How it scores, by category
Market position
The data
Hybrid inverter
Manages PV, battery DC and household AC through the inverter platform.
- Product role
- The battery remains a separate product even when it belongs to the same branded platform.
- Published range
- 5–12 kW
- Phase
- Three phase
- Backup boundary
- Essential-load capability recorded
What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Warranty coverage: 10-year term
Coverage includes
Parts & labour · term longer than 24 of 93 scored inverters
No inverter in the fleet publishes a year-by-year performance or output guarantee the way panels and batteries do - this shows the covered term against the market-typical term and where every scored inverter’s term lands (grey dots, sized by model count), plus what the warranty actually includes.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. No succession from HYD 6000-ES is asserted. ESI S1 remains a separate single-phase family. Scored model: ESI-12K-T1 · checked 2026-08-07. Evidence.

Strong evidence coverage
25 of 25 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.
Record revision. ESI-5-12K-T1 datasheet V2.1.0, Australian warranty Version 2.4, current Australian catalogue and CER export retrieved 10 August 2026. First-market US and DE overlay review 2026-08-30: official regional catalogues recorded; Australian overlays and scores unchanged.

US Support Note
- Before
- Not previously recorded
- After
- SOFARSOLAR's contact region list names Germany/Austria/Switzerland, Australia, the UK and other territories. It does not name the United States. No official US host lists ESI-5-12K-T1. us.sofarsolar.com does not resolve. HYD 5-20KTL-3PH is not this PowerAll identity.
DE Warranty scope
- Before
- Not previously recorded
- After
- Germany; no German inverter warranty naming ESI-12K-T1 was attached, so six-field terms are not transferred from the Australian Version 2.4 factory warranty.
DE Grid and installation context
- Before
- Not previously recorded
- After
- Three-phase PowerAll inverter family named on the German product page. The manual documents VDE-AR-N 4105. DNSP and site settings remain installation-specific. ESI 3-6K-S1 and HYD 5-20KTL-3PH are different identities.
DE Certifications
- Before
- Not previously recorded
- After
- The German ESI-5-12K-T1 product page names 5 through 12 kW, including ESI-12K-T1. The manufacturer manual documents VDE-AR-N 4105 logic-interface and NA-protection functions for this family.
