Solar panels are CURRENT SOURCES and NOT Voltage Sources like a battery. You can short any panel out for a day, week, month, or year with no problems. In fact that is how you test a solar panel. As CURRENT SOURCE current is limited and in a solar panel is Isc. A shorted panel cannot even heat up its own wires.

Max short circuit current 17.2A/17.2A" Voc: 40.8V "23 x Trina Vertex S390W panels in two strings" Assuming 11 & 12 panels in the strings, 12 x 40.8V = 489.6Voc for longer string. "Max input voltage 600v" 600V/489.6V = 1.22, which is plenty to avoid over-voltage in cold weather. Can you confirm how many panels per string?
Note: If your solar panel controller also has a regulated Voltage output (Voltage is never more than 12-13V DC) then the current supplied to the battery may depend on the voltage that the battery has.e.g if the solar output is 12.3V and the battery is 12V then the battery is only being charged by 0.3V and the charging current will be small.
The NS6326B has excellent constant voltage/constant current (CC/CV) characteristics. It uses a current mode loop control principle to achieve a fast dynamic response.

Be sure your solar panel is able to do that with the available lighting conditions. A switching regulator solution (such as is presented in another answer) can produce more output current than input current, but still must obey conservation of energy (power out < power in).

Open circuit voltage (V OC) is the most widely used voltage for solar cells specifies the maximum solar cell output voltage in an open circuit; that means that there is no current (0 amps).We can calculate this voltage by using the open circuit voltage formula for solar cells. We are going to look at this equation.

The Wattage rating of a solar panel is the most fundamental rating, representing the maximum power output of the solar panel under ideal conditions. You''ll often see it referred to as “Rated Power”, “Maximum Power”, or “Pmax”, and it''s measured in watts or kilowatts peak (kWp). On the other hand, the Short Circuit Current
A short circuit happens when an excessive current runs through an unintended path – you overload the system. Yes, you can short a solar panel, but you likely won''t cause damage to the panel in this way. A solar panel is

Thanks for all the help, guys! I followed the testing procedures as laid out by BB, JTDiesel, and Mike_S, and discovered that the solar output current didn''t change whether there was a single panel connected or all four connected to the solar controller (about 3A, with all panels and controller output averaging about 22V open circuit). This led
When you connect both ends of your panel and create a short circuit connection what ends up happening is the voltage across your solar cells become zero. Short circuit current is actually the largest amount of current that can be drawn out of your panel. So it's quite important to measure it for safety purposes.
Safety gloves and glasses to protect against electric shock. Follow these steps to accurately measure the short-circuit current of a solar panel: Select a Sunny Day: Ensure you are measuring Isc on a bright, sunny day to get the most accurate reading. Set Up the Multimeter: Turn on the multimeter and set it to measure current (Amps).
If you connect both ends of your solar panel you will get a short circuit connection. Now put your solar panel under light and take a clamp-on meter. Set it to DC amps and use it on the wire you just connected. And soon you will have a reading and that exactly is the short circuit current of your panel.
The short-circuit current (Isc) is a key parameter that represents the maximum current a solar panel can produce when the output terminals are shorted. Isc is critical for: Assessing Panel Health: Regularly measuring Isc helps in monitoring the performance and condition of solar panels.
Semiconductors are affected by temperature. And in high temperatures, the current carrying capacity of the module goes down and problems may occur. 59 Degrees to 95 Degree is a good range for Solar Panel. Why should you measure Solar Panel Short Circuit Current?
The answer is no, shorting connection won't harm your panel since your panel will most likely be able to handle it if it was made by a good manufacturer. Commercial solar cells have 28 mA/sq.cm to 32mA/sq.cm short circuit current. But here are a couple of things you have to know about for added safety
