RUiXU SUNON12 12kW Single/Split-Phase Off-Grid Inverter: Frequently Asked Questions

Is this a hybrid inverter that can export to the grid?
No. The SUNON12 is an off-grid inverter — it charges its battery bank from solar and from grid or generator power (Ruixu calls this SUB mode), but it doesn't feed power back into utility lines.
What battery voltage does this work with?
It's built for 48V battery banks.
Can I run more than one unit together?
Yes. Ruixu rates it for parallel operation with up to 6 total units, for a combined 72kW system.
How many solar strings can I connect?
It has dual MPPT trackers rated at 99% tracking efficiency.
Can I select 120V or 240V?
Yes, the AC input is selectable between 120V and 240V, giving you single or split-phase flexibility.
What's the difference between Smart Load Output and Bypass Output?
Smart Load Output (63A) is what the inverter itself powers day to day. Bypass Output (up to 125A) lets grid or generator power pass through directly for higher-draw situations.
What's covered under warranty?
Ruixu's published warranty terms are specific to its battery products — we don't see a separate stated warranty term for this inverter on Ruixu's site. Call us at (303) 876-7654 and we'll confirm current inverter warranty terms with Ruixu before you order.
Can I monitor it remotely?
Yes, it includes a WiFi dongle and connects to a companion app for remote monitoring.
Do you offer financing or price matching?
Yes. We offer 0% APR financing through Affirm at checkout, and our Lowest Price Guarantee applies. If you find this Ruixu gear cheaper at another authorized dealer, call us at (303) 876-7654 before you order and we'll take care of it.
Are you an authorized Ruixu dealer?
Yes. Renewable Outdoors is an authorized Ruixu dealer, and every unit we sell ships new, in factory packaging, with Ruixu's full warranty intact.
