Thanks Juiceman for the info.
But when I had a small battery bank.
To keep from overcharging.
Lithium battery setup only charges to set voltage...
If you have a voltage meter.
Check that the P20L controller is showing the same voltage.
I would change reconnect to 12.4 and flood to 13....
Still at 90 watts for (3) 100 Watt panels.
I even tried another MPPT Controller.
So in spring I will pull them all again.
And put up the two from...
Just changed the panel.
Power output soon.
New panel has a few bubbles and a trace almost sticking above the clear coating.[ATTACH] [ATTACH]
Trouble with the flex panels.
This just happened this week.
(3) 100 watt panels in series with MPPT Charge Controller.
Max output 58 Watts.
VertaMax 1500 Watt 12V Battery Power Inverter DC to AC Car, RV, Solar, RV,
Windy Nation's VertaMax 1500 Watt DC to 120 AC Modified Sine Wave Power...
I just installed some more of these panels.
There was a note with them.
Do NOT connect these panels in Full Sun.
Or risk damage to the panels.
That is normal.
So the controller has voltage and will be ready for solar input.
Connect solar first and risk damaging the controller.
Wind KWH since I installed the Classic.
It is 114 KWH for this year.
PWM 24 input drops to battery voltage but maintains amps.
So in low light you would see some power over a 12v setup.
Mppt is the way to go for the...
The charge controllers I have I set for lithium batteries.
As that will allow the max charge.
Then I set for 14.0 on battery volts.
Testing the voltage at the battery connection on the P30L shows 0 volts.
This would be the problem.
It must not be hooked up.
And maybe your...
It's really hard to tell.
PWM drops panel voltage to battery voltage.
Then you use current and battery voltage for watts.
Being a 200 watt will...
On the charge controller push mode button twice.
That should be battery type.
In order to set an eligible
interface, press the 'MODE' button for...
Sorry I'm so late. Most controllers will not work below 10 volts DC on the input.
This one shows 10.7 and 11 VDC min on the battery.
