I have been having some exciting exchanges with some experts in solar. We have been trying to determine how they calculate the size of the inverter, the battery bank and the size of the PV.
I have heard 4 batteries 4 panels.
I have heard inverters catch on fire
I have heard 3 kw in panels is too much for 4 batteries. (irrespective of the size)
I have heard you can't run AC on Solar
I have heard the system voltage has no bearing in calculating the battery bank or array size.
I have heard 4 200 AH batteries equal 800 AH. It does not matter if it is 12, 24 or 48 Volts.
I have heard panels are installed facing the east. (hint: the solstices and equinox)
I have heard I can installs panels under a tree or an obstruction.
I have heard. Solar does not work when it rains or when it is cloudy
I have heard solar does not carry Microwave or AC.
I have heard that PWM controllers work very well on huge installations.
We have seen 3 kw in panels with a 20 amp controller
I have heard we tell the customer the inverter size. If he wants to pump water, use his fridge, freezer, microwave and maybe run one AC 10 kva with 8 batteries.
What matters most is the size of the inverter capacity and the battery.
You only need enough solar panel to charge the number of batteries.
Please add your misconceptions and we will take them apart daily one topic at a time.
Solar will work better if we all understand how professionals arrive at calculations Thank you sir |
