Deye SUN-50K-SG01HP3-AU-BM4 Hybrid Inverter

1. Built for big storage

This model uses a 160–800 V lithium-ion battery input with two independent battery ports and up to 50 A + 50 A charge/discharge current. 

What that means for your project:

• Higher round-trip efficiency than a comparable large 48 V bank – less energy lost as heat
  
  
• Lower current on the battery cabling, so the installation is typically tidier and uses less copper
  
  
• A natural match with modern stackable HV battery systems designed to sit in this voltage window
  
  

If you’re planning meaningful storage (not just a token battery), HV architecture helps squeeze more out of every kilowatt-hour.

2. Made for complex and spread-out arrays

Unlike smaller models, the SUN-50K has four independent MPPT trackers with two strings each. 

That gives BSC Renewables a lot of design flexibility:

• Put one tracker on your best north-facing roof, another on east/west, and the others on sheds, carports or ground mounts
  
  
• Keep shadier or awkward sections of the array on their own MPPT so they don’t drag down everything else
  
  
• Take advantage of the 75 kW max PV input / 100 kW PV access power to oversize the array sensibly (within standards), so the 50 kW inverter stays well fed in winter and on cloudy days.
  
  

For larger sites, those extra trackers translate into more usable energy across the year.

3. Handles real-world three-phase loads

In the real world, one phase always works harder than the others. Deye’s AU data shows this series supports 100% unbalanced output, with each phase able to supply up to 50% of the inverter’s rated power. 

In practice:

• The “busy” phase often the one with EV chargers, big A/C or machinery – can draw more without constant nuisance issues
  
  
• You don’t have to obsess over perfectly balancing every circuit now and in future upgrades
  
  
• It suits mixed residential/commercial boards where the load profile changes over time
  

4. Built to scale, and to play nicely with existing gear

With Deye’s hybrid series, you get:

• Up to 10 units can run in parallel, on grid or off-grid
  
  
• Supports AC-coupling, so it can work alongside some existing solar systems
  
  
• Can be configured to store energy from a diesel generator in the right design
  
  
• Offers six time periods for battery charging and discharging, so behaviour can follow your tariff and usage
  
  

So you can:

• Start with one 50 kW hybrid and add more inverters later if the site grows
  
  
• Line the system up with time-of-use tariffs charge mostly from solar and off-peak, discharge during peak rates
  
  
• Keep battery reserve for outages, instead of draining it flat every night

5. Designed and approved for Australian conditions

Deye inverters are built for Aussie weather: 

• IP65 rating suitable for outdoor wall mounting
  
  
• Operating from around –40 °C to +60 °C (with derating at higher temps)
  
  
• High efficiency (max ~97.6%, MPPT >99%)
  
  
• AS/NZS 4777.2 compliant and listed by local wholesalers with a 10-year product warranty
  
  

In other words, it’s built as a long-term backbone for Aussie sites when installed by a licensed solar electrician.

6. Monitoring, comms and the WiFi plug

This model supports communications via WiFi, RS485 and CAN. 

Day to day, that gives you:

• WiFi monitoring set up by BSC Renewables as part of the install
  
  
• App or web access to see:
  
  
  • Live solar production
    
    
  • Battery state of charge
    
    
  • How much power you’re buying from or exporting to the grid
    
    
• Remote data (where available) that makes tuning and troubleshooting far easier over the life of the system
