Solis Export Power Manager EPM3 5G PRO Three-Phase
The Solis EPM3 5G PRO is a three-phase export power manager designed for smart energy management across residential and commercial PV systems. This unit provides active power limitation and intelligent control for up to 20 Solis inverters via RS485 wired communication, with support for both single-phase and three-phase Solis inverter products up to 480V. The EPM3 5G PRO enables installers to set precise export values that satisfy local grid regulatory requirements while maximising self-consumption of locally generated PV power. The UK version ships with an integrated Solis datalogger and energy meter in the box. Manufacturer part number: SOL-EPM3-5G-PRO (MPN: Solis-EPM3-5G-PRO). Available from DECO Group, a UK solar wholesaler supplying professional installers.

Common Questions
- How many inverters can the Solis EPM3 5G PRO control?
- The EPM3 5G PRO supports intelligent control and monitoring of up to 20 Solis inverters simultaneously via RS485 wired connection, including inverters of different power ratings.
- Is the Solis EPM3 5G PRO compatible with single-phase inverters?
- Yes. The EPM3 5G PRO is a three-phase unit but works with both Solis single-phase and three-phase inverter products up to 480V.
- Are CT clamps included with the Solis EPM3 5G PRO?
- No. CT clamps are not included and must be sourced separately. The UK version ships with a Solis datalogger and energy meter in the box.
- What is the difference between the Solis EPM1 5G and the EPM3 5G PRO?
- The EPM1 5G (SOL-EPM1-5G) is designed for single-phase systems only. The EPM3 5G PRO (SOL-EPM3-5G-PRO) is a three-phase unit that supports both single-phase and three-phase Solis inverters up to 480V, with a wider input voltage range and generator integration capability via the Eastron SDM630 V2 meter.
