RUiXU RX-12K Split-Phase Hybrid Inverter

The RUiXU RX-12K is an all-in-one hybrid inverter built to run entirely off-grid, assist the grid, or sell power back to it. With up to 11.4kW of continuous split-phase output and an integrated 200A transfer relay, it's sized for whole-home backup — not just a handful of critical circuits.

Four independent MPPT channels take in up to 17.1kW of solar, and the RX-12K works with either lithium (LiFePO4) or lead-acid battery banks on a flexible 48V configuration. Renewable Outdoors is an authorized RUiXU dealer, and every RX-12K we sell is backed by RUiXU's 10-year limited warranty.

Why the RX-12K Stands Out

Whole-Home Backup

An integrated 200A transfer relay delivers up to 11.4kW continuous — enough to back up an entire home, not just a few critical circuits.

All-in-One Hybrid

Runs fully off-grid, assists the grid, or sells power back to it — with AC coupling to retrofit an existing solar array.

17.1kW of Solar Input

Four independent MPPT channels take in up to 17.1kW of PV — enough headroom to grow your array over time.

Lithium or Lead-Acid Ready

Flexible 48V battery configuration works with either LiFePO4 lithium or traditional lead-acid battery banks.

IP65 Indoor or Outdoor

An IP65/NEMA 4X-rated enclosure means it can be installed indoors or outdoors without an extra weatherproof cabinet.

Generator-Compatible UPS

Separately connects to a grid or diesel generator input, with UPS-style switching in 20 milliseconds or less to protect sensitive loads.

This spec sheet also covers RUiXU's RX-5K, RX-7.6K, and RX9.6K models in the same series — the RX-12K's figures are the ones referenced in the table above. We couldn't locate a manufacturer-hosted (or Shopify-hosted) copy of the RX-12K operation manual specifically — only reseller-hosted copies — so it isn't linked here per our manufacturer-only sourcing policy.

10-Year Warranty

Every RX-12K we sell is backed by RUiXU's full 10-year limited manufacturer warranty.

RUiXU RX-12K: Frequently Asked Questions

Can the RX-12K back up my whole house?
Yes. Its integrated 200A transfer relay and up to 11.4kW of continuous output are sized for whole-home backup, not just a handful of critical circuits — final sizing still depends on your home's total load.
What batteries can I use with it?
The RX-12K works with either lithium (LiFePO4) or lead-acid battery banks on a flexible 48V configuration, with a battery voltage range of 40–60V and up to 240A of charge/discharge current.
Can I retrofit my existing solar system with this?
Yes. The RX-12K supports AC coupling, which lets it integrate with an existing grid-tied or off-grid solar system without replacing your current solar inverter.
Does it work with a generator?
Yes. The grid and a diesel generator connect separately, and the inverter can store energy from the generator — useful for extending backup runtime during longer outages.
Can it be installed outdoors?
Yes. The RX-12K carries an IP65/NEMA 4X-rated enclosure, so it's built for both indoor and outdoor installation without an additional weatherproof cabinet.
How much solar can I connect?
The RX-12K has 4 independent MPPT channels supporting up to 17.1kW of total PV array power, with an MPPT voltage range of 90–550V.
What's the difference between the 120/240V and 120/208V modes?
The RX-12K supports both a standard 120/240V single-unit split-phase configuration and a 120/208V service configuration, so it can be matched to your home's or facility's electrical service type.
What certifications does it carry?
The RX-12K is UL1741 CRD certified, IEEE 1547 compliant, and also carries UL1699B and UL1998 certification with UL9540 listing.
What's covered under the warranty?
RUiXU backs the RX-12K with a 10-year limited warranty. As your retailer, Renewable Outdoors can also help you navigate a warranty claim — call us at (303) 876-7654.
Does Renewable Outdoors offer financing or price matching?
Yes. We offer 0% APR financing options through Affirm at checkout, and every RX-12K purchase is backed by our Lowest Price Guarantee — if you find a better price elsewhere, call us at (303) 876-7654 before you order.
