Affordable Charge Controller for AGM Battery

Thanks I will look into that

You will also need to look into a second 200w panel because only 1 will not provide the 12 to 13amps for charging your battery properly.

I have a 50w DC light that I am looking to power for 12 hours a day. It has a voltage regulator on it to help manage the power consumption/brightness. I am hoping to fine tune the battery/panel power this way.

Thanks for the recommendation.

You know you can run a 50w A/C Bulb Direct off battery. If not now you do.

It is not a safe or practical way to light up an AC bulb directly using a battery.

SunEagle should I not expect 16amps from a 200 watt panel
200/12 = 16.6 ?

Not really. The amount of amps the panel can produce at it's higher peak is usually the Imp rating.

Typically a 200watt panel would have a Vmp ~ 18 - 19volts which would make the Imp ~ 11amps (200w / 18v = 11.1amps) at best but more likely about 10amps tops.

In theory (Lab) the bulb does not know if its ac or dc. But the big question where do you get a Incandescent Bulb.
And yes bulb was always dangerous with filament running at 2500 deg C

Ok so my next q is would a quality MPPT controller be more reliable than the elcheapo that is supplied with panel I think it is called a sun lite Chinese made? I was thinking a victron 75/15 ?

I would be nice if you had something positive or constrictive to add to this discussion.

Knowing who to ignore is vitally important, if you don't want to get hoodwinked

You're on the right track in my opinion, victron has a five year warranty and a great reputation. Tons of very cool and Technical looking stuff on their website.
