Hi there can someone please advise my next step for closing the gap to off grid power
I currently have the following
6kw of panels , b&b 5kw inverter linked to grid.
Produce between 26 and 35 kwh per day throughout the seasons
Consume between 500 - 1000 kwh per 90 days peak and 500 kwh average off peak 3kw and 1.5kw aircons used a lot during summer no heaters during winter
I have also installed a timer on the 125l hot water system so i control timing of energy consumption
I also have a :
1kw stand alone with 1 x 160ah 12v battery , 30amp controller , operating 2 x house light circuits with 8 x 12v led bulbs and 2 x 12v ceiling fans , lights and fans never run out of power and 1 x spare wire ready for 12v upright fridge when existing fridge dies
I also have 6 x 160ah AGM batteries on float charge doing nothing.
My challenge is to be able to run at least one aircon after 6pm till midnight and my cpap machine and fridge ,ALL NIGHT AND OFF MY BATTERIES and if batteries run low, switch back to grid and recharge off my grid and solar the next day, remember i dont need lights , the stove is gas .
Is there a cost effective way to set this up
