Meanwhile, I have 3 of these indicators in the house of a homemade solar system!
Two of the show run through for over 5 months and 3 for a month.
I have seen in each floor an indication how full my battery is still and I still can use all or make his better.
The show thus work of 11-to 15 volts continuously.
The power consumption is so low that my solar controller makes no difference because if does not charge or illuminated, lit LEDs in various bathroom and hallway permanently.
Consumption of these will always be specified with 0.1 and now 3 voltmeter are gotten and the consumption has not risen to 0.2 times.
My controller can also 0.2 Show that happens when the lighting in the guest bathroom, for example, so far as the own consumption needs but be relatively low.
Those things are not hot, not even warm and whether ads on the Volt I'm not sure.
But I can say that when I connect all 3 of a cable all 3 identify the same voltage!
So no matter how I can praise these things only to heaven.
The installation in the car I was a bit cautious ... I do not think an intervention into the electrical system with the material possibly. Not allowed for this is due to damage not yet times by bad luck from a rigorous evaluators could be made etc. for the event. ..
If one gives up the ghost can be found here promised an update!
