MPPT 100/20 virtual load output max current

Hello!

How much current can the virtual load output (alternate TX function of the uart) provide. Will it be enough to drive an optocoupler?

Well, premium priced product without premium customer support... Never mind - I found out myself: a PC817 series optocoupler with a 2K input resistor works flawlessly from the virtual load output. Didn't try to determine the maximum current the TX-pin is capable of. But apparently the 2.5 mA are enough to drive the opto.
