I have 600 watts of solar panels
in 2 separate intallations on my cat. One set is 4 90 watt panels
hooked to a 30 amp regulator
and the other is 2 120 watt panels
hooked to another 30 amp solar regulator
. Historically the 2 systems together would register 50 or 60 amps charging
in full sun and before the regulators they would put out 17+ volts.
I left the boat for 2 months and when I got back, the charging
seemed slow, so I checked the panels and only had around 14 volts charging before the regulators. What is strange is the both of the separate systems were exactly the same...Same charging rate. Also in full sun, both systems together were only putting out around 25 amps.
One thing is that there is lots of lightning
here right now and many boats have been hit. I am wondering if something could have got blown out, but again, both systems are doing the same thing.....
