A dual MPPT design with 99% MPPT efficiency squeezes more out of your array, especially when panels face different directions. Hybrid charging pulls from solar and the grid together at up to 150A, and time-sharing scheduling lets you control exactly when the system charges and when it discharges. Stack up to 6 units in parallel for a combined 43.2kW. Renewable Outdoors is an authorized RUiXU dealer, and every SUNON7.2 is backed by RUiXU's 3-year limited warranty. 3-Year Warranty Lowest Price Guarantee Authorized RUiXU Dealer Free Shipping 0% APR Financing Expert Support: (303) 876-7654 Why the SUNON7.2 Stands Out 120V and 240V Output Runs standard 120V circuits and 240V appliances — a well pump, dryer, or mini-split — from a single inverter, no transformer needed. Dual MPPT at 99% Efficiency Two independent MPPT trackers let panel groups on different roof faces or tilts perform to their own maximum instead of dragging each other down. 150A Hybrid Charging Charges at up to 150A and can draw from solar and the grid simultaneously, so a large battery bank refills quickly. Stack to 43.2kW Up to 6 SUNON7.2 units run in parallel for a combined 43.2kW — enough for a large home or a light commercial site. Time-Sharing Scheduling Decide when the system charges and when it discharges, so you can shift usage off peak utility hours and keep more of your own solar. Rapid Shutdown & WiFi Includes rapid shutdown to de-energize the PV array for first responders, plus a WiFi dongle for app-based monitoring.

The surge rating, battery voltage range, dimensions, weight, and warranty length come from Renewable Outdoors' own product listing, since those figures live inside RUiXU's downloadable spec sheet rather than in text on their web page. We weren't able to link that spec sheet directly here — RUiXU's site serves it through a script-based download button rather than a plain URL — so we've left the Documentation section off rather than link a reseller's mirrored copy. 3-Year Warranty Every SUNON7.2 we sell is backed by RUiXU's 3-year limited manufacturer warranty.

The SUNON7.2 outputs both 120V and 240V, so it can run standard household circuits and 240V loads like a well pump, electric dryer, or mini-split from the same unit without a separate transformer. How is this different from the SUNON3.6? The SUNON7.2 doubles the continuous output to 7,200W, adds 240V split-phase capability and a second MPPT tracker, and nearly doubles the solar charge current to 150A. The SUNON3.6 is a 120V-only, single-MPPT, 80A unit — a better fit for smaller off-grid loads. Is the SUNON7.2 a grid-tie inverter or off-grid? It's an off-grid inverter. It can charge from the grid alongside solar in hybrid mode, but it isn't designed to export or sell power back to the utility — if you need grid export, look at the RUiXU RX-12K hybrid inverter instead. Why does dual MPPT matter? Two independent MPPT trackers let two separate panel groups operate at their own optimal voltage. If your array is split across roof faces with different orientations or tilts, dual MPPT keeps one group's shading or lower output from dragging down the other. What batteries can I use with it? The SUNON7.2 works with lithium-ion, lead-acid, or user-defined battery profiles on a 48V nominal bank, with a usable voltage range of 40–60Vdc. Can I add more inverters later? Yes. Up to 6 SUNON7.2 units can be stacked in parallel for a combined 43.2kW of output, so the system can grow with your loads. Does it support rapid shutdown? Yes. The SUNON7.2 includes a rapid shutdown function that quickly de-energizes the solar PV system to protect first responders, which is a code requirement in most modern residential installations. Can I monitor it from my phone? Yes. A WiFi dongle is included in the box, which connects the inverter to RUiXU's mobile app for monitoring production, battery state, and system status remotely. Do I need an electrician to install it? We recommend having any battery-based inverter installed by a licensed electrician familiar with your local code. Off-grid inverter installations involve high-current DC wiring, grounding, and rapid shutdown provisions that need to be done correctly and inspected. What's covered under the warranty, and do you offer financing? RUiXU backs the SUNON7.2 with a 3-year limited warranty, and we can help you navigate a claim as your retailer. We also offer 0% APR financing through Affirm at checkout and back every purchase with our Lowest Price Guarantee — call us at (303) 876-7654. { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ {"@type": "Question","name": "Can it run 240V appliances?","acceptedAnswer": {"@type": "Answer","text": "Yes.
