24V Off-Grid Hybrid Inverter · RS-H3024X
One box, three jobs. The NOVA MAX 3K combines a 3000W pure sine wave inverter, an 80A MPPT solar charge controller, and a multi-stage battery charger into a single compact unit — built for RVs, off-grid cabins, marine systems, and home solar setups that don't have room for a wall of separate components.
Supporting solar, utility, and generator input, the NOVA MAX 3K delivers stable off-grid energy in a space-saving footprint — no separate charge controller, no separate battery charger, just one inverter that handles the whole job. It's a straightforward way to add reliable, clean power to a rig, boat, or cabin without stacking multiple components in an already-tight electrical bay.
A 3000W pure sine wave inverter powers sensitive electronics and everyday loads alike, without the voltage spikes or waveform distortion that cheaper modified-sine inverters introduce. With 6000W of surge capacity for five seconds, the NOVA MAX 3K can ride out the startup draw of compressors, pumps, and motors that pull far more than their running wattage the instant they switch on — a common failure point for undersized inverters in RV and marine setups.
The built-in 80A MPPT solar charge controller accepts up to 3000W of PV input across a 90–230VDC range (250V max), squeezing more usable energy out of a solar array than a standard PWM controller would under the same conditions. For a 24V off-grid system, that's enough headroom to run a meaningful rooftop or ground-mount array without needing a separate charge controller taking up space and budget.
Overload, over-temperature, and short-circuit protection are built directly into the NOVA MAX 3K, and it's rated to keep working reliably from 14°F to 104°F — a range that covers most off-grid environments, from cold-weather cabins to hot summer RV trips. If utility power drops out and comes back, the unit restarts automatically, so there's no manual reset needed after a brief outage.

Yes. It has a built-in 80A MPPT solar charge controller that accepts up to 3000W of PV input (90–230VDC, 250V max), so no separate charge controller is needed.
Yes. Up to 9 units can be run in parallel for flexible system expansion as power needs grow.
The NOVA MAX 3K restarts automatically once AC power is restored — no manual reset is required.
Pure sine wave. That means clean, stable AC power suitable for sensitive electronics as well as everyday appliances.
