48V Hybrid Inverter · 6,500W · High-Voltage PV Input
The NOVA 6K pairs a high-voltage 120A MPPT solar charger with 6,500W of pure sine wave output and a 13,000W surge rating — built for longer PV strings and simplified system design, for homes, RVs, cabins, tiny homes, ADUs, and off-grid systems.
PV Input
| Max. PV input power | 8,000W (4,000W × 2) |
| Solar charger type | MPPT (dual) |
| Max. PV open circuit voltage | Up to 550 Vdc* |
| MPPT operating voltage range | 90–230 Vdc |
| Max. PV input current | 18A × 2 |
*Rich Solar's own product listing for this model states "550V PV Input" in its title and features as this model's key differentiator, while a separate specifications table on the same page lists 250V — a figure that matches other 6500-series siblings and appears to be reused rather than specific to this SKU. Confirm the exact maximum PV voltage against the official RS-H6548V5 specification PDF before designing panel strings around this figure.

It's positioned as a high-voltage PV input variant, aimed at systems that benefit from longer panel strings and simplified wiring compared to Rich Solar's standard 6,500W hybrid inverters.
Rich Solar's own listing states up to 550V as this model's headline spec, though a separate spec table on the same page shows 250V — check the official specification PDF or contact Rich Solar directly to confirm before designing your panel string around this figure.
Yes — it switches in as fast as 10ms in UPS mode (20ms for general appliances), fast enough to keep sensitive electronics running through a power interruption.
Yes — a cold start function allows it to power up and operate even when there's no utility power present.
Yes — up to 6 units can be paralleled for expanded capacity.
