down. They will do 2400 watts continuously
