Solis S1 Wi-Fi + 4G stick, 4-pin, with SIM
This version of the Solis S1 arrives with the SIM already supplied, alongside its Wi-Fi capability and 4-pin connection. It is the pick for installers who want the monitoring line item to be one order and one box, with nothing extra to source before commissioning.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Every separately sourced component is a chance for a job to stall, and SIM procurement is a classic example: the hardware arrives, the card does not, and commissioning waits. Taking the with-SIM S1 removes that step entirely. For smaller firms without a fleet airtime contract it is usually the quicker route to a monitored handover. Pricing follows the trade pattern on every page here: the ex-VAT figure shown, no volume conditions, and stock held in the UK so the stick travels with the inverter order.

What it pairs with
Fit it across the Solis single-phase families listed here, such as the S6 Mini and the S6 dual MPPT ranges, matching the 4-pin connection to the inverter's comms port. Pairing can vary with model generation and firmware, so run the combination past Solis's current compatibility list. The no-SIM 4-pin S1 is the sibling to choose when you supply your own card.
This is the 4-pin connection version; a USB-connection sibling is listed separately. Cellular operation depends on mobile coverage at the install address. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
