Wiki about Eversolar perl logger
The software is mainly documented in the code, this wiki is more focused on how to set up the hardware, supported software and interesting facts for anyone wanting to build a cheap monitoring system
Current typical setup is a Raspberry Pi, one USB to RS485 port connected to one or two Eversolar inverters. There are people using ethernet to RS485 adapters, RS422 adapters and desktop pc's or NAS boxes. Anything goes, but remember to consider the power consumption, this solution is going to be working 24x7x365, so the power saved by using a light system may pay off within a year or two.

How to setup the system using a single file that contains a working operating system with all software installed. ONLY on Raspberry Pi model B and model 2. The old image does not support Home Assistant integration! Raspberry 3 and 4 require full install! The image is way too old for such new systems.
How to setup the software stack required from scratch, you're IT savvy, if this your path. The dockumentation is from old PRI 2 systems, newer OS will be a tad different
