I have 2 small panels on my roof (640 x 550) not sure what watt they are
.
These have been wrongly wired into a cheap controller and then down to the battery.
I am adding a 100w panel and have been advised by a solar company the most efficient way to wire them is to use 2 separate systems. One with the 2 small panels in parallel and one with the 100w on its own.
They advised connecting them to the batteries via their own controllers.
This is OK for someone with normal regulators but I am fitting a Schaudt LR1218 which will connect to my electroblok EBL 264-7.
Would it be OK to connect the 100w to the LR1218 and the other panels direct to the battery with a cheap controller or would this upset the EBL?
Would it be better to join all the panels in parallel and connect to the LR1218, and lose a little efficiency.
I have contacted Schaudt and whilst waiting for a reply thought I would access the large knowledge base on here
Solar is a minefield. I spent the last 5 days reading various posts but cannot find anything to answer my questions.
I have fitted solar 3 times previously, twice through regulator to batteries and once through a Sargent box. It is just Schaudt I cannot figure out.
Help needed
