Sigenergy's Hybrid Inverter

Sigenergy have launched into the Australian market with one of the most innovative hybrid inverter solutions I've come across. Scales from 5kWh to 3MWh+, can include a 25kW d.c. bi-directional EV charger, comes in single or three phase variants from 5-25kW, has a gateway device with built in 100A contactors to allow whole of house backup, can have a generator as additional backup to grid. Not to mention the best-in-class phone app!

Should I directly connect a set of 10 Kv or 13 Kv batteries for 1 phase to another inverter? Do the inverter panels from SIGENergy feel disgusting? What kind of inverter from SIG ENERGY do I need to service 13 KV on Phase 1? Which high-profile security should I choose? I have 10 bifacial panels but I don't know whether to connect them directly to the inverter from Sienergy or to the inverter and then to the battery and the inverter? The max inverter can be 5KV

[@RayJohnson1980]

if using in a 3 single phases building, could you use more than 5kw for each phase e.g. 7.5kw on phase 1 but use 2.5kw on phase 2 and 5kw on phase 3? for the total of 15kw or is it fixed to 5kw on each phase?

Are you try hybrid Deye for three phase system

Hi Glen, another great display of the features of this most versatile product. By the way I might have a most unusual application for Sigenergy equipment. Let's see... Regards Frank

Is a battery or gateway required or can this inverter work stand alone?

[@SmartEnergyLab]

Yes, inverter can work as just a solar PV supplied grid-tie inverter without batteries.

Can this unit work without a battery?

[@barriedear5990]

Can you add third party batteries to this? You mention battery port at 6.45

[@paulhutt891]

Is there only 3 DC inputs, so maximum of 3 strings to be connected with modern panels?

[@SmartEnergyLab]

Depending on the model they have 2-4 MPPT inputs. With the move to 1000 V max. for residential systems in Australia this year (fingers crossed), you could get 10kW/input with 400 W panels.

[@paulhutt891]

@@SmartEnergyLab 3 inputs on a 15kW inverter doesn't even allow for 33% oversizing, and that's with 12-13 panels on each string- massive oversight imo

[@SmartEnergyLab]

@@paulhutt891 Australia is moving to 1000 V dc for residential PV arrays this year... that'll allow 10 kW per input with 24-25 panel strings.

[@celts88-78]

What is the timeline for the 1000v PV allowance as it’s going crucial for uptake of the inverters with only 3 MPPTs for the 15kW inverter (should have been 4, oversight here)?
