Solar update

So here I am in Ballston Spa NY at a Cowboy Action Shooting weekend event. Temps went down to 39 degrees last night. Furnace set at 65 degrees. Watched a movie and some TV. Did a bit of Internet surfing. Woke up this am with my two group 31 batteries at 12.7v.
Every single camper next to me is running generators. I made two cups of coffee in my hotel version Kurig machine, listening to the radio and using lights and my WeBoost cell booster.
No Generator!

Still only used it one rainy day in the last year and three months.

Sun is just starting to come up and my 280watts of solar are already dumping 2 amps into the battery.

To say I'm pleased with how this is working out would be an understatement.

Love my solar!!!!

    Yeah. For a resting voltage that's too high. For a freshly charged battery connected to a solar charger with the sun out, it's about right.


    That may be true for "YOUR" batteries, but as an example my are 12.93 volts rested. Batteries are "not" all exactly the same chemistry and Specific gravities.

    That's amazing performance. 12.7 is full.
