Hey there,
I recently purchased the 600W Kit from you guys, and am trying to confirm my plan.
The current plan is to have 2 parallel strands of 3 100W Panels so I have a 24V system going into the 40A MMPT Controller (which is the recommended setup I believe from your website info).
FROM the MPPT Controller into the batteries, I'd like to use a 12V Battery bank (Consisting of 2 parallel strands of 6V batteries).
The MPPT Controller can manage 24V from the panels, and 12V to the batteries, am I correct?

Also, the reason I'm thinking this would work best if possible for me is that 12V Inverters are WAY cheaper than 24V inverters, and I want to avoid the extra cash drop if at all possible, so the 12V battery bank seems the way to go if the controller can do that. Thanks.

Yes, is your answer, if you bought the MPPT 40 from Renogy, That is why you hook the batterires up first, so the controller reconginzes them. Advantage of using 24v panesl, is smaller wire can be used and less heat loss.

we live completely off grid using renogy products. be glad you stuck with a 12 volt dc system. if you go with a higher voltage you cant hook nothing up 12 volt. as for batteries we use the v-max 155ah agm 12 volt first time buyers on there web site get a discount. as for a aerator for your pond, look into a solar powered 12 volt pump they use for solar water heaters. as for lights we use under cabinet led lights. they come with a transformer on the end. I cut the transformer off and hooked it to 12 volt battery bank. we got our solar panels on a pole that can turn. as the sun moves through the sky ill turn the panels following the suns movement all day.
