Direct answer: An off-grid pathway is organized around independent power continuity, load and battery behavior. A hybrid pathway also introduces grid-interactive operating expectations. The correct route depends on the project, not on a headline model label.
What separates the two routes?
| Review area | Off-grid path | Hybrid path |
|---|---|---|
| Operating context | Independent or weak-grid supply | Grid-interactive plus backup/self-consumption objectives |
| First inputs | Load, surge, autonomy, generation and battery | Grid rules, phase, load, export/backup objective and battery |
| Evidence focus | Load support, battery interface and operating range | Grid-side conditions, selected-market documents and battery compatibility |
Questions to send before an RFQ
- Destination country and site type
- AC phase, voltage and frequency
- Continuous and surge load profile
- PV input and battery architecture
- Monitoring, communication and installation needs
- Required certificates and document scope
What should remain unconfirmed?
A product-family fit does not prove that a selected inverter works with a selected battery. Exact pair, protocol, wiring, firmware and limitations require current supporting evidence.
Next step
Use this framework to prepare the requirement, then request current selected-model documents. Category-level guidance does not establish exact compatibility, certification, performance or commercial readiness.
