NOVA PURE MAX 2K - 2000 Watt (2kW) 24 Volt Industrial Pure Sine Wave Inverter

This is the 24-volt version of Rich Solar's 2,000-watt pure sine wave inverter, and the voltage is the whole point. At 2,000W and the >88% efficiency Rich Solar publishes, a 24V bank supplies roughly 95 amps where a 12V bank would need about 190. That halves your cable size, your fuse rating and your voltage drop.

Why this inverter

• 2,000W continuous with a 4,000W surge, which covers the start-up spike of most single motors - a residential fridge, a small well pump, a compressor - though not two of them at once.
• True pure sine wave output, so induction motors, CPAP machines, microwaves and switch-mode power supplies run without the buzz and extra heat that modified-sine units cause.
• Three 120V AC sockets and a 5V/2.1A USB port on the unit itself, so small loads do not need a separate power strip.
• Certified to UL 458 and CSA C22.2 No. 107.1, the mobile-installation standards an RV or marine inspector will actually ask about.
• Protection is automatic across the five common failure modes: overload, low battery voltage, over-temperature, output short circuit, plus an internal DC backup fuse.

Wiring and installation

• Budget for roughly 95A of continuous DC draw at full output. Size your cable and DC fuse from that current figure, not from the wattage.
• Confirm your battery bank's BMS is rated for 95A continuous discharge. Most 24V lithium batteries are, but verify rather than assume.
• Published operating range is 14°F to 122°F. Below freezing this unit is outside its rated range, which matters for unheated bays and lockers.
• The chassis measures 16.1 x 9.6 x 4.0 inches and weighs 10.1 lb. It needs clear air at the fan end.
• This is an inverter only. There is no solar charge controller, no battery charger and no transfer switch in it. If you need the unit to also charge from shore power, look at the NOVA 2K12 or a hybrid inverter instead.

Warranty and marketing claims

• Covered by Rich Solar's standard limited warranty. Ask us to confirm the current term for this model before you order.
• Rich Solar markets this unit as the "#1 Ranked 24V Pure Sine Wave Inverter." No ranking body, publication or basis is named anywhere in their materials, so treat that line as advertising rather than an independent result.
