Check

Know it fits.

A clear verdict for each inverter and battery pair, and where it comes from.

Open this compatibility page
Open this compatibility page. A compatibility verdict from Minute Solar: "Yes — compatible." Supports 1–3 battery modules. The provenance line reads that Minute Solar records the SolaX X1-Hybrid-5.0-G4 with the SolaX T-BAT H 5.8 V3 (T58) as compatible (A — Automatic), read from recorded specifications, and that no manufacturer approval is recorded. A Datasheet source tag sits beneath.
The public verdict for the SolaX X1-Hybrid-5.0-G4 with the T-BAT H 5.8 V3, with its condition and where it comes from.

Draw

Catch it on screen, not on site.

The schematic flags problems early, like a CT lead that won't reach the meter.

Open this schematic. The schematic builder's metering view for the same system. The edit panel shows a supplied CT lead length of 5 m (sample) and a warning card headed "Grid CT reach / sample check: CT lead is too short — 15 m route · 5 m supplied lead · 10 m short. Choose a supported meter arrangement or ask the manufacturer."
Example: a 15 m CT route against a 5 m sample lead. The 5 m is the builder's illustrative sample, not a manufacturer figure.
