When was the 50 watt solar panel upgraded to 100 W

I just finished a new 400 watt system that was showing a 23 amp output into the controller and 26.5 amps into the batteries at solar noon with a Blue Sky 3024iL controller.

I seriously doubt you will ever see 30 amps from 200 watts of solar regardless of the conditions.

I'm a bit confused by the 3 posts from Lewster, Shark, and McRider, including Lewster referencing 30amps.

Anyway, Attached is a pic of my monitor. I might be misinterpreting the monitor, or it could be calibrated incorrectly. This is a 200w system (rigid panels) with 10g wiring, and a MPPT charger/controller. I don't really know solar, I'm just reading back the specs of a system someone else installed for me.

The reason I'm interested in this is whether to try to fit another panel (i.e. 300w total).

thanks for any input.

(btw ... how you folks insert an image as opposed to attaching?)

Those are panel volts, not amps into the battery.

Your meter is displaying VOLTS, which are probably the output from your solar panels. It will not display the amps it is sending to the batteries unless you have a shunt installed on your negative battery cable ( positive for you budding Victron users).

Big difference!!

You're right!!
