Summary

Long Solar strings, single phase per unit

What it is: a 48 V all-in-one off-grid inverter with 120 V output, two high-voltage MPPT inputs and a 120 A AC charger
The trade-off: high solar input and six-unit stacking, but 120 V only from one unit and a short prorated warranty
Not checked: Rich Solar publishes no no-load draw for this model, and its linked manual is for the earlier RS-6548S
Look elsewhere for: 240 V from a single unit or a longer unprorated warranty

Strengths

Strong solar input on long panel strings
Parallel stacking for larger systems
Fast transfer in UPS mode
Built-in Wi-Fi monitoring
Closed-loop battery communication

RedditBrand-level4 out of 10

Scope: few Reddit threads name Rich Solar, and those found are complaints
Battery: an r/SolarDIY owner's new ALPHA 5 read 6.7 V instead of 48 V, and Rich Solar's technician had not returned his call after two days (August 2023)
Order: an r/SolarDIY buyer waited from March for an out-of-stock ground mount, then was told its price had risen from $180 to $699 and cancelled; the refund took months (May 2025)

GoogleProduct-line6 out of 10

The Solar Lab: tested the NOVA 6500S, an earlier 6.5 kW model in this line now sold out, and measured 1.1 to 1.2 A at idle, about 60 W (October 2024)
Load: it delivered its 6,500 W rating and ran a roughly 7,300 W load
Verdict: a solid purchase for simple 120 V off-grid setups, held back by a clunky setup, a dated app and no 240 V from one unit
