Sunsynk SDM120CT-M single-phase energy meter

The SDM120CT-M is Sunsynk's single-phase digital meter for storage systems, the part that lets the inverter see what the property is importing and exporting. It is a van-stock staple for installers fitting Sunsynk single-phase hybrids, and an easy save when a commissioning visit stalls on metering.

Description

A hybrid installation lives or dies on accurate grid metering, and this is the meter Sunsynk supplies for its single-phase storage systems. Keeping a couple on the shelf means a failed or missing meter never holds up a commissioning visit, because the part cost is small against the labour of a return trip. Ordering here is straightforward trade supply: the ex-VAT price on the page is the price on the invoice, held at any quantity, from UK stock.

What it pairs with

Fit it alongside Sunsynk's single-phase hybrids: the 3.6kW ECCO, the Sun 5K ECCO and the Acure 5.0kW all sit in the same catalogue, and the meter is the grid-sensing piece of that package. Meter requirements can vary by inverter model and firmware revision, so check the current Sunsynk pairing list before you standardise it across a fleet.

Single-phase only. Three-phase supplies need the Eastron three-phase meter listed alongside instead. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.

FAQ

Sunsynk SUN-METER-E-1P buying questions

The ex-VAT trade price is shown on this page, and VAT at 20% is added on the invoice. The price is the same whether you buy one meter or a boxful for the van, because there are no minimum order quantities and no spend tiers on a trade account.
It is a small, non-hazardous item, so it ships by parcel courier rather than pallet freight. Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment. It rides along with inverters or accessories on the same order, so most buyers add it to a larger basket.
3 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.
