Technical FAQs 4

What is the difference between an inverter and an EPM?

The inverter is responsible for the DC to AC mains step-up required to use the energy generated by the photovoltaic (PV) cells for grid-connected appliances in the house, and for backfeeding into the grid when there is an excess of generated power. The EPM is simply measuring the power flowing in/out of the house.

Which Power Manager is suitable for all solar PV Grid tie inverters?

The export power manager is suitable for use with all solar PV grid tie inverters. Model: Solis-EPM1-5G(for single phase system) Solis-EPM3-5G( for three phase system) Solis-EPM3-5G-PRO(for three phase system).

How do I access my Solis inverter and EPM data?

After flashing the ESPHome config and plugging in the node, you should be able to access your Solis inverter and EPM data from Home Assistant. Do note that since you will not be able to use the original Solis Wi-Fi stick concurrently with ESPHome, your solar production and consumption data will not be getting sent to Solis.

How many inverters can EPM control?

EPM can control max 60 inve rters (Different models are allowed). The system can ONLY has one grid connection point. Inverters that connected to EPM can be monitored by Ginlong Monitoring device. (WiFi/Cellular/LAN stick) NOTE: When inverter connected to EPM, no other monitoring device is allowed to be connected to the inverter. 1.
