The RUiXU SUNON3.6 is a compact off-grid inverter built around a 48V battery bank, delivering 3,600W of continuous 120Vac output with 7,200VA of surge headroom for motor loads and hard starts. Its hybrid charging mode pulls from solar and the grid together, with up to 80A of solar charging current.
Time-sharing charge and discharge scheduling lets you decide when the system pulls power and when it delivers it — useful for cutting utility costs on a time-of-use rate. Need more capacity later? Stack up to 6 units in parallel for a combined 21.6kW. Renewable Outdoors is an authorized RUiXU dealer, and every SUNON3.6 is backed by RUiXU's 3-year limited warranty.

Why the SUNON3.6 Stands Out
80A Hybrid Charging
Charges at up to 80A and can draw from solar and the grid at the same time, so the battery bank refills faster on cloudy days.
Time-Sharing Scheduling
Set when the system charges and when it discharges, so you can shift consumption off peak utility hours and keep more of your solar.
Stack Up to 6 Units
Start with one and expand — six SUNON3.6 units in parallel deliver a combined 21.6kW of output.
Works With Any 48V Bank
Lithium-ion, lead-acid, or a user-defined battery profile — pair it with the bank you already own or plan to build.
Rapid Shutdown Built In
De-energizes the PV array quickly to protect first responders — a requirement in most modern residential solar installs.
WiFi App Monitoring
The included WiFi dongle connects the inverter to RUiXU's app so you can check production and battery state from your phone.

Warranty
3-Year Limited Warranty
RUiXU's manufacturer page for the SUNON3.6 confirms the output rating, 48V battery compatibility, 80A charge current, 6-unit parallel capability, rapid shutdown, WiFi monitoring, UL1741 certification, and box contents. The output voltage, 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.

Every SUNON3.6 we sell is backed by RUiXU's 3-year limited manufacturer warranty.

RUiXU SUNON3.6: Frequently Asked Questions
Is the SUNON3.6 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.
What batteries can I use with it?
The SUNON3.6 works with lithium-ion, lead-acid, or user-defined battery profiles on a 48V nominal bank, with a usable voltage range of 40–60Vdc.
How much solar can it charge from?
The SUNON3.6 supports up to 80A of solar charging current, and can combine solar and grid charging simultaneously in hybrid mode.
Can I add more inverters later?
Yes. Up to 6 SUNON3.6 units can be stacked in parallel for a combined 21.6kW of output, so you can start with one and expand as your loads grow.
What's the difference between the 3,600W and 7,200VA ratings?
3,600W is the continuous output the inverter can sustain, while 7,200VA is its short-term surge capacity — the headroom that lets motor loads like a well pump or compressor start up without tripping the inverter.
Does it support rapid shutdown?
Yes. The SUNON3.6 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?
RUiXU backs the SUNON3.6 with a 3-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 SUNON3.6 purchase is backed by our Lowest Price Guarantee — if you find a better price elsewhere, call us at (303) 876-7654 before you order.
