Blended power

Recommended Posts

I have been reading some posts, and come across the term blended power.

Is this where the inverter uses some of the batteries power and combines it with grid power to meet the demand of the load?

Eg. If you turn the oven on and there is a high draw.

Which inverters are capable of doing this? Would an Expert inverter be able to do this?

Yes. Though often also solar power blended with grid/generator power.

Note that "blending" of solar power and battery power is generally too easy, and is not considered real "blending".

Axperts generally can't, with the exception of a few models such as the King and possibly the Aerox (the Aerox is a weird model that only seems to be available in Pakistan). The Axpert King has dual conversion, so that blending of all power sources (PV, battery, grid) is possible in most modes and when the inverter proper isn't overloaded.

Models with the 450 V max solar charge controllers (e.g. Axpert MKS II, the "II" is important) seem to have the ability to blend solar power with grid power under certain conditions. These models aren't legal in Australia, so I don't know much about them.

Unfortunately, all Axpert inverters are resold, and there is little to no consistency amongst the resellers' model names, so when considering a particular model, it's important to first figure out what Voltronic Power model it is. Voltronic Power are the designer and manufacturer (except for the illegal clones, a whole other story).

Thanks Coulomb.. appreciate the feedback. So the king would be Axperts top model then.  Where do I learn more about the various models that Axpert manufacturer?

Depending on the amps that’s drawn vs the (real world) amps the inverter can supply.

it would be nice to have a 12kW inverter but that’s out of my budget (and plans). And probably illegal in a future world.

My hybrid 4K inverter yesterday tripped instantaneously when the mains tripped whilst the borehole pump was running. When the inverter took over (all by itself) the  pump started up but the 34  amps required for starting the pump overpowered the inverter. When it’s running supported by the mains the inverter will register 128%  I make it a point not to start it or let it run on the inverter.

Nice test but not to be repeated.

Despite the name, I would not say that. It seems to me to be a niche product. The double conversion adds cost and reduces efficiency (both slightly). I could be wrong.

Surprisingly, from the manufacturer's web site. Which is voltronicpower.com.
