The Solarman loggers were manufactured by the company Solarman and white-labeled by Ginlong. The Solis loggers are manufactured directly by Ginlong. I have summarized the key points below for clarification.
Every Solis logger works with every inverter, with one exception. The new S6 hybrid inverter has a USB port at the bottom instead of a 4-pin plug. Because of this, the S6 hybrid can only support USB loggers. Conversely, the USB loggers will not work with any other Solis inverter besides the S6 hybrid. This is, of course, until all Solis inverters have USB ports instead of 4-pin plugs.
How do you know if a Solis inverter has a USB port or 4-pin plug? Simple.. any model number with “S6” in it has a USB port and any model number with “5G”, “S5”, or “4G” has a 4-pin plug and no USB port. We do make a 4-pin connector to USB adapter, so technically with the adapter a USB logger could be installed on an inverter that has a 4-pin plug. I am requesting HQ make an inverse adapter, USB to 4-pin connector, so that 4-pin loggers can be installed on inverters with a USB port. However, that is several months out still.
