Plans are well underway to expand the Solar on my 398M.
I have 4 more Aims 120 watt panels to add to the two I already have.
The plan is to return the Jaboni back to it's factory stock configuration, of one 300 watt panel as it works properly like that. I will run the 6 Aims 120 watt panels as a seperate system. Two series strings of 3 panels, with an easy option of being able to add one more string of three.
I have the Victron 250/100 controller for the new Aims array. This system would total 1020 watts expandable to 1380 watts with ease.
I have one question. The easiest way to run the wiring from the roof is to use the sattelite dish wiring channel. I already have the coaxial cable for the dish and the control cable running thru it. There are two empty slots in the roof plate for the dish. I am considering just running the new array wires thru these slots terminating them on the roof with short cables capped with MC4 connectors. Which would then have 2 into 1 MC4 connectors plugged in, and the two Aims strings plugged into those. My question is on the roof penetration method. Conventional method is to use a gland. That would up the difficulty level a lot. (new hole in roof, likely a different location etc) I can not see any downsides to my proposed method.
What are the thoughts on this?
if there is already two pannels installed, I would just add the 4 so that you have two runs of 3 in series. you may be looking at a different controler than what you presently have to do it, but you wouldnt be running any more cables from the roof down.
