SolaX M3-40 three phase CT energy meter
Three-phase sites need three-phase metering, and the M3-40 is SolaX's CT energy meter for installers fitting X3 hybrid or retrofit inverters. It suits commercial units and larger homes running on a three-phase supply.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
The catch-out on three-phase jobs is arriving with single-phase parts, and the meter is the easiest item to miss on the order. Listing the M3-40 against every X3 inverter you quote keeps surveys honest and avoids a stalled commissioning visit while the right meter is couriered out. For firms running both single and three-phase work, holding this alongside the M1-40 covers both supply types with two part numbers. Trade terms apply as standard: the price on the page is the ex-VAT figure, whatever the quantity.

What it pairs with
Its natural partners are the three-phase SolaX units in this catalogue: the X3 G4 Hybrid Pro inverters at 10.0kW and 15.0kW for new hybrid systems, or the X3 G4 RetroFit 10kW AC coupled inverter for battery additions to existing PV. SolaX revises its inverters over time, so check the manufacturer's current pairing list for your exact model and firmware before locking the design.
This is the three-phase meter in the range. For single-phase installs use the M1-40 instead. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
