Sunsynk All-In-One 3.6 kVA / 5 kVA, Single-Unit Inverter and Battery System

The Sunsynk All-In-One simplifies the path to energy independence by combining inverter and battery storage in a single wall-mounted unit, reducing installation footprint and component complexity from the outset. Homeowners and small business owners get a solar-compatible system that manages grid power, battery charging, and solar input together, without the need to coordinate multiple separate systems. With 3.6 kVA and 5 kVA options available, it’s a practical entry point that can scale as your energy requirements grow.

Product Features

Inverter And Battery In One Unit
Available as 3.6kVA with 3.84kWh, or 5kVA with 5.12kWh. One enclosure, one wall position, one install. Fewer components to specify and fewer connections to fail.
Near-Instant Changeover
Shift time between bypass and inverter of 10ms, faster than the 20ms typical of this category. Equipment sensitive to even a brief interruption stays running.
Handles Start-Up Surge
Peak output apparent power of 7,200VA and 11,000VA, twice the continuous rating, for motor and compressor start-up.
Solar Compatibility
Maximum DC input of 4,500W and 6,800W against 3,600W and 5,500W of output, with a 500V maximum input voltage, MPPT tracking from 120V to 450V and a 150V start-up.
Tunable Charging
Maximum charge current configurable at 60A or 90A, and discharge at 80A or 120A. Charge behaviour is matched to the installation rather than fixed at the factory.
Conversion Efficiency
97.6% maximum efficiency, 99.9% MPPT efficiency and 94.0% battery-to-load efficiency, the last of which is the figure that actually governs how much stored energy reaches your appliances.
Integrated Protection
Battery over-charge, battery low-voltage, over-temperature, output short-circuit, output over-voltage and output overload protection, all built in.
Passthrough
Maximum bypass current of 40A with total harmonic distortion below 3% on a resistive load.
Planning
701 × 544 × 182mm at 51.7kg for the 3.6kVA, and 901 × 624 × 182mm at 82.0kg for the 5kVA. The larger unit is a two-person install onto a structurally sound wall.

 Trustindex verifies that the original source of the review is Google. The service team and support were fantastic in dealing with my machine even though it’s definitely a much older model

 Trustindex verifies that the original source of the review is Google. Great to see some places still doing honest business. I recently sourced an inverter for my small business from Oxbow and was amazed at how much care and consideration they gave to my purchase. I had a salesperson on site for assessment and within a week had my inverter installed and functioning perfectly. Very impressed with their service and urgency.

 Trustindex verifies that the original source of the review is Google. We recently upgraded to a Fujifilm C750 through Oxbow and the improvement in print quality has been noticeable immediately. Their technician handled everything from delivery to network setup and even configured scan-to-email for the whole team. What stood out was how smoothly the transition happened without any downtime.

 Trustindex verifies that the original source of the review is Google. We chose a Fujifilm device through Oxbow after comparing a few options. Their consultant gave us honest advice based on our usage rather than pushing the most expensive option. The machine has performed well so far. Appreciate the transparency.
