SolaX M3-40 three phase CT energy meter

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.

FAQ

SolaX SOLAX-M3-40 buying questions

You pay the ex-VAT trade price displayed on this page, with VAT added at 20% on the invoice. Quantity makes no difference to the rate: a single meter and a fleet order are priced the same per unit, and there are no minimums or spend thresholds to qualify.
As an accessory it goes out by parcel courier rather than on a pallet. Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment. If your order also includes inverters or batteries, those may ship as separate consignments, but the meter itself needs no one on site to receive freight.
8 in stock at the last catalogue update, and the count on this page comes from the live stock feed rather than a manual list. In stock means in stock; if the number reads zero, the trade desk can tell you the restock position for this part number.
