Deye SUN-80K-SG02HP3-AU-BM6 Hybrid Inverter

1. Efficient by design

Like the rest of Deye’s high-voltage hybrid range, this model is built around a 160–1000 V lithium battery input, rather than a 48 V bank.

That brings some clear advantages:

• Higher round-trip efficiency – less energy lost as heat in cables and electronics
• Lower current on the battery side, so cabling is usually tidier and lighter
• Two battery inputs (80 A + 80 A) make it easier to build out larger battery stacks or split banks logically on site

For sites planning substantial storage – demand shaving, backup, tariff optimisation – the HV architecture helps your battery work harder for longer.

2. Made for complex and spread-out arrays

One of the standout features of the SUN-80K is its six independent MPPT trackers, each with two strings. 

That gives BSC Renewables a lot of flexibility:

• Allocate different trackers to house roof, sheds, carports and ground mounts

   

• Keep shaded or awkward sections on their own MPPT so they don’t drag down the rest of the system

   

• Use the available 128 kW PV input / 160 kW PV access power to sensibly oversize the array (within standards), so the 80 kW inverter has plenty to work with all year round

   

If your site has a mix of orientations, tilt angles or structures, those six trackers are a big advantage.

3. Built for real-world three-phase loading

On any decent-sized site, one phase nearly always ends up doing more work than the others. Deye’s 60–80 kW high-voltage hybrid range is designed for 100% unbalanced output, with key features like: 

• Support for heavily uneven loads across the three phases

   

• Comfort working in on-grid and off-grid modes

   

• Integration options for AC-coupled existing solar and diesel generators in suitable designs

   

For you, that means:

• The “busy” phase – often the one with big HVAC, lifts, chargers or process loads – can draw more without constant nuisance issues

   

• You’re not locked into a perfectly balanced board on day one; the system is more forgiving as loads shift or get added later

   

4. Sized for serious solar

From the Deye 60–80 kW series data, you get:

• Max PV input power (80 kW model): 128,000 W

   

• Max PV access power: 160,000 W

   

• Max PV voltage: 1,000 V

   

• MPPT range: 150–850 V

   

• Max operating PV input current: 36 + 36 + 36 + 36 + 36 + 36 A

   

In practice, that lets BSC Renewables:

• Run longer strings at higher voltage to keep cable losses under control

   

• Spread significant PV capacity across multiple roofs and structures

   

• Design a system where the array is big enough to feed both site loads and the battery, even outside perfect summer conditions

5. Smarts for tariffs, generators and future growth

The Deye series highlights: 

• Six configurable time windows for battery charging and discharging

   

• Ability to AC-couple to some existing solar systems

   

• Support for storing energy from a diesel generator in the right setup

   

• Up to 10 units in parallel for very large on-grid or off-grid systems

   

For your site, that translates to:

• Matching battery behaviour to time-of-use tariffs – charge mostly from solar and off-peak, discharge in peak windows

   

• Keeping reserve capacity in the battery for outages if continuity is critical

   

• A clear upgrade path, whether that’s more PV, more storage or additional inverters later
  

6. Monitoring and WiFi

Deye’s high-voltage hybrid platform supports WiFi plus RS485/CAN communications via its cloud system. 

Day to day, that gives you:

• WiFi monitoring set up by BSC Renewables during commissioning

   

• App and web access to see live solar generation, battery state of charge, and site import and export to the grid.

   

• Remote data (where available) to support ongoing tuning, fault-finding and performance checks
