Hi, need some advice and guidance - I have recently installed a second 100w solar panel (in parallel to another 100w one) due to low light conditions, to my 75/10 mppt controller. Whilst generating more solar power, the load consumption (3w led light on for 12 hours) has increased from 40w to 60w with no other changes. Any ideas what has generated this additional load consumption? Many thanks.
Please provide more details - about the solar panels and the system.
In general, if you add a second, identical solar module to the input of an mppt, then as long as the input voltage is not exceeded, the performance will be better if the modules are in series. (assuming the same orientation)
Hi, my set up is as follows :- 2 off 100w solar panels connected in parallel, feeding into a 75/10 mppt controller, which in turn feeds a 12.8v LifePO4 18ah battery, and a load consisting of a single 12v 3w led bulb which is switched on via a timer for 12 hours over night. In my original post, I should have said that the consumption (as detailed by the app) has increased rather than the load. I am on a steep learning curve so trying to understand the system.
