Solis S6 Mini 1.5kW 1-MPPT inverter
A common service-van pick, the S6 Mini 1.5kW is the size that gets called on when an ageing inverter on a small legacy array gives out. Single phase, one MPPT and a DC isolator in the box make it a straightforward replacement proposal.
Description
Replacement work rewards inverters you can fit without drama. This one covers the small-system band that early domestic arrays commonly occupy, and because it is current Solis stock you are quoting a new unit, not hunting an obsolete model. The isolator arriving with it matters on a swap: fewer parts to source, less time on the wall. Keep one on the shelf and a dead small system stops being a two-visit job. For the array itself, check the string against the S6 documentation before you commit to reusing it as wired.

What it pairs with
If the old system had no monitoring, a swap is the moment to add it: Solis data logging sticks come in 4-pin and USB fittings (SOL-S2-WL-ST and SOL-S2-WL-ST-USB), matched to the inverter on Solis's pairing list. The 100A current transformer for the 4G, 5G and S6 range (SOL-CT-100A-10M) handles consumption and export sensing.
1.5 kW output on one MPPT; single-phase supplies only. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
