I am not sure if this is the best place to ask, but I am trying to make a solar panel system which will charge batteries with excess energy and will be connected to the mains (i am going to try the lights circuit initially).
I also want a backup from the grid if the batteries run out and I am not producing electricity (like at night).
I am starting with a 300W panel http://www.naturalsparx.co.uk/product/2500638030/LG-Mono-X-Neon-G3-300W-Mono-PV-Module-Black.
I would need to connect this panel to a 3 phase MPPT charge controller, then batteries, then a True Sine Wave inverter to 230V mains to the circuit breaker.
Is there an inverter that will allow me to charge batteries when needed and power the mains when needed and take power from the grid when needed?
Is this a solar hybrid inverter?
