What stands out
- A hybrid architecture combines PV conversion and supported battery conversion in a single wall-mounted inverter.

- Three or four MPPT channels allow designers to accommodate multiple roof orientations without module-level optimizers on every panel.
Match the inverter to the proposal, not just the logo
Ask the installer for the exact inverter model, AC rating, compatible panel range, expected clipping, rapid-shutdown architecture, monitoring hardware, battery compatibility and backup configuration. Those details can materially change the system even when two proposals use the same panel brand.
