Summary

Split phase outdoors, No published surge

What it is: a 48 V split-phase hybrid inverter with 120/240 V output, grid export, two MPPT inputs and a 200 A charger
The trade-off: split phase, an IP65 case and grid-tie modes in one unit, but no published surge rating and a short prorated warranty
Not checked: Rich Solar publishes no surge rating or no-load draw for the NOVA 12K
Look elsewhere for: heavy motor start-up loads off-grid

Scope: few Reddit threads name Rich Solar, and those found are complaints

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)

Complaints

No surge headroom off-grid
Shut down under its rated load
Very quiet fault alarm

Read the full summary

The Solar Lab: tested it with Rich Solar server-rack batteries and measured nearly 150 W at idle (January 2025)
Load test: it ran at 9,000 W or less until the battery drained, alarmed at 9,500 W and shut down after about 90 seconds at 9,900 W
Surge: it could not start a large compressor alongside a 1,500 W load; Rich Solar told the reviewer the unit relies on the grid for surge
Verdict: workable for systems without large start-up loads, but hard to recommend at its price

Description

The Rich Solar NOVA 12K, model RS-H12K, is a 48 V split-phase hybrid inverter rated 10,000 W continuous at 120 V, 208 V or 240 V (41.7 A per phase), from battery or grid.

Its manual gives a 91 percent DC-to-AC efficiency and lists off-grid, grid-tie and grid-tie-with-backup modes, with an off-grid transfer of under or about 15 ms. Solar input is two MPPT trackers of 18 A each (30 A maximum), a 120 to 550 V MPPT range, 600 V maximum and 12,000 W of PV power.

AC input takes 85 to 140 V per phase at up to 60 A and 10,000 W, with a separate generator input. It charges and discharges a 48 V lead-acid or lithium battery at up to 200 A, with RS232, USB, BMS and Wi-Fi ports and the i.Solar app.

Built in are a 300 A DC breaker, a 60 A AC breaker, arc-fault detection, rapid shutdown, ground-fault and PV lightning protection. The case is IP65, rated from -13 to 140 °F with derating above 113 °F. Up to 6 units run in parallel for 60 kW.

The manual gives 215.5 x 515 x 715 mm and 51 kg (112.4 lb); the 2026 spec sheet gives 8.5 x 20.3 x 31.4 in and 108.0 lb. In the box, per the manual: the inverter, an RS-232 cable, a parallel cable, current-sharing wires, a CT, a manual and software CD, fixing screws, a Wi-Fi antenna and a wall-mount bracket.

Rich Solar also sells it in the NOVA 12K PV Hybrid Inverter Solar Kit (KIT-SR0002) with 61.44 kWh of ALPHA 5 PRO batteries at $25,999.99.
