Summary

Big charger and switch, short Warranty

What it is: a 12 V inverter charger with a transfer switch and shore or generator charging for RVs, boats and backup
The trade-off: a compact all-in-one with fast switchover and a tough case, but few extras and a short prorated warranty
Not checked: the no-load draw and what the BMS port does; Rich Solar's manual could not be read
Look elsewhere for: built-in solar charging, app monitoring or stacked units

Strengths

Invertercharger and transfer switch in one box
Fast switchover between shore and battery
Strong shore chargeradjustable down

Description

The Rich Solar NOVA SUPERCHARGER 3K (model RS-V3P12C) is a 12 V pure sine wave inverter charger with a built-in transfer switch. It is rated 3,000 W continuous and 6,000 W for 5 seconds at 120, 110 or 108 V AC, 50 or 60 Hz, under 5 percent THD, with a 91 percent peak efficiency and above 85 percent at full load.

The DC side runs from the low-battery cut-off (set from 10.5 to 12.8 V) to 18.0 V and draws 288 A at full load.

Its three-stage charger is set from 5 to 150 A for LiFePO4 (with a BMS), AGM, gel and flooded batteries, charges a battery from 0 V, and is power-factor corrected above 0.98; Power Share lowers the charge current to protect a small generator or shore supply.

AC input runs 100 to 130 V, the transfer switch is rated 50 A and switches in under 20 ms, and a load search mode wakes the inverter only for loads above 25 W.

It has a GFCI, a 20 A supplementary protector, a multi-function LCD with status LEDs and four buttons, a BMS port, an ACC ignition input and a remote port for an optional remote panel.

The fan-cooled, marine-grade case is described as corrosion-resistant, vibration-tested and ABYC compliant, takes an optional drip shield, runs from -40 to 160 °F (derated above 122 °F), measures 15.4 x 12.0 x 4.8 in and weighs 18.5 lb.

Rich Solar also sells the NOVA SUPERCHARGER 2K (RS-V2P12C, 2,000 W, 80 A charger) at $649.99.
