Why are 12v battery chargers to unreliable

Glad to see Dual Pro on that list. A Dual Pro Sportsman Edition is the one that's been keeping my sump pump batteries happy for the last 5 years or so. They claim that series is "Fully Waterproof". I can't vouch for that since the whole purpose for mine is keeping water _out_ of my basement.

How do you measure battery capacity?

Has it ever successfully restored a sulphated battery?

That's what I said when I saw the 1kw kit for $1115. Bits add another $850 to that by the time I'm done.

Are they tilted properly, or just flat? 180 is pretty nice, but...

"Where are my climbing boots and chainsaw?"

Why is it inside, again?

I looked at Associated, their "maintainer" is made in China.

It's 90% of MPP for two 100W panels, on a PWM controller. I used my UT210E clamp-on to adjust them for the maximum current, though some misalignment didn't hurt much.

The high current, heavy cable parts are close to the load, which is the fridge and computer desk. The indoor layout makes sense for a closely watched experimental manual backup system but wouldn't for an automatic daily cycling one. Once I have a better idea of what I need and have space for I may move the batteries and a larger inverter into an outdoor enclosure, or change to AGMs or Lithium.

At this point I hopefully know enough to be able to snap up good deals I may happen onto, like these Home Depot panels.

Their KS-401 was "MADE IN USA of US and Imported Parts". Hmmm...

"MADE IN USA of US and Imported Parts" means they applied their label, printed in Mexico, an a Chinese Charger and put it in a box printed in India.

Nothing specific on that product - but that's about how loose the regulations are.
