What happens if a 12V battery exceeds the input voltage?Let's say you have a 12V battery and it is at 13.6V. The 50A output would be reached at 680W input. If you were able to get 800W, the SCC would just "ignore" the extra power and you would just get the 50A output. No damage would be done. But as you've seen, exceeding the input voltage can be bad. Exceeding the output current is a non-issue.
How much current can a battery charger provide?Normally you would not expect more than 3A from such charger, however since there are large capacitors at the end of its internal circuit, charger is capable of providing higher inrush currents. To account for all this information I have set the current limit to 4.2A.
Is overpaneling a battery a problem?Exceeding the output current is a non-issue. Overpaneling is fine as long as it can't ever result in exceeding the input voltage. Assuming the 50A is the rated max output current to the battery then if there is enough wattage coming in that would exceed that output current then the output current is simply limited to the max, 50A in this case.
Can a 3A Charger power a current limiter?I have a 3A charger powering the current limiter. Normally you would not expect more than 3A from such charger, however since there are large capacitors at the end of its internal circuit, charger is capable of providing higher inrush currents.
What happens if you over voltage a CC?Over voltage can destroy a CCs electronics instantaneously. If you are lucky the components will cease to work until the the V drops back to a safer V. Over current may take a little longer depending on the amount.
How do I avoid destroying my SCC?What to watch out for not to destroy your SCC is the Voltage feeding the SCC PV input, you should also factor in about 15% more if you live in cold weather since the VOC of the panel will go up in cold weather. MPPT can/will control the current. Over voltage jumps over the component ratings and the magic smoke is releas
