The 3 phases, 127v each is the standard configuration here in south Brazil, for big house. This is why I am trying to figure out some cheap solution without the need to rearrange the devices. Is there an affordable (~$200) 3 phase inverter at max 4kw? No need to be hibrid with solar panel...
One idea that comes into my mind is to put an Variable Frequency Device (VDF) single to 3 phase used for motors to connect in my grid. Would this work?
Ok. Got it.
Is there any way to instal 3 different cheap inverter and then synchronize them in some way?
My concern is if I change the devices later between the phases.
The power amount should not exceed 500w (peak of 1000). The capacity of the system should be around 5.000kwh
The average price of a deep cycle battery that I can source locally here is around $100 for 12v 100a
Hi
I am willing to build a very cheap battery backup system for my home, only for blackouts.
What is the cheapest way to do that? Is it possible to connect 3 cheap inverter for each phase in a lead acid battery bank? Or is there any cheap option for a 3 phase inverter?
My critical devices...
