Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The score uses the exact SG150CX bin named on the V7 sheet linked from Sungrow India's SG150CX card. Scored model: SG150CX · checked 2026-09-03. 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.

Summary
- Before
- Not previously recorded
- After
- SG150CX has a published local Modbus register protocol. Direct RS485 access uses Modbus RTU; optional Ethernet Modbus TCP requires a supported WiNet-S, WiNet-S2 or Logger1000 path. The protocol excludes iHomeManager and other communication modules from that documented route. The exact inverter manual connects SG150CX to iSolarCloud, whose Developer Portal offers cloud monitoring APIs after developer and application approval, with plant authorization and package limits. Cloud access therefore depends on permissions, connectivity and the service; it is not a local REST API or SunSpec certification. The manual instructs users not to connect a third-party RS485 data logger at the same time as the communication module. A supported monitoring API does not establish a named live VPP or every cloud dispatch command for this model. Confirm the supplied module, firmware and permitted connection arrangement before integrating another controller.
