FAQ

Is this a MPPT tracker?

This is not a true MPPT tracker, for information on why we did not design it as a true MPPT,

read our design notes! (http://adafru.it/aN7)

Why didn't you make this an MPPT?

For low power solar charging of lithium ion's, its not necessarily a better way to charge. For

information on why we did not design it as a true MPPT, read our design

notes! (http://adafru.it/aN7)

BUT I HEARD THAT MPPT IS THE BEST!!

For large multi-watt solar arrays that are charging lead acid batteries, you will want to get

an MPPT charger. For small cells, its not necessarily more efficient. For information on why

we did not design it as a true MPPT, read our design notes! (http://adafru.it/aN7)

OK so how does it work?

Good question! For information on how this charger works, read our design

notes! (http://adafru.it/aN7)

What solar panels can I use?

Use any rigid, flexible, monocrystal, polycrystal, etc panels with 6V rating (12 'cells') for the

best performance

We've tried 5V panels and they don't work. 5.5V panels sometimes work, 6V is really the

best!

Can I charge with a solar panel on my windowsill?

The charger will draw as much current as possible, but the efficiency of the panel will be

much lower. Solar panels must not have any glass or shade to work efficiently, they must

be outside, pointed as best as possible directly at the sun!
