I bought one each.
I have the harbor freight 45W kits and the new 145W panels available.
I have the ability to have both 12V and 24V battery banks with their own controler.
I have read that it is best not to max out the gti's sun-500g is actually 450w normal output power with 10.8v to 30v input voltage.
My question is how do I limit the watts in to the GTI?
Do I just add up the watts of the panels going to the GTI?
I plan to use 15a breakers in a squrare d power box. Two harbor freight to each breaker.
Each breaker would then have 15+15 watts.
I can flip breakers to add up in 30 watt each.
Therefore how many watts shall I flip to load the gti for a no worry install.
15 x 30W=450 which is the rated load.
If I run a computer case fan to keep it cooler, should I run 10x30W=300W or would 8X30W=240W be better.
