Before this, never had need to install RSD with Sol-Ark but doing project now that does. SolArk manual very clear on the pins to use but the APSmart manual leaves some open questions.</div>

Question is: How many strings of PV Modules can I route through single coil?</div>

Here we have four strings of 9-modules so I'm well below max string length of 30. But the manual is silent on number of strings through a coil. There is max amperage rating thru the coil (which looks like CT) but is it just one string per coil? Hope not. Each
APSmart transmitter can handle two coils. Here is pic for reference from the SolArk manual.</div>
