Hi,
I have been tinkering with grid-tie A/C micro inverters, and we have a huge power problem, with charges running to tens of thousands. Micro inverters require power from the grid for activation, simply to protect the line workers, so if the gird is down the micro inverter switches off. I wanted to reduce my power bill so I wanted something that could allow AC voltage to remain the same while reducing current flow to the least possible from the grid to power on the inverters.
I have worked on a couple of solutions, but I'm not happy with the end result, one was to be totally off-grid, which requires another pure sine wave inverter to continuously work off batteries to produce the pure sine wave, and the micro inverters will add the additional power required to run application, while a charge controller with charge the batteries.
I have about 1800w (600w x 3) micro inverters with same capacity panels. If I add a 600w pure sine wave inverter with batteries, I should get a usable 2.4kw system (1800+600, at-least in theory).
I want to know if there is someway I could use a direct power line from the grid to be connected to the micro inverter with least amp drawn to keep it functional but draw power from the 1.8kwa produced to run local appliances without tapping from the grid ? This will mean some sort of 3 way junction, where the input grid input will be limited and maximum power required drawn first from the solar grid tie inverters and then maybe very little from grid.
TIA for any help in this matter
Best Regards,
Ruben.
