Deye SUN-29.9K-SG01HP3-AU-BM3 Hybrid Inverter

1.Built for efficiency and scale

This series uses a 160–800 V lithium battery input with two independent battery connections. 

What that does for you:

• Higher round-trip efficiency – less energy lost as heat in the cables and electronics

   

• Lower current on the battery side, so the wiring is usually neater and lighter

   

• Designed to suit modern stackable HV battery systems already running in this voltage window

If you’re planning a decent-sized battery bank and want it to perform well over many years, HV storage is a big plus.

2. Made for tricky roofs and multi-array sites

Unlike the smaller high-voltage models with two trackers, the SUN-29.9K gives you three MPPTs. 

That opens up options like:

• One tracker on your main house roof, another on a shed, and a third on east/west faces

   

• Keeping shaded or awkward sections on their own MPPT so they don’t pull down the whole system

   

• Mixing different tilt or orientation arrays while still running each at its sweet spot

   

BSC Renewables can use those three trackers to squeeze more useful energy out of the site you’ve got, not the one you wish you had.

3.Big DC capacity for serious solar

Deye’s 29.9 kW model boasts:  

• Max PV input power: ~47,840 W

   

• Max PV access power: 59,800 W

   

• High DC voltage (up to 1,000 V) with a wide MPPT window

   

In simple terms: 

• You can run a lot of panels into this inverter

   

• There’s room to sensibly oversize the PV (within standards), so the 29.9 kW of AC still gets well fed in winter and on cloudy days

   

• Long strings and higher DC voltages help keep cable losses down on larger roofs and ground-mounts

4.Suited to real-world three-phase loads

This model is suitable for on- and off-grid use. 

Key implications for you:

• It’s comfortable in sites where one phase does more work – for example the phase with the EV charger or big machinery

   

• It’s designed for mixed residential and commercial loads, not “perfectly balanced” lab conditions

   

• When you grow – more gear, more tenants, more equipment – the inverter isn’t the first thing holding you back

5. Smarts, generators and growth paths

This model: 

• Supports multiple time periods for battery charging and discharging (good for time-of-use tariffs)

   

• Can work in designs that store energy from a diesel generator

   

• Parallel operation (commonly up to 10 inverters) lets you scale well beyond 29.9 kW if needed

   

So your system can be tuned to:

• Charge mostly from solar and cheaper grid periods

   

• Discharge during peak rates

   

• Keep battery in reserve for outages, instead of draining it every single night

   

6. Monitoring and WiFi

Deye platform supports WiFi, RS485 and CAN communications for monitoring and integration. 

What does that mean day to day:

• BSC Renewables will set up the WiFi plug and cloud monitoring when they install it

   

• You can log in to see:

   

  • Live solar generation

     

  • Battery state of charge

     

  • How much you’re buying from or exporting to the grid

     

• Remote data (where available) makes it far easier to spot issues early and tweak settings over time
