Kalhuohfummi keeps track of your solar energy production

Kalhuohfummi is a battery specially designed for solar energy storage. Its charging electronics are engineered to ensure highest efficiency when transforming energy from a solar panel. But the biggest feature ist the smart chip embedded in its circuit: It will keep track of your solar energy production and store this data for 42 days. Enough time for you to connect “Kal” to your computer and upload your solar data onto your online profile. Every upload will be shown on your personal counter and earn you badges and rewards on our community.

For instant charging feedback

Kal’s four-digit LED charging display does not only show you how full its batteries are, it will also blink faster, the more energy you are generating. It’s the perfect feedback for adjusting your solar panel to just the right angle.

Of course you can also quickly recharge your “Kal” using a separate AC Wall Charger. However, Kal will notice you’re trying to feed it AC electricity:

Its charging indicator will turn red and you’re not going to get Solar Credits on your counter for these charges.
