Rich Solar NOVA SUPERCHARGER 3K | 3000W 12V Pure Sine Wave Inverter Charger | UL 458 Certified

Overview

A 12V inverter charger that gives 3,000W of pure sine wave power with 6,000W surge and switches between shore power, generator and battery. Its charger is adjustable from 5A to 150A, and Power Share lowers charging current when AC loads need it. The marine-grade housing is corrosion resistant, vibration tested and ABYC compliant.

Who it's for

RVs, boats and cabins on a 12V battery bank that plug into shore power or run a generator some of the time.

Common questions

Will it charge lithium batteries?
Yes, LiFePO4 batteries with a BMS, along with 12V deep-cycle and AGM.

Can it recover a very flat battery?
Rich Solar lists fast charging and recovery even from over-discharged states.

Is it made for boats?
It has a marine-grade, ABYC compliant housing and an optional drip shield.

What's the difference from the SUPERCHARGER 2K?
3,000W instead of 2,000W, and up to 150A of charging instead of 80A.
