Just trying to clear something up in my head.
As many of you already know, I am currently constructing a new observatory. I will have a solar power system that will comprise 2 X 6V 550amphr heavy duty AGM batteries (wired in series to give 550amphr @ 12V), being charged by 4 X 170W 12V solar panels via a 60amp MPPT regulator. All power for the observatory will be supplied through a 2000W 12V-240V pure sine wave inverter connected to the batteries.
This battery storage will be adequate to power the new observatory and equipment even on the very longest 14hr+ nights in winter (approx. 350amphr) but I envisage some nights, especially these long winter ones, where there are two (or more) clear nights in a row but it turns cloudy during the day in between and the batteries aren't getting enough power from just the panels for sufficient charge ready for the next night, I'd like to have a small pure sine wave inverter generator just to help charge the batteries, when required.
How do I use the generator in this scenario? Do I simply run the generator and have a simple regulated battery charger plugged into the 240V socket on the generator and connect this to the batteries and charge as desired? Will it matter if the panels, via the regulator, are still connected and charging too?
Just need to get my head around how to do this..?
Thanks for any feedback
Mike
