Solis inverters use RS485 modbus to communicate information. Please use the modbus map attached to this article to poll data from the inverter. This map works for every series of Solis inverters sold in the US except for one. The only inverter series to use a different map is the RHI-1P(5-10)K-HVES-5G-US series. Please click here for that modbus map.
An NDA must be executed before the modbus map can be shared.
