FAQ

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!

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!

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

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!
