Hi all,
Solar question.
Set up is original 140w panel into TPS1230 solar regulator and into standard battery charger (Setec ST-III), charging 2 x new AGM 100AH (XTM).
Going fine but needing more solar as using up power a bit.
Bought some 160w fold out panels (Ridge Rider) and paralleled them into the TPS1230 solar terminals and have an Anderson Plug on the end to connect the folding panels. Open circuit voltage less than max open circuit allowable in the TPS1230 solar regulator so all good there.
First couple of weeks working fine. Pumping in 20A or so, saw 24A once. Regulator can handle 30a so ok there.
Last couple of days have only seen 4A or so and today only 2a or so (late arvo).
I tested portable panels and voltage coming out is around 14.4V so they seemfine.
Tested solar input terminals on TPS1230 and voltage is changing every half a second from 12 to 15 to 12 to 16 to 14 to 16 to 12 etc etc.
It shows this if I have portable panels connected or disconnected.
What could be causing the voltage fluctuations and is that why we aren’t getting enough juice in to the batteries (pulled up after driving all day in the sun and battery was only on 12.3V).
Could the TPS1230 solar regulator be rooted?
